Introduction

The following starch grain comparative collection comprises 25 families, 63 genera, and over 100 different species of angiosperms (see tables below). The majority of the plants are featured in Chapter 2. When available, conspecific or congeneric taxa were also included in order to assess the range of variability present in starch grain morphology between closely related taxa. Some of the species presented in Chapter 2 are not included in this discussion. Their absence is due to either their lack of starch (such as oily seeds and nuts) or the author’s inability to obtain samples for this research. This collection is ongoing and will remain a work in progress for some time.

Starch Grain Taxonomic Keys Introduction Chapter 2 presents a brief review of the range of possible plants utilized by Native peoples of the Middle Atlantic region. The remainder of this supplementary material describes the starch grain assemblages from many of these taxa. Presented here are several keys intended to guide the reader, through a series of decisions, to a proper identification of an unknown starch grain/assemblage. To use these keys, begin by carefully reading each step and then examining the characteristic/characteristics of your specimen. Decide which statement best represents the grain in question. The name and family of the taxon will then lead to further descriptions of the entire starch grain assemblage. Be sure to evaluate more than one example/grain exhibiting the characteristic in question. Once a tentative identification has been made, check each description for all species listed within that genus.

In no way does the following attempt to detail all the identifiable taxa covered in the supplemental material; rather, the goal is to present some of the more obvious attributes useful for distinguishing between major economic taxa.

Master Keys

The following aims to establish a starch grain classification using a hierarchy of discrete categories based on diagnostic characteristics present within a group and rare in its nearest neighbors (Renvoize and Clayton 1992). Within the taxa studied for this project, six main categories were assigned based on a three-dimensional representation of the overall shape of the diagnostic starch grain. Attributes or characteristics included within these keys were selected based on their diagnostic value (see Henry and Piperno 2008; Holst et al. 2007; Pearsall et al. 2004; Perry 2001, 2002, 2004; Piperno et al. 2000; Piperno et al. 2004; Piperno and Holst 1998, 2004; Torrence et al. 2004; Torrence and Barton 2006; Zarrillo and Kooyman 2006). Not all grains exhibit diagnostic characteristics needed for identification purposes, some will exhibit morphologies widely represented across unrelated taxa, and still others may in fact possess characteristics of unrecognized taxonomic value and only through further comparative work will

these traits be understood. For these reasons, many starch residues may tentatively be unidentifiable or identifiable only at low taxonomic levels.

Plant Taxonomy

Family: Acoraceae Genus: Acorus Species: A. calamus L. (calamus)

Rhoads and Block (2000) describe this species as growing to ~6 feet, with long lanceolate leaves ¾-inch wide with pronounced midrib, aromatic, with stout rhizomes. Spadix also stout to about 4 inches long. Usage: Numerous ethnobotanical documents describe the use of A. calamus within Native economies (Black 1980; Johnston 1987; Rousseau 1947; Tantaquidgeon 1972). People throughout North America used the rhizome for a wide range of medicinal purposes including stomachaches, colds, heart disease, headaches, sore chest, and cramps. Popular ways of preparing these medicines involved mashing the rhizome into a poultice or chewing the raw root. Description of Starch: Assemblage (rhizome) primarily comprised single to compound grains, with clusters also present in high frequencies. Grains tend to be quite small, 6 × 4.5 µm, and highly variable in morphology (ranging from irregular subrounded to subangular domes, ovals, kidneys, and elongates). Small clusters comprising two granules can be recognized when viewed under cross-polarized light. Forty percent of the assemblage exhibited extinction cross distortion either distally or medially. This characteristic obscures portions of the grain, resulting in weak birefringence. (See Reichert 1913:235 for more details.)

Figure: Acorus calamus.

Distribution: http://plants.usda.gov/java/profile?symbol=ACCA4.

Summary: Acorus calamus Starch is produced in moderate levels within the rhizomes of this taxon. This assemblage consists of forms of taxonomic value. These are generally compound grains comprising two to four granules and exhibiting an elongated bent form that appears subangular and often blocky with rounded corners (Reichert 1913:235). The extinction cross appears wavy (actually composed of multiple crosses). Works Cited: Black, M. J. 1980 Algonquin Ethnobotany: An Interpretation of Aboriginal

Family: Alismataceae Genus: Sagittaria Species: S. latifolia (duck potato)

Crow and Hellquist (2000) describe this species as a perennial or annual herb, submersed or emerged, propagated by rhizomes and/or edible tubers. Leaves are extremely variable, ranging from sagittate to lanceolate, ribbonlike to subulate, and fruit achenes in globuse clusters. Usage: Throughout North America researchers note the use of S. latifolia tubers by historic American Indian people for dietary and medicinal purposes (Barrett 1952; Castetter and Bell 1951; Densmore 1974; Gilmore 1919; Hamel and Chiltoskey 1975; Rogers 1980; Smith 1928). Preparations of these tubers include boiling, roasting, peeling, slicing, and pounding. Some also mention the tubers were eaten raw. Their taste and appearance are compared to potatoes (see Barrett 1952; Densmore 1974). Description of Starch: Assemblage (tuber) primarily comprised single (simple) irregular rounded to subrounded globular, oval-shaped grains. These range in size from 7–27.5 µm, with an average size of 16.54 × 14 µm. Fissures are common and usually occur as longitudinal or tripartite Y shapes. Hila are situated in a semi-eccentric position. Discontinuous lamellae are evident in a small percentage of the assemblage. Also noted are radial marks extending out from the hilum. Birefringence tends to appear both curved and straight; arms tend to expand at the margins.

Figure: Sagittaria latifolia.

Distribution: http://plants.usda.gov/java/profile?symbol=SALA2.

Summary: Sagittaria latifolia Starch is widely produced within tubers of this species on a seasonal basis. The globose, irregular spheres with faint traces of concentric lamellae and fissuring in a tripartite Y pattern are of taxonomic value. Works Cited: Barrett, S.

Family: Apocynaceae Genus: Apocynum Species: A. cannabinum L. (Indianhemp)

This species grows to approximately 4 feet in height. Leaves are opposite, ovate to lanceolate in shape, and up to 6 inches in length, mostly petioled; corolla pink. Usage: Although widely known for its high-quality fiber, the rhizomes of Indianhemp also often appear in ethnobotanical studies of North American Native peoples. Many accounts describe people using the rhizomes for medicinal purposes. The Iroquois used it as a blood purifier and to clear yellow eyes (Herrick 1977). Other groups used it to treat pox or dropsy or as a laxative, and some even describe it as a universal remedy (Hamel and Chiltoskey 1975; Smith 1928). Description of Starch: Assemblage (rhizome) primarily comprised single (simple) elongate, cuneate to oval forms. These grains tend to be irregular. Hilum position varies from semi-eccentric to eccentric, the former occurring with the greatest frequency. A linear depressed medial area is often witnessed. This feature appears similar to a medial valley. Birefringence is well defined. Birefrigent arms tend to bend and be overall rather wavy.

Figure: Apocynum cannabinum.

Distribution: http://plants.usda.gov/java/profile?symbol=APCA. Summary: Apocynum cannabinum Starch is produced in moderate quantities within the rhizomes of this taxon at least on a seasonal basis. This assemblage consists of forms of taxonomic value; particularly

those elongated bent forms, <17 µm in size with eccentric hila and a slight longitudinal fissure/depression. Works Cited: Hamel, P. B., and M. U. Chiltoskey 1975 Cherokee Plants and Their Uses—A 400 Year History.

Family: Araceae Genus: Peltandra Species: P. virginica (L.) Schott (arrow arum, tuckahoe)

Emersed perennials, with thick fibrous or subtuberous roots, leaves basal with long petiole, sagittate to hastate shaped, fruit amber or green berry (Crow and Hellquist 2000). Usage: As Chapters 2 and 4 describe in greater detail, ethnohistoric accounts documented Native peoples of the Middle Atlantic region utilizing the robust vertical rhizomes of this species for dietary purposes (Kalm 1937; Smith 1986 [1608]). Description of Starch: In the assemblage (rhizome), single (simple), regular, rounded, elongated oval, and oval forms occur with the greatest frequency. Elongated forms tend to taper distally, often exhibiting a flattened distal surface. Domes/hemispherical grains are also present in the assemblage. Grains range in size from 7.5–40 µm and have an average size of 21 × 14.4 µm. Hila mainly occur in the eccentric position, which is generally open. Initial transverse to slightly curved transverse fissures witnessed. Concentric lamellae are common although not visible in the entire assemblage. Cracking, which appears as two ragged lines beginning at the hilum and expanding distally, is noted. Individual double-pointed calcium oxalate crystals (raphides) and bundles present.

Figure: Peltandra virginica.

Distribution: http://plants.usda.gov/java/profile?symbol=PEVI.

Summary: Peltandra virginica Large quantities of starch are present in the subterranean storage organs of P. virginica. The elongated forms (two to three times longer than wide) with visible concentric lamellae have only been noticed in this species, thus making this morphology taxonomically valuable.

Genus: Arisaema

Species: A. triphyllum L. Schott (jack-in-the-pulpit) Plant extends from a starch-rich corm. Leaves situated at the end of two long petioles. Leaves are sessile to elliptic in shape. Peduncle is shorter than petiole and the spathe is 4–7 inches long and often green to purple on outside. Blade bent forward, spadix nearly cyclindric, and the berries are red (Hortorium 1976). Usage: Early Europeans noted that Native peoples produced a poultice or a decoction from the corm. This preparation was used for treating boils or washing sore eyes (Densmore 1974; Hamel and Chiltoskey 1975). Description of Starch: Assemblage (corm) primarily comprised single bell- and dome-shaped grains. Grains range in size from 5–22 µm, with an average grain size of 13.4 × 12.4 µm. Stellate fissures are common. Hila in an eccentric to semi-eccentric position. One to two indented facets common on dorsal side. Hila are generally open. Lamellae are seldom witnessed. Birefringence well defined. Arms tend to curve or flare out distally following the shape of the grain.

Figure: Arisaema triphyllum.

Distribution: http://plants.usda.gov/java/profile?symbol=ARTR. Summary: Arisaema triphyllum Starch is abundant in corms. The flared bell forms with stellate fissures and semi-eccentric hila are of taxonomic value. Starch from A. triphyllum berries awaits analysis. Works Cited: Crow, G., and C. B.

Family: Araliaceae Genus: Aralia Species: A. nudicaulis L. (wild sarsaparilla) Perennial that grows approximately 1 foot in height extending from a rhizome. Leaves are two to three pinnate, with two to three leaflets on each pinna that appear elliptic to lanceolate and are up to 6 inches in length, finely serrate with umbels up to 7 inches (Hortorium 1976). Usage: The root of this species is widely represented within the literature on historic Native plant use. In all instances, people processed the roots for medicinal purposes. Historic Algonquians used an infusion of the root to treat kidney disorders (Black 1980). Other people throughout the Eastern Woodlands prepared poultices and decoctions of mashed root for stomach pain, sores, nosebleeds, and sore eyes (Densmore 1974; Herrick 1977; Leighton 1985; Tantaquidgeon 1972). Description of Starch: Assemblage (roots) primarily comprised single to compound polygonal grains and granules. Granules generally range in size from 2–6.25 µm and have an average size of 5.8 × 4.64 µm. Edges tend to be angular. Hila are positioned centrically (an uncommon trait within starch derived from subterranean storage organs). Hila also tend to be open. Fissures uncommon, as are lamellae.

Figure: Aralia nudicaulis. Scale bar equals 10 µm.

Distribution: http://plants.usda.gov/java/profile?symbol=ARNU2.

Species: A. racemosa (American spikenard) Flowers in June–July. Herbaceous perennial that often reaches 2 m in height. Leaves are large and twice compound. Leaflets are ovate in shape and serrated. Inflorescence is large terminal panicles, fruit purple. Prefer rich woods (Rhoads and Block 2000). Usage: Historic Native groups of the Eastern Woodlands used the root of A. racemosa for a variety of medicinal purposes. The majority of the accounts describe the preparation of poultices, decoctions, and infusions of mashed roots. The ointment was then applied externally to treat boils, strained muscles, and fractured bones (Densmore 1974; Gilmore 1933; Herrick 1977). Some peoples used infusions for severe ailments such as tuberculosis and kidney problems (Mechling 1959; Speck 1917). Description of Starch: Assemblage (rhizome) primarily comprised single and compound grains consisting of few granules. Forms tend to be polygonal to subangular in shape. These grains range in size from 2–10 µm, with an average size of 7 × 6.5 µm. Surfaces can be occasionally wavy. Hila tend to be centric, an uncommon trait for starch derived from subterranean storage organs. Birefringence well pronounced. Arms tend to be straight and cross through the centric hilum, which is generally open.

Figure: Aralia racemosa.

Genus: Panax Species: P. quinquefolius (American ginseng) Flowers in May; fruit in September–October. Herbaceous plant of approximately 60 cm in size. Leaves composed of five oblong to ovate leaflets, with long petiole; flowers greenish, fruit red, approximately 1 cm in size. Prefers mesic wooded environments; formerly frequent but declining due to collecting (Rhoads and Block 2000). Usage: Historic Eastern Woodlands Native peoples widely incorporated the roots of P. quinquefolius into their pharmacology. People prepared compounds and infusions with the root for treating vomiting, tapeworms, and tuberculosis (Herrick 1977; Speck 1941). Tantaquidgeon (1972) notes that ginseng root was used when all other remedies had failed. Description of Starch: Assemblage (rhizome) primarily comprised single spheres and domes. Compound grains consist of approximately three bell- to dome-shaped granules. Forms tend to be subrounded and slightly irregular. Grains range in size from 3–12.5 µm, with an average size of 8.26 × 8.01 µm. Darkened surface features can be witnessed on many. Hila are semi-eccentric to centric. Birefringence well defined and the arms of the cross bend slightly.

Figure: Panax quinquefolius.

Distribution: http://plants.usda.gov/java/profile?symbol=PAQU.

Species: P. trifolius (dwarf ginseng) Flowers in later April–early May. Herbaceous plant growing to approximately 20 cm in height. Leaf composed of three lanceolate to elliptic leaflets, each approximately 4–8 cm long; flowers white and fruit yellow. Plant prefers moist woods (Rhoads and Block 2000). Usage: Many historic Native groups reportedly used the roots of P. trifolius to treat ailments of the chest (Hamel and Chiltoskey 1975; Herrick 1977; Taylor 1940). Known preparations of this root are sparse. Roots were generally chewed or taken as an infusion. Description of Starch: Assemblage (rhizome) primarily comprised single (simple) domes and bells. Grains range in size from 3–10 µm, with an average size of 9.3 × 8.99 µm. Hila are positioned eccentrically and initial to transverse fissures are common. No lamellae were witnessed. Birefringence well defined and arms cross through the eccentric hila that generally tend to be open.

Figure: Panax trifolius.

Distribution: http://plants.usda.gov/java/profile?symbol=PATR2.

Summary: Araliaceae Starch production in this family varies among taxa. A.

nudicaulis starch, for instance, occurs infrequently within the rhizomes and the starch witnessed is of poor taxonomic value. Starch is abundant in the genus Panax. Many of the forms present in these taxa are of limited taxonomic value. P. trifolius, however, does produce morphotypes indicative of this taxon.

These tend to be the truncated elliptical bell forms with V-shaped fissures. Works Cited: Black, M. J. 1980 Algonquin Ethnobotany: An Interpretation of Aboriginal

Leaves hairy and extend from a rhizome; flower also extends via a petiole from rhizome. Plant prefers rich woods and wooded floodplains (Rhoads and Block 2000). Usage: Rhizome used for a variety of medicinal purposes. Some historic Native groups prepared an infusion or decoction for treating colds, fevers, worms, flux, and tuberculosis (Black 1980; Densmore 1974; Hamel and Chiltoskey 1975; Herrick 1977). Densmore (1974) also mentions that the rhizome was cooked with food to aid in digestion. Description of Starch: Assemblage (rhizome) primarily comprised single (simple) dome-shaped grains and compound grains composed of granules exhibiting three to four facets on the distal surfaces. Grains range in size from 2–13 µm, with an average size of 8.7 ´ 8.5 µm. Hila are usually open and tend to be semi-eccentric. Initial fissures were witnessed, although lamellae were not.

Family: Asclepiadaceae Genus: Asclepia (milkweed) Flowers in the months of June–July. Perennial herbs, usually growing to an approximate height of 75 cm. Leaves are whorled and the corolla is deeply divided. These plants also tend to have five horns within, or extending from, the hoods (Rhoads and Block 2000). Usage: The many species of milkweed served just as many purposes within historic Native economies throughout North America. Ethnobotanical studies note the usefulness of the inner bark for making cordage (Merriam 1966; Powers 1874). Researchers also note the use of pounded roots for treating ailments such as epileptic fits (Tantaquidgeon 1972) and kidney problems (Swanton 1928; Taylor 1940). Description of Starch: Assemblage (root) primarily comprised single (simple) and small compound grains. Compound grains composed of four to seven polygonal granules. Single grains range in size from 2–9 µm, with an average size of 7 × 5.6 µm. These appear as bell- and dome-shaped forms, although ovate and oblong morphologies also occur in smaller frequencies. These forms also tend to have two visible concentric lamellae. Hila tend to be slightly semi-eccentric. Birefringence well pronounced and the arms tend to curve centrally in many forms.

Family: Berberidaceae Genus: Podophyllum Species: P. peltatum (mayapple) Flowers in May. These herbaceous perennials spread/ascend from rhizomes and usually occur in patches, especially in mesic wooded areas. The serrated leaves tend to be alternate and simple with deep lobes. A single white flower forms beneath the leaves on a petiole from which a 4–5 cm ovoid yellow berry later extends (Rhoads and Block 2000). Usage: Historic Native peoples reportedly utilized both the berry and the root of this plant. The Iroquois are said to have eaten the mature fruit raw. These accounts also describe the Iroquois preparing a cake of the mashed berries. The cakes were dried and stored for future use (Waugh 1916). Historic Native peoples ground or powdered the root for use against ulcers and sores or for constipation (as a purgative/laxative) (Hamel and Chiltoskey 1975; Herrick 1977; Tantaquidgeon 1972). Herrick (1977) also notes that the plant can be toxic. Description of Starch: Assemblage (rhizome) comprised single (simple and cluster) spheres and oval-shaped forms. Subangular polygons also present. Grains range in size from 3–9 µm, with an average size of 7.35 × 6.8 µm. Birefringence is well defined. Slightly curved arms cross through the hilum, which is generally closed.

Family: Brassicaceae Genus: Cardamine (formerly Dentaria) Species: C. concatenata Michx. (formerly laciniata) (cutleaf toothwort) Flowers in May. Perennial plants rising from rhizomes. Leaves are whorled and tend to be deeply palmately three-lobed. Inflorescences have three white or purple flowers and fruit measuring 1–2 cm. Prefers deciduous woods, where it is common (Rhoads and Block 2000). Usage: Most references for this plant pertain to the Iroquois. They reportedly prepared a poultice of mashed rhizomes that was used for treating headaches (Herrick 1977). Rhizomes were also used to treat heart palpitations or heart disease. Herrick further describes how the Iroquois men would carry segments of rhizome around to attract women. Waugh (1916) also notes that it was eaten with no preparation. Description of Starch: Assemblage (rhizome) primarily comprised single (simple) oval to elliptic/cuneate and often “tailed”/acuminate forms. These grains range in size from 4–15 µm, with an average size of 11.5 × 8 µm. Hila are positioned eccentrically and generally appear open. Fissuring is uncommon, but initial fissures are present. Lamellae not witnessed. Birefringence well defined and arms tend to be distorted or “wrinkled.”

Family: Caprifoliaceae Genus: Lonicera Species: L. canadensis Bartr. (American fly honeysuckle) Flowers in May and fruits in June–July. Perennial shrub growing to approximately 2 m in height. Leaves are triangular—ovate to oblong and slightly glabrous—corolla yellow and spurred at base. Fruit is red. Plant prefers cool moist woods (Rhoads and Block 2000). Usage: The root of this species does not appear in ethnobotanical literature. Historic Native peoples did use other tissue for medicinal purposes. The bark and shoots are each noted as being used for urinary disease, syphilis, and gonorrhea (Smith 1923, 1933; Speck 1917). Description of Starch: Assemblage (root) primarily comprised single bells, domes, and irregular forms. Grains range in size from 3–10 µm, with a mean size of 7 × 6.3 µm. Hila positioned eccentrically to semi-eccentrically. Birefringence is well defined and the arms of the cross vary from highly irregular and curved to straight.

Family: Chenopodiaceae Genus: Chenopodium Species: C. berlandieri Moq. (goosefoot) Branched, erect annual that grows to 1 m in height. Leaves toothed, whitish, and lanceolate to ovate in shape. Dense clusters of flowers that form spikes grouped in terminal panicles. Sepals winged, fruit wall reticulate (Rhoads and Block 2000). Usage: C. berlandieri has a long history of interaction with Native peoples in the Eastern Woodlands. Early evidence of domesticated C. berlandieri has been documented at the Cloudsplitter site in Kentucky and the Riverton site in Illinois from ~3800 B.P. (Smith and Cowan 1987; Smith and Yarnell 2009). The cultivation of this starchy grain fell from popularity sometime prior to European colonization. Description of Starch: Assemblage (seed) comprised spherical to oval-shaped compound grains composed of numerous rhomboid-shaped granules. Granules tend to be consistently <2 µm in size. Hilum appears to be centric. Chenopodium spp. starch can be recognized by its consistent size and shape combined with a lack of visible extinction cross in compound grains.

Family: Cyperaceae Genus: Cyperus Species: C. esculentus L. (yellow nutsedge) Rhoads and Block (2000) describe this plant as a perennial extending from slender rhizomes that end in small tubers; plant can grow upward to approximately 70 cm in height. Leaves extend from the base of the plant. Inflorescence consists of several rays, often branched at the top. Usage: Bocek (1984) notes that historic Native peoples of California ate the tubers, while Fowler (1990) describes a preparation among the Northern Paiute of western Nevada involving drying, grinding, and mixing with other foods. Description of Starch: Assemblage (tuber) comprised single and compound grains. Single grains tend to be spherical. Compound grains range from ovals and spheres to amorphous shapes. These grains range in size from 7—25 µm, with an average size of 17 × 13 µm. Concentric lamellae are visible but faint. Darkened central areas are common, probably due to depressions. Birefringence is usually obscured through this area. Hila are position centrically. No fissures present.

Rhoads and Block (2000) describe this plant as a climbing herbaceous vine, up to 5 m in height, growing from a stout rhizome. Leaves alternate, cordate-ovate with 7–11 veins. Usage: Smith (1928) notes that the root of this plant was given to women to alleviate pain during childbirth. Description of Starch: Assemblage primarily comprised single elongate to triangle forms and elongate oval grains ranging in size from 10–25 µm, with an average size of 15.2 × 10.6 µm.

Family: Fabaceae Genus: Amphicarpaea Species: A. bracteata L. (hogpeanut) Flowers in late May to early September. Slender annual vine growing to approximately 1.5 m, flowers forming along a raceme, calx slightly irregular, fruit flat with three seeds. A petal-less flower develops a subterranean one-seeded fruit at the end of a slender peduncle in the lower portion of the stem (Rhoads and Block 2000). Usage: Gilmore (1919) notes that Native peoples in the Missouri River region used the beans as a food resource. The subterranean fruit occurs more frequently in the literature. Field mice are said to gather and store these fruits. Native peoples raided mouse caches, thus procuring large numbers in a relatively short time (Fletcher and La Flesche 1911; Smith 1928). Fruits were often stored for winter use, which involved first peeling and then boiling them (Densmore 1974; Fletcher and La Flesche 1911). Description of Starch (two assemblages): Assemblage (seed) primarily comprised single (simple) oval to spherical forms ranging in size from 5–13 µm, with an average size of 8.95 × 7.55 µm. Hila are semi-eccentric to eccentric. Surfaces slightly undulating, fissures uncommon, although initial fissuring is present. Birefringence well defined and the arms tend to appear wavy due to surface texture.

Figure: Amphicarpaea bracteata (seed).

Assemblage from the subterranean seed primarily comprised single (simple) elongated ovals, elliptical to conic and ovoid forms.

Some exhibit flattened distal margins or attachment scars. Grains range in size from 7–39 µm, with an average size of 22 × 14 µm. Grains are usually half as wide as long. Forms thicken toward the eccentric hilum and taper distally. Dome-shaped forms also present. The majority of the grains exhibit a crescent-shaped feature above, or in replace of, the hilum. Concentric lamellae are slightly visible in a small percentage of the assemblage. Birefringence well defined (Reichert 1913:221).

Genus: Apios

Species: A. americana Medik. (groundnut) Flowers in late June to early September. Rhizomatous perennial vine, tuber producing, has three to seven leaflets and flowers in axillary racemes. The corolla tends to be purplish brown. The fruit, a linear bean, contains several seeds. After dehiscence, the valves coil (Rhoads and Block 2000). Usage: Historic Native peoples throughout much of the Eastern Woodlands reportedly used tubers of this plant for dietary purposes. Tubers were sometimes eaten raw, boiled, or roasted (Gilmore 1919). Tantaquidgeon (1972) describes these tubers as being dried, peeled, and ground into flour for making bread or to thicken soups. Smith (1923) notes that the tubers were peeled, parboiled, sliced, and dried for winter use. The Cherokee also used the beans for food (Hamel and Chiltoskey

1975). No medicinal references for A. americana were encountered. See Chapter 2 for more details. Description of Starch (two assemblages): Assemblage (seed) primarily comprised spherical, poorly fused compound grains consisting of many spherical to slightly polygonal granules and oval to ovate single grains. Granules measure approximately 2–3 µm in size. Hila tend to be centric. Birefringence well defined and arms are straight.

Figure: Apios americana (seed).

Assemblage from the tuber primarily comprised single oval, elliptical, and ovate to cone-shaped forms (although Reichert 1913:219 also describes compound forms composed of two to four parts). Grains range in size from 6–30 µm, with an average size of 15 × 9 µm and a mean size of 12 µm. Hila are open and tend to be eccentric to semi-eccentric or, as Reichert (1913:219) notes, “one third to one seventh eccentric.” Longitudinal fissures are common—lamellae are not. Grains appear rounded and generally asymmetrical without depressions, except where fissuring has resulted in a severe depressed canyonlike surface. Grains are slightly compressed in profile. Birefringence well defined and arms are generally wavy and can be distorted.

Genus: Astragalus

Species: A. canadensis L. (Canadian milkvetch) Flowers in late June to early August. Rhizomatous perennial herb with erect stems growing to 1.5 m. Fruits nearly rounded and divided longitudinally, creating two locules (Rhoads and Block 2000). Usage: Several researchers note the use of A. canadensis roots for the treatment of ailments (Gilmore 1913; Rogers 1980). Hellson (1974) even describes the roots as a staple of the Blackfoot people. Only one reference mentions the use of seeds and in this instance they were used as food for horses (Rogers 1980). Description of Starch: Assemblage (seed) primarily comprised single (often clusters) oval to ovate forms. These grains range in size from 2–6 µm. Birefringence is weak; often an extinction cross cannot be distinguished, rather a darkened spot forms in the center of the grain. Hilum is positioned centrically. Fissures and lamellae not witnessed.

Genus: Phaseolus Species: P. polystachios L. B.S.P. (thicket or wild bean)

Flowers in July to September. Rhoads and Block (2000) describe this plant as a perennial herbaceous vine growing to 4 m in length. Plant has three leaves arranged pinnately, each ovate in shape and broad. Purple flowers arranged on a raceme, fruit flat, 3–6 cm, and coiling after dehiscence. Usage: No known ethnobotanical information. Description of Starch: Assemblage primarily comprised single (simple) grains. Grain shape ranges from oval to irregular oval to kidney. Grains range in size from 11–40 µm, with an average size of 16.57 × 23.35 µm. Several bold concentric lamellae are present and most become pronounced toward the outer margin. A single, often ragged, longitudinal fissure is present. Birefringence bold yet generally distorted medially.

Figure: Phaseolus polystachios.

Distribution: http://plants.usda.gov/java/profile?symbol=PHPO2. Species: P. vulgaris L. (common bean) Usage: As noted in Chapter 2, beans appear within the archaeological record of the Middle Atlantic and Northeast regions after approximately A.D. 1300 (Hart et al. 2002). This tropical domesticate is widely cited within ethnohistoric accounts of the Middle Atlantic region (Aller 1954; Hariot 2007 [1590]). Description of Starch: Assemblage primarily comprised single (simple) oval/irregular oval and kidney-shaped grains. Grains range in size from 11–38 µm and average 15.6 × 22.3 µm. A longitudinal and often ragged cleft fissure, a characteristic of this genus, is present within 80–90 percent of the population. Bold concentric lamellae highly visible and extend from the margin almost to the hilum (which is centric yet obscured due to fissuring). Birefringence is well pronounced though it is often distorted in the central area of the kidney-shaped grains.

Distribution: Cultivated.

Genus: Pediomelum (formerly Psoralea) Species: P. esculentum (formerly esculenta) (Pursh) Rydb.

(Indian breadroot)

Usage: The starch-rich taproot of this plant occurs within many ethnobotanical studies pertaining to Native subsistence and pharmacopoeia (Hart 1981; Hellson 1974). While this plant's main range of distribution is confined to the central portion of North America, Harris (1891) reports its presence in New York State. The USDA Plants Database also includes New York in the distribution of the species (see below). Description of Starch: Assemblage primarily comprised single and compound grains and granules. Polygonal forms occur with the greatest frequency, followed by bells (2–3 facets) and domes (1–2 facets). Lamellae not noticed. Fissures visible; these tend to be “initial” to transverse in shape. Hila are semi-eccentric within the bells and domes, while within polygonal forms the hilum is centric. Birefringence is well defined and arms tend to be straight, giving the appearance of a perfect X shape.

Genus: Strophostyles Species: S. helvola L. (amberique-bean) Flowers in July to September. Annual. Rhoads and Block (2000:419) describe this plant as a trailing vine growing to approximately 1 m in length, with trifoliate leaves, commonly with one to two lateral lobes, several flowers on long peduncles, pink to purple flower with 4– to 9-cm fruit. Usage: Ethnobotanical studies conducted in Louisiana describe the bean of this species as being used for medicinal purposes among the Houma Indians (Speck 1941). Other groups in Louisiana also mashed the root for dietary purposes (Bushnell 1909). Description of Starch: Assemblage (bean) primarily comprised single (simple) oval to kidney-shaped grains. These range in size from 15–35 µm, with an average size of 18 × 20 µm. Thick concentric lamellae are common, as is a longitudinal cleft fissure often appearing ragged. Birefringence well defined except in overlapping fissures, where it often appears distorted.

Summary: Fabaceae This family consists of many important economic taxa. All of the species studied with the exception of Astragalus sp. produce large quantities of starch within the seeds and, in several instances, the subterranean storage organs. Many of these taxa also produce starch types of taxonomic value. In Phaseolus, the oval to kidney-shaped grains with bold concentric lamellae and a longitudinal cleft fissure are diagnostic. A similar form is present in Strophostyles, only the lamellae are approximately two times wider and are spaced farther apart than in Phaseolus. The tubers and subterranean fruit of Apios and Amphicarpaea both produce readily identifiable morphotypes in their subterranean organs. Starch derived from Apios fruit is of poor taxonomic value. The surface texture present on the globose Amphicarpaea fruit starch is indicative of this taxon. Further attention to the taxonomic value of Psoralea starch is needed.

Fabaceae Bean Starch As noted above, several taxa produce taxonomically valuable

bean starch. Domesticated beans (Phaseolus vulgaris), for instance, exhibit a distinctive morphology useful for differentiating it from closely related taxa. These single oval to kidney-shaped grains range in size from 14–45 µm and appear laminated with well-pronounced concentric lamellae and a large ragged longitudinal/mesial cleft fissure often extending the length of the grain (Perry 2001:135; Piperno and Holst 1998:775; Reichert 1913). Phaseolus lamellae tend to be fine and tightly spaced. The lamellae are taxonomically valuable for

distinguishing P. vulgaris from P. polystachios (wild bean). Within P. vulgaris, visible lamellae generally extend from the outer margin inward to the centric hilum, while P. polystachios has visible lamallae at the outer margin; they rarely extend beyond the longitudinal fissure. This arrangement often results in fewer lamella on average in P. polystachios in comparison to P. vulgaris.

Strophostyles helvola (amberique-bean) starch also exhibits oval to kidney-shaped laminated forms with longitudinal cleft fissures and grains overlapping in size with Phaseolus spp. Starch produced by this leguminous plant differs from those studied in Phaseolus spp. based upon the size and arrangement of its concentric lamellae. Where the concentric lamellae of Phaseolus tend to be fine and tightly spaced, those of Strophostyles helvola tend to be thicker (1.5–2 times thicker) and spaced farther apart (2×) than those witnessed in Phaseolus spp. Works Cited: Aller, W.

Family: Fagaceae Genus: Castanea Species: C. dentata (formerly americana) (American chestnut)

Rhoads and Block (2000:424) describe this tree as formerly much taller than the height reached today (~5 m). Leaves toothed and lanceolate in shape with an acuminate distal end. Nuts usually two to four per bur. Prefers dry woods. Usage: Historic Native peoples throughout the Eastern Woodlands reportedly targeted the nuts for subsistence purposes (Hamel and Chiltoskey 1975; Parker 1910; Perry 1975; Waugh 1916). Description of Starch: Assemblage primarily comprised single (simple) elliptical, oval, to ovoid grains. Compound grains (2–3 granules) also present in smaller frequencies. Grains range in size from 3–20 µm, with an average size of 12 × 8 µm. A single, straight longitudinal fissure is occasionally present. The hilum is centric to semi-eccentric and closed. Reichert (1913:430) notes the presence of “well marked facets.” Birefringence well defined; however, in some grains the arms become wavy across the central portion. No lamellae witnessed.

Genus: Quercus Species: Q. alba (white oak)

Rhoads and Block (2000:427) describe this tree as reaching ~30 m in height. Leaves have 5–11 rounded lobes. Acorns are ~1.5–3 cm in length and 1/4 to 1/3 is covered by a warty, bowl-shaped cup. Prefers dry to moist woods. Hybridizes with Q. bicolor, Q. macrocarpa, and Q. montana. Usage: Native peoples throughout much of the temperate world exploited acorns for subsistence purposes (Mason 1992). As Chapter 2 describes in greater detail, acorns of the red oak group contain high concentrations of tannic acid in comparison to the white oak group. Chapter 4 describes processing procedures utilized by Native peoples in California to eliminate the tannic content in acorns. Description of Starch: Assemblage primarily comprised single (simple) well-rounded ovoid, ellipsoidal, to elongated wedgelike forms. Also present are smaller spherical grains. Assemblage ranges in size from 5–20 µm, with an average grain size of 14 × 10 µm. Longitudinal fissure present. Birefringence well defined; arms curve inward and meet at the centric to semi-eccentric hilum unless a deeply incised fissure is present. No lamellae witnessed. Reichert (1913:421) describes the presence of “wart-like” projections at one or more points.

Summary: Fagaceae Propagules of Fagaceae produce large amounts of starch. Since hybridization is known to occur within Quercus, starch grains may serve little utility in differentiating between species of this genus. There is, however, a correlation between grain size and group division (white vs. red) in Quercus, with species of white oak producing significantly larger grains than those of the red oak group (see below for further details). Castanea dentata’s oval to ovoid, subrounded grains lacking longitudinal fissures are also of taxonomic value.

Fagaceae—The Beech Family/Oak Acorns (Quercus spp.) The genus Quercus is divided into three groups: red oak

(section Lobatae), white oak (section Quercus), and an intermediate group (section Protobalanus). These classifications are primarily arranged based upon phenotypic similarities between species (Rhoads and Block 2000). For instance, Johnson (2002:10) describes how the interior of the red oak acorn shells are hairy (tomentose), while those of the white oaks lack hair (or are glabrous). The intermediate category exhibits variability between species and therefore this characteristic is unreliable for differentiation. Oak leaves can also be used to classify species according to group. Those of the red oaks tend to have toothed lobes, while white oak lobes lack teeth. Level of tannic acid also differs between groups, with white oaks producing little to no tannins while the red oaks maintain high concentrations (Mason 1992; Scarry 2003). In spite of extensive

phenotypic variability, members of Quercus have very little genetic diversity (Johnson et al. 2002). As a result, gene flow often occurs within sympatric stands, causing hybridization (Howard et al. 1997). Whittemore and Schaal (1991) explain that many of these crosses result in infertile offspring, though the potential for backcrossing remains incompletely understood. In spite of this, researchers put forth that naturally occurring hybrids are rare and when present usually only consist of scattered F1 individuals (Whittemore and Schaal 1991:2540).

The aforementioned group divisions are a widely accepted form of taxonomic classification (Johnson et al. 2002). Starch grain morphology can also be useful for establishing group-level taxonomic identifications. The following reports on the analysis of 13 different species of Quercus native to eastern North America and highlights the morphological distinctions between the red and white oak groups.

The overall size of Quercus starch varies depending upon group division. Figure 1 demonstrates that grains from the white oak group tend to be significantly larger than those of the red oak group, with only species of the white oak group having grains >17 µm in length. Small grains are equally represented in most populations. Red oaks, however, tend to consistently produce smaller grains than the white oak group. As Figure 1 also illustrates, grains ranging from 12.5–15 µm in size could potentially derive from either group (although the white oak group generally contains the greatest number of taxa falling in the 15-µm range). In this instance, additional morphological characteristics are needed for distinguishing between taxa. Two species from within the red oak group, Q. coccinea (scarlet oak) and Q. palustris (pin oak), produce starch grains with a distinctive V-shaped fissure emanating from the hilum. Morphological attributes, such as fissure type, in conjunction with size offer the ability to refine and secure group level identifications.

Castanea dentata (American chestnut) also belongs to the Beech family. Their similar starch grain assemblages suggest the evolutionary relationship between Castanea and Quercus. The same basic irregular elliptical/oval to wedge-shaped grains dominate both assemblages. C. dentata also overlaps with Quercus in size. Distinctions do occur between these two genera. The longitudinal fissure, which tends to be conspicuous in many Quercus taxa, is only occasionally present in C. dentata.

Figure 1: The correlation between size (length in microns) of Quercus starch in relation to taxonomy. Taxa included in lower dashed oval belong to the red oak group, while those included in the upper oval belong to the white oak group.

Additionally, C. dentata occasionally produces compound grains (Reichert 1913:43). These consist of two to three granules and take on a form consistent with that of other single grain types in the assemblage. In cross-polarized light, each individual granule becomes visible, sometimes producing multiple extinction crosses or, if obscured, wavy irregular extinction crosses. This trait was not noticed in any of the Quercus species studied as part of this research and is useful for distinguishing between these two genera.

Summary: Liliaceae Many taxa within this family produce high levels of starch within their subterranean storage organs. There are also a significant number of species within this family that produce other forms of carbohydrate energy reserves instead of starch, e.g., inulin (Wandsnider 1997). The starch assemblages from the taxa studied here are of taxonomic value. Lilium can be distinguished from Erythronium based upon the length of the distal portion in pyriform-shaped grains. Those of Lilium tend to be of greater length than those of Erythronium. Starch forms witnessed in Trillium erectum tend to occur in many unrelated species and are therefore of low taxonomic value.

Liliaceae—Lilium vs. Erythronium Pyriform grains are a common form present within many species composing both Erythronium and Lilium. The pyriform description denotes a single grain that has a thicker and often rounded distal end that tapers proximally. Although both Erythronium and Lilium share this same basic trait (possibly demonstrating their shared evolutionary history), distinctions are present that can be used to establish a higher taxonomic resolution.

Figure 2: Measurement used to differentiate between Lilium sp. and Erythronium sp. pyriform shape/conic forms. (A) Variation in pyriforms present in Lilium sp.; (B) three different pyrifrom/conic forms present in Erythronium sp. Dotted lines indicate location of shoulders.

As Figure 2 demonstrates, Lilium sp. and Erythronium sp. produce pyriform-shaped forms that vary in morphology in specific ways. To distinguish them, imagine a line connecting the two widest points of the grain, here referred to as the shoulders, and note the distance between this line and the distal end. This distance tends to be qualitatively greater in taxa belonging to Lilium as compared to Erythronium. Pyriform-shape grains from six species (three from each genus) exhibit characteristics consistent with this configuration. It should be stressed that this is not a universal attribute present throughout the entire assemblage. For instance, this trait does not apply to flabellate-shaped and spherical grains that are also present within these assemblages. Works Cited: Black, M. J.

Family: Nelumbonaceae Genus: Nelumbo Species: N. lutea (American lotus) Rhoads and Block (2000:10) describe the leaves of this aquatic plant as ranging in size from 30–70 cm. Leaves extend above the water on long petioles. Long peduncles also rise above the water surface where a pale yellow flower emerges (15–25 cm). A mature woody receptacle (10 cm across) holds individually stored fruits (1 cm in size). Usage: N. lutea tubers were reportedly peeled or boiled as part of their culinary preparation (Gilmore 1919; Smith 1933). Other accounts describe the seeds as being used for dietary purposes (Gilmore 1919; Smith 1928, 1932). See Chapter 2 for further discussion.

Dome-shaped granules also present but in the minority. Grains range in size from 7–28 µm, with an average size of 21 × 17 µm. Grains appear uniform in three dimensions. Offset, simple (initial) fissures originating at the hilum commonly occurring. Flattening is present on the distal surface due to packing. Concentric lamellae are common (concentrated in distal region of grain), as are vague traces of birefringence even when viewed without polarized light. Converging lines common in dome forms.

Figure: Nelumbo lutea (tuber).

Assemblage (seed) composed of single (simple) ovoid to irregular oval-shaped grains. These grains range in size from 7–16 µm and have an average size of 13.35 × 12 µm. Hila centric and often closed. Concentric lamellae present and often appear raised. Longitudinal fissures present. Birefringence well defined and occasionally arms take on a dumbbell-like appearance.

Figure: Nelumbo lutea (seed).

Distribution: http://plants.usda.gov/java/profile?symbol=NELU.

Summary: Nelumbo lutea Starch is widely occurring within both the tubers and seeds of this species, at least on a seasonal basis. Nelumbo lutea tuber starch is taxonomically valuable, specifically, the rounded elliptical forms with slight concentric lamellae visible in the most distal segment of the grain. Starch produced within the seeds is also taxonomically valuable. The basic form, oval to irregular oval, is common in many unrelated taxa; however, the presence of lamellae is only noted in N. lutea seeds. Works Cited: Gilmore, M.

Family: Nymphaeaceae Genus: Nuphar Species: N. lutea L. (yellow pond-lily) Rhoads and Block (2000:511–512) describe this aquatic plant as having large ovate leaves (5–40 cm), yellow flowers, and ovoid fruits. Plant prefers lake margins, ponds, slow-moving streams, swamps, and tidal marshes. Usage: Ethnobotanical studies discuss the use of N. lutea rhizomes for treating a wide range of ailments (Herrick 1977; Smith 1923, 1932; Speck 1917). People also reportedly used these rhizomes for dietary purposes (Rogers 1980). See Chapters 2 and 4 for further discussion. Description of Starch: Assemblage (rhizome) comprised single spherical grains with two to three flat surfaces on the distal margin. Compound grains also present within the assemblage. Grains range in size from 7–22 µm, with an average grain size of 14 × 14 µm. Fissures present, and these tend to be transverse, Y-shaped, or stellate types. Concentric lamellae present; often a single bold lamella encircles the fissure. Birefringence is well pronounced and arms cross straight through the centric to semi-eccentric hilum.

Figure: Nuphar lutea (rhizome).

Description of Starch: Assemblage (seeds) comprised compound oval to spherical grains often consisting of hundreds of small (2–2.5 µm) oval to spherical granules. Hilum is centric and appears as a dark central spot.

Figure: Nuphar lutea (seed).

Distribution: http://plants.usda.gov/java/profile?symbol=NULU. Genus: Nymphaea Species: N. odorata (American white waterlily) Rhoads and Block (2000) describe the leaves of this aquatic plant as rounded to elliptical with a narrow sinus at the base. Flowers are white to pink (rare), fragrant; fruit depressed and globose, maturing underwater; grows in lakes and ponds. Usage: The rhizomes of this plant appear widely within the ethnobotanical literature. Several researchers note the use of this taxon for medicinal purposes (Densmore 1974; Smith 1932; Speck 1917; Turner et al. 1980). Others describe Native people using the rhizomes for dietary purposes (Rogers 1980; Vestal and Schultes 1939). Description of Starch: Assemblage (rhizome) comprised single (simple) oval to ovate slightly expanding (conic) forms. Domes/hemispherical forms with one facet and often a V-shaped fissure are also present in the assemblage. Grains range in size from 10–45 µm, with an average size of 29 × 22 µm and a mean size of 25 µm. Grains tend to be rounded to subrounded and regular, although flattening along segments of the distal end caused by packing witnessed. In profile, grains tend to be narrow and slightly tapered. Hila are eccentric and largely open. The greatest degree of fissuring within the assemblage consists of initial followed by transverse types, although most fail to exhibit any evidence of fissuring. When viewed without cross-polarized light, evidence of an extinction cross remains present in a large portion of the assemblage. Birefringence usually

consists of straight arms intersecting at the hilum. Concentric lamellae witnessed throughout assemblage.

Figure: Nymphaea odorata.

Distribution: http://plants.usda.gov/java/profile?symbol=NYOD. Summary: Nymphaeaceae Starch is produced in large quantities, at least seasonally, within these taxa. The conic forms produced within the rhizomes of N. odorata that expand distally and exhibit traces of birefringence even when viewed without polarized light are taxonomically valuable. In Nuphar lutea rhizomes, the spherical grains with one to two facets, stellate fissures, and often lamellae are also taxonomically valuable. Starch produced by the seeds of N. lutea is also significant. These consist of compound grains composed of spherical granules that measure consistently 2 µm in size with well-defined birefringence.

Family: Papaveraceae Genus: Sanguinaria Species: S. canadensis L. (bloodroot) Rhoads and Block (2000:532) describe this plant as reaching between 5 and 15 cm in height. Plant has one solitary leaf, often with three lobes. Stem and flower (white) arise from a rhizome that contains orange-colored juice. Prefers rich woods and roadsides. Usage: Rhizomes of S. canadensis frequently occur within ethnobotanical studies. Many authors report the use of these roots for medicinal purposes (Densmore 1974; Herrick 1977; Smith 1928; Tantaquidgeon 1972). One study also discusses its use for consumption purposes (Mechling 1959). Description of Starch: Assemblage (rhizome) comprised single (simple) grains and clusters of globose, bell, and dome shapes. The most common forms have two to three facets. These grains have a semi-eccentric hilum, often with one lamella positioned just inside the margin. A “cap” is present on the distal surface. Fissures rare but when present appear as the initial transverse type (Reichert 1913:239).

Figure: Sanguinaria canadensis (rhizome).

Distribution: http://plants.usda.gov/java/profile?symbol=SACA13.

Summary: Sanguinaria canadensis Starch is widely produced within the rhizomes of this taxon, at least on a seasonal basis. Starch studied in this

taxon is also of taxonomic value, particularly the symmetrical globose shapes and bells with one to two facets on the distal surface that also exhibit a “capped” feature. Works Cited: Densmore, F. 1974 How Indians Use Wild Plants for Food, Medicine and

Introduction

This section details starch grain morphology as it relates to taxonomy within the grass family (Poaceae). A generalized description of each taxon is provided (data used for this segment of the supplementary materials are taken from the source referenced after each description). This is followed by a brief discussion of each specimen’s economic utility as portrayed in either the ethnobotanical or the archaeological record. Next, the starch assemblage for the specific organ in question is provided, in addition to a link to the USDA Plants Database, which provides images of the plant as well as its current distribution (U.S. Department of Agriculture, Natural Resources Conservation Service [USDA NRCS] 2008).

The following section includes 5 subfamilies and 10 tribes. These taxa are: from Arundinoideae, Centotheceae; from Bambusoideae, Oryzeae; from Chloridoideae, Cynodonteae and Eragrostideae; from Panicoideae, Andropogoneae and Paniceae; and from Pooideae, the tribes Aveneae, Bromeae, Meliceae, Poeae, Stipeae, and Triticeae. Forty-six different taxa were analyzed from within these tribes. Species included in this study were chosen based on their representation in the ethnographic literature or among macrobotanical remains recovered from archaeological contexts. Noneconomic taxa composing the “natural” vegetation were also included. In addition, several Old World domesticates are present for comparative purposes.

Subfamily: Arundinoideae Tribe: Centotheceae Genus: Chasmanthium Five spp. of perennial grasses in east and southeast United States. Stems tend to be simple or branched, occurring in clusters rising from rhizomes. Leaf: blades flat, serrate; inflorescences paniculate, two spikelets, sometimes with many flowers. Laterally compressed, rachillas disarticulating above the glumes and between the florets (Hortorium 1976).

Species: C. latifolium (Michx.) H.O.Yates (sea-oats) [syn: Uniola latifolia Michx.]

Flowers from July to September. Occurring along stream banks and alluvial woods (Rhoads and Block 2000). Usage: The Yuman people of the southwest United States used the seeds of C. latifolium in gruel, or they were stored for later use (Castetter et al. 1951). Description of Starch: Assemblage comprised simple grains (single and clusters) exhibiting angular to subangular forms resulting from packing. Spherical, simple grains also occur in smaller frequencies. Fissuring is uncommon, but those present are only slightly pronounced. Grains are approximately 13 × 11.35 µm in size. Edges or margins of grains often appear slightly ragged. Hila are arranged centrically. Starch appears to be easily damaged by processing, often resulting in the distortion to elimination of birefringent properties.

Subfamily: Chloridoideae Tribe: Cyndonteae Genus: Bouteloua About 50 spp. of perennial or annual grasses from central United States to Argentina; spikes two to several; raceme on a common axis or sometimes solitary; spikelets few to many, rarely solitary; one flower, with rudiments of one or more florets above, sessile, in two rows along one side of the rachis, which is often naked at the tip (Hortorium 1976). Species: B. curtipendula (Michx.) Torr. (side-oats grama)

Flowers in August and September. Tends to prefer dry calcareous clearings and rocky and sandy sites, endangered in Pennsylvania (Rhoads and Block 2000). Described as a major warm-season species, grows in association with bluestems and is less drought resistant than blue grama (Alderson and Sharp 1995). Usage: Crawford and Smith (2003) describe the recovery of B. curtipendula from archaeological contexts in the Northeast. Ethnobotanical documents depict its usage as fodder among the Kiowa people (Vestal and Schultes 1939:14). Description of Starch: Assemblage primarily comprised small <5 µm single (simple and cluster) subrounded polygonal forms; spheres also occur in high frequencies. Hila arranged centrically. Fissures are uncommon.

Figure 2: Bouteloua curtipendula.

Distribution: http://plants.usda.gov/java/profile?symbol=BOCU.

Tribe: Eragrostideae Genus: Calamovilfa Approximately five spp. of perennial rhizomatous grasses. Culms 50–250 cm. Inflorescences composed of simple panicles that range in size from 8–80 cm. Spikelet has one floret, laterally compressed and unawned, disarticulating above the glume; achenes disperse with lemma and paleas. Glumes are subequal to equal. Fruit is an achene with pericarp free from seed (Thieret 2007).

Species: C. longifolia (Hook.) Scibn. (sandreed)

Native to the midwestern and western United States, warm-season, rhizomatous, perennial grass found on sandy soils, on prairies, and in open woods (Alderson and Sharp 1995). Described as planted and naturalized along beaches in Erie County, Pennsylvania (Rhoads and Block 2000:914). Usage: Rogers (1980) explains how the Sicangu people of South Dakota used the grass for utilitarian purposes such as pipe cleaners and charms. Description of Starch: Assemblage primarily comprised compound oval to spherical grains consisting of angular, often polygonal, granules. Angularity results from faceting. Individual granules average approximately 5.6 µm in size. Hila oriented centrically. Fissuring not noted. Surface appears smooth and generally featureless.

Figure 3: Calamovilfa longifolia.

Distribution: http://plants.usda.gov/java/profile?symbol=CALO.

Genus: Tridens Described as having culms that reach 10–15 dm in height, solitary or forming small tufts; blades range in size from 3–8 mm, panicles spreading or drooping and purplish in color, spikelets 5–10 mm long, disarticulating above the glumes and between the lemmas (Rhoads and Block 2000:983)

Species: T. flavus (L.) A. Hitchc. (purpletop) [syn: Triodia flava (L.) Smyth]

Flowers between July and September. Found in meadows, in old fields, and along roads (Rhoads and Block 2000:983). Usage: No known usage. Description of Starch: Assemblage primarily comprised polygonal to subangular irregular forms. Single and compound grains as well as clusters present. Starch from this assemblage has an average size of approximately 12.69 µm. Fissures are uncommon but when present appear only as shallow initial types. Grains appear angular and often exhibit sharp edges produced by well-defined facets. Surfaces often appear smooth, though ragged or wavy grains do occur with some frequency. No lamellae noted. Hila are arranged centrically and often are open. Birefringence well defined. Starch appears to be easily damaged by processing, often resulting in the distortion to elimination of birefringent properties.

Distribution: http://plants.usda.gov/java/profile?symbol=TRFL2.

Subfamily: Bambusoideae Tribe: Oryzeae Genus: Zizania Two or three spp. of tall, aquatic, annual or perennial grasses. Leaf blades flat, panicles large, terminal spikelets unisexual, one flower. Described as nearly cylindrical and disarticulating from the pedicel. The glumes tend to be obsolete and the female spikelet angled at maturity (Hortorium 1976).

Species: Z. aquatica L. (wild rice)

Flowers in late May to early September. Found in poorly drained/wetland environments, categorized as an obligate wetland species (Rhoads and Block 2000). Usage: Macrobotanical remains of Z. aquatica were isolated from sites in the Northeast and Middle Atlantic region (Crawford and Smith 2003; Hart and Asch Sidell 1996). Hart et al. (2003) also report the isolation of wild rice phytoliths from carbonized residues adhering to ceramic sherds in the Northeast. Many ethnobotanical accounts in the Midwest describe wild rice as a prized food source (Gilmore 1913, 1919; Reagan 1928; Smith 1923, 1928). Description of Starch: Assemblage primarily comprised compound grains consisting of hundreds to thousands of components. Individual granules <5 µm in size. Most appear slightly polygonal to subrounded. Hila arranged centrically. Fissures uncommon.

Distribution: http://plants.usda.gov/java/profile?symbol=ZIAQ.

Subfamily: Panicoideae Tribe: Andropogoneae Genus: Andropogon About 200 spp. of perennial grasses in warm and tropical regions of the world. Stems tend to be dense and are often coarse, grows in a dense mass. The inflorescences are compound, of few to many peduncled, sheathed racemes or spikelets (Hortorium 1976).

Species: A. gerardi Vitman (big bluestem)

Flowers between August and early October. Commonly occurring along stream banks and roadsides and in moist meadows (Rhoads and Block 2000). Usage: Andropogon sp. macrobotanical remains are reported from archaeological contexts in the Northeast (Crawford and Smith 2003). Ethnobotanical studies describe this grass as being used for building material, medicines (Gilmore 1919), and containers (Castetter and Opler 1936). Description of Starch: Assemblage primarily comprised single grains. Grains average 14.6 µm in size. Hila are positioned centrically. Initial and transverse fissures witnessed. Rounded to subrounded spheres occur in high frequencies. “Dimpled” surface texture (similar to the surface of a golf ball). This surface texture can be severe, covering the entire grain, or subtle, only vaguely pronounced. Grains exhibiting this morphology occur in low frequencies throughout the assemblage. Birefringence well defined, arms tend to cross straight through the centric hilum.

Figure 6: Andropogon gerardi.

Distribution: http://plants.usda.gov/java/profile?symbol=ANGE.

Genus: Schizachyrium Fewer than 100 spp. widely distributed around the world. These can be distinguished from Andropogon by their solitary racemes at the ends of the stems and their branches (Hortorium 1976). Species: S. scoparium (Michx.) Nash (little bluestem) [syn: Andropogon scoparius]

Flowers in early August to early October (Rhoads and Block 2000). Usage: Native peoples are described as using the culms of S. scoparium for a wide range of utilitarian purposes (Carlson and Jones 1940). Description of Starch: Assemblage primarily comprised single, subrounded spherical grains. Grains range in size from 5–21.25 µm, with an average of 13.68 × 11.85 µm, and a mean size of 12.76 µm. Fissuring is uncommon but tends to be of the longitudinal to initial type when present. Severe cracking also witnessed. Surface texture varies from smooth to intensive cracking, pitting, and dimpling. Faint dark lines can often be detected radiating from the centric hila. Starch is not well represented within S. scoparium. Starch appears to be easily damaged by processing, often resulting in the distortion or elimination of birefringent properties.

Figure 7: Schizachyrium scoparium.

Distribution: http://plants.usda.gov/java/profile?symbol=SCSC. Genus: Sorghastrum About 15 spp. of perennial grasses in America and Africa. Stems erect, leaf blades narrow and flat; panicles also tend to be narrow (Hortorium 1976).

Species: S. nutans (L.) Nash (Indian-grass) [syn: Sorghastrum avenaceum (Michx.) Nash.]

Flowers in August to September. Perennial, moist or dry fields, barrens, and roadsides—upland species (Rhoads and Block 2000). This genus has C4 photosynthetic pathway (Edwards and Walker 1983). Usage: No known usage. Description of Starch: Assemblage primarily comprised spherical to dome-shaped single grains. These range in size from 4–18 µm, with an average size of 10.84 × 9.81 µm and a mean of 10.32 µm. Grains tend to be subrounded. Irregularity can be severe and is most likely caused by packing. Fissuring is uncommon; however, when encountered fissures were initial to transverse in orientation and extremely small in size. Hila are centric to semi-eccentric. Starch only produced in small amounts. The largest grains seem to be highly susceptible to damage, as seen in their weak birefringent property.

Distribution: http://plants.usda.gov/java/profile?symbol=SONU2.

Genus: Zea Species: Z. mays ssp. mays type Parker’s Flint (maize) Usage: See Chapter 2. Description of Starch: Assemblage primarily comprised single spheres, polygonal and irregular subangular forms, with the latter occurring with the highest frequency. Grains range in size from 5–20 µm, with an average size of 14.6 × 13.4 µm and a mean size of 14 µm. Surfaces and edges of irregular forms vary

widely and appear highly ragged. Stellate, tripartite or Y-shaped, initial, and longitudinal fissures also common—more so than on any other taxon surveyed. Hila are centric and often open. Birefringence is well defined and arms appear straight to wrinkled—a reflection of the uneven surface topography. Lamellae not witnessed. Starch is well represented in kernels and appears to be resilient to moderate levels of processing.

Figure 9: Zea mays Parker’s Flint.

Species: Z. mays ssp. mays type Winnebago Flint (maize)

Description of Starch: Assemblage primarily comprised single, spherical and subangular highly irregular forms. These tend to range in size from 5–23 µm, with an average size of 15.98 × 15.2 µm and a mean size of 15.58 µm. Surface textures vary from smooth (mainly present in spheres) to highly irregular or ragged surfaces and edges. Fissures common; these appear as stellate, transverse, or tripartite Y patterns. Birefringence is well defined and arms vary from straight to wrinkled. Hila are arranged centrically and tend to be open.

Figure 10: Zea mays Winnebago Flint.

Species: Z. mays ssp. mays type Indian Graves Flint (maize)

Description of Starch: Assemblage primarily comprised single (simple), spherical, subangular, and often highly irregular forms. Grain size ranges from 4–19 µm, with an average size of 13 × 12.3 µm and a mean size of 12.68 µm. Hila tend to be open, tripartite Y-shaped fissures present in assemblage. Spherical forms appear with greatest frequency. Birefringence well defined, arms straight in spheres and bent in angular forms. Dark radial lines extending outward from the hilum are often visible in spherical forms.

Figure 11: Zea mays Indian Graves Flint.

Tribe: Paniceae Genus: Digitaria

Over 100 spp. of annual or perennial widely dispersed taxa. These tend to be thought of as weeds. Inflorescence appears to digitate along slender racemes. Spikelets lanceolate or elliptic and often rounded on one side and nearly flat on the other. These tend to be paired or in threes (Hortorium 1976).

Species: D. serotina (Walter) Michx. (dwarf crabgrass)

Flowers between August and October. Native east of Pennsylvania (Rhoads and Block 2000). Usage: Seeds of D. cognata (fall witchgrass) were used by the Hopi as a food resource. Vestal (1940) notes that the seeds of D. serotina were ground into meal. Crawford and Smith (2003) report the recovery of Digitaria sp. seeds from archaeological sites in the Northeast. Description of Starch: Assemblage comprised single (simple and clusters) subrounded grains. The starch of this assemblage ranges in size from 2–5 µm. The small size of these grains prohibits a detailed examination. Subtle flattening of edges is present. Birefringence well defined and arms cross through the centric hilum, which appears to be generally closed. No fissures witnessed. Starch only produced in small amounts.

Distribution:http://plants.usda.gov/java/nameSearch?keywordquery=Digitaria+serotina&mode=sciname&submit.x=12&submit.y=6. Genus: Echinochloa About 20 spp. of annual or perennial grasses in warm countries. The flower sheaths tend to roll in on themselves, leaf blades linear and flat; panicles tend to be compact, of short, densely flowered racemes along a main axis. Spikelets are rounded on one

side and flat on the other, solitary or irregularly clustered on one side of the panicle branches (Hortorium 1976). Species: E. muricata (P. Beasuv.) Fernald var. muricata (rough barnyard grass) [syn: E. pungens (Poir.) Rydb.]

Flowers in August and September. Moist ground and alluvial landscapes (Rhoads and Block 2000). Usage: Crawford and Smith (2003) report the recovery of a different species of Echinochloa, E. crus-galli, from archaeological sites in the Northeast. According to Rhoads and Block (2003) as well as the USDA Plants Database, this species of Echinchloa is not native to North America. Ethnographic and ethnobotanical studies also describe Native peoples as intensively utilizing the seeds of E. crus-galli. The Yuma processed the seeds for consumption by pounding, winnowing, parching, and then grinding them into meal (Castetter and Bell 1951:187). The Tubatulabal used these seeds extensively as food, as did the Paiute and Cocopa (Gifford 1933:267; Steward 1933:243; Voegelin 1938:15). Description of Starch: Assemblage primarily comprised single (simple and clusters) polygonal grains. Grains range in size from 4–11.5 µm and have an average size of 8.1 × 7.6 µm, with a mean size of 7.82 µm. The majority exhibit sharp edges. Grain surfaces grade from smooth to ragged. Spheres are also present in the assemblage but occur in the minority. Surfaces of spheres are smooth. Birefringence is well defined; arms cross through a centric hilum that varies from open to closed. No fissuring witnessed.

Distribution: http://plants.usda.gov/java/profile?symbol=ECMU2.

Genus: Paspalum About 400 spp. distributed throughout the world. These tend to be both annuals and perennials. Spikelets are compressed but slightly convex on the sides, usually obtuse, early sessile, solitary or paired, in two rows on one side of the rachis (Hortorium 1976).

Species: P. distichum L. (knotgrass)

Flowers between June and October. Prefers moist, wet places (Stubbendieck et al. 2003). Usage: Crawford and Smith (2003) report the recovery of P. distichum from archaeological sites in the Northeast. Description of Starch: Assemblage primarily comprised single (simple and clusters) polygonal and spherical grains. Polygonal forms tend to be angular, often with sharp edges, while spheres vary from subrounded to subangular. Size ranges from 2–7.75 µm, with an average size of 6.53 × 5.82 µm (mean length of 6.18 µm). Surfaces tend to vary from smooth to slightly undulating. Birefringence well defined—straight arms cross through a centric hilum that generally appears closed. No fissures witnessed.

Distribution: http://plants.usda.gov/java/profile?symbol=PADI6.

Genus: Setaria About 125 spp. of annual or perennial grasses in warm countries. Panicles are narrow, terminal, dense, and spikelike. They also can be somewhat loose and open, awnless with a broad first glume that is usually less than half the length of the spikelet. Three to five nerves generally present (Hortorium 1976).

Species: S. leucopila (Scribn. & Merr) K. Schum. (streambed bristlegrass)

Flowers between May and September. S. leucopila has the ability to produce more than one seed crop if adequate moisture is available (Stubbendieck et al. 2003). Usage: Austin (2006) puts forth that Setaria sp. seeds were a dominant cereal in the Americas for at least 1,500 years. Description of Starch: Assemblage primarily comprised single (simple) spherical to angular polygons. Grains range in size from 2–12.5 µm, with an average size of 8.47 × 8.56 µm. Flattening is attributed to packing. Surfaces tend to be smooth; however, a small percentage of the assemblage exhibits ragged surfaces and initial fissures radiating from the centric hilum. These ragged grains tend to be spheres. These traits are characteristic of Setaria and are of taxonomic value. Birefringence is well defined and arms of the cross tend to be straight.

Figure 15: Setaria leucopila.

Distribution: http://plants.usda.gov/java/profile?symbol=SELE6.

Species: S. macrostachya Kunth (large spike bristlegrass) Open, dry areas and woods around the southwest United

States (Hitchcock 1971). Usage: Seeds from Setaria sp. were recovered from the intestinal tracts of two desiccated bodies found in the Southwest. The first was radiocarbon dated at ca. A.D. 850 (Turpin et al. 1986). The second dated to A.D. 1080–1220 and the seeds showed signs of processing using a mortar and pestle (Austin 2006:151). Though a more specific taxonomic identification was not provided, there

are several naturally occurring Setaria species in this area, including S. macrostachya (Correll and Johnston 1970). Description of Starch: Assemblage primarily comprised single (simple) spherical to angular polygonal forms. Grains range in size from 2–10.75 µm and have an average size of 7.75 × 7.46 µm. Most grains have smooth surfaces, although some exhibit ragged surfaces indicative of this genus. Tripartite or Y-shaped to initial fissures also present in the assemblage.

Distribution: http://plants.usda.gov/java/profile?symbol=SEMA5.

Species: S. magna Griseb (giant bristlegrass) Prefers marshes and poorly drained areas (Hitchcock 1971).

Usage: Only two species of Setaria are known to be native to the Middle Atlantic and Northeast regions–S. magna and S. parviflora (Fernald 1950; Hitchcock and Chase 1950). Crawford and Smith (2003) report small quantities of carbonized Setaria recovered from the Seed-Barker site located on the northwest side of Lake Ontario. Hart and Asch Sidell (1996) also recovered Setaria seeds from the Memorial Park site located on the West Branch of the Susquehanna River dated to A.D. 800–1350. Description of Starch: Assemblage primarily comprised single (simple) spheres and angular forms. Grains range in size from 2–7.5 µm, with an average size of 6.33 × 5.95 µm and a mean size of 6.14 µm. Ragged and slightly dimpled surface textures are present. Fissures are uncommon, but when present they are only slight/initial. This surface texture, in conjunction with size,

is a recognizable trait of Setaria. A small percentage of the assemblage exhibits black lines radiating away from the hilum. Birefringence is well defined. Straight “arms” cross through the centric hilum.

Distribution: http://plants.usda.gov/java/profile?symbol=SEMA6.

Species: S. parviflora (Poir.) Kerguelen (marsh bristlegrass)

Usage: Only two known species of Setaria are present in the Middle Atlantic and Northeast regions—S. parviflora and S. magna (Fernald 1950; Hitchcock and Chase 1950). Crawford and Smith (2003) report the recovery of small quantities of Setaria from the Seed-Barker site located northwest of Lake Ontario. At Memorial Park, located on the West Branch of the Susquehanna River in Pennsylvania, Setaria was also recovered (Hart and Asch Sidell 1996). Austin (2006) points out that S. parviflora is present in all areas where Setaria is known archaeologically. Description of Starch: Assemblage primarily comprised single (simple and clusters) spheres (globose) and subangular forms. Grains range in size from 2–10 µm and average 7.67 × 7.13 µm. Packing results in angularity. Ragged surfaces (mildly dimpled) and fissures (initial) present in small frequencies; these traits combined with their size are specific to Setaria. Birefringence well defined; straight arms cross through centric hilum.

Differentiating Within Poaceae

Panicoideae: Maize and the Millets In spite of the presence of similar features among the

Panicoideae based on shared evolutionary history, bold morphological distinctions regularly occur throughout this subfamily that allow for identifications to be made on high taxonomic levels (Figure 48). These distinctions include grain size and a combination of morphological attributes, including fissure type and expression, overall grain shape, and the presence of unique surface features.

Two tribes of Panicoideae were studied here, Paniceae and Andropogoneae. Starch grain size varies consistently between these two groups, with the Paniceae generally producing smaller grains than those of Andropogoneae (Figure 47) (Holst et al. 2007). The Paniceae tribe tends to produce starch grains consistently averaging around ~8 µm, while those of Andropogoneae tend to be significantly larger, ~13 µm.1

While most genera within Paniceae overlap in size, several morphological traits are taxonomically valuable for identifying and distinguishing between two economic genera in this tribe, Panicum and Setaria. Several species of Setaria, including S. magna (giant bristlegrass), produce a spherical to oval-shaped grain that exhibits a rather wavy and ragged surface texture. Ragged to dimpled morphotypes are also present in the Andropogoneae tribe (discussed further below); however, the surface texture of Setaria can be distinguished by its application, pronunciation, and overall grain size. Panicum virgatum (switchgrass) tends to produce grains that exhibit severe angularity of the margins, often appearing similar to sharp, irregular edges. Fissures also tend to be present in this assemblage; these are usually of the tripartite Y-shaped or stellate type. Fissures in general are rare in all other Paniceae taxa studied. These attributes are therefore specific to P. virgatum and are of taxonomic value.

In Northern Flint maize there exist two main types of starch produced within each kernel (see Dombrink-Kurtzman and Knutson 1997; Piperno and Holst 1998; Zarrillo and Kooyman 2006:491). The first is a soft or floury endosperm variety, which tends to range in size from 4–24 µm and has an irregular rounded to spherical form with smooth surfaces, often a distinct double border and a lack of lamellae. This type is consistent with other soft endosperm maize studied in Central and South America as well as in the Canadian Great Plains (Pearsall et al. 2004:430–432; Perry 2001:136; Piperno et al. 2000:897; Zarrillo and Kooyman 2006:491). In two of the flint varieties studied, Parker’s Flint and Winnebago Flint, the soft endosperm starch occurs in the minority (Brown and Anderson 1947). The second type, the hard or flint endosperm variety, is diagnostic of this species (Holst et al. 2007; Piperno and Holst 1998:766). Flint endosperm grains tend to exhibit the following characteristics: (1) large grain size (often reaching ~20 µm in size), (2) ragged, subangular, irregular surface topography that appears three dimensionally across the grain thus resulting in a highly irregular form2; grains occasionally have smooth pointed to almost rounded jagged edges and (3) a propensity toward fissuring, with Y-shaped and stellate types occurring most frequently (these are often deeply incised and expand outward from the hilum); (4) lamellae are not visible; however, (5) a distinct and continuous double border often is; (6) the hilum is positioned centrically to semi-eccentrically (Cortella and Pochettino 1994:175–176; Pearsall et al. 2004:430–432; Perry 2001:136; Piperno and Holst 1998:775; Piperno et al. 2000:897; Reichert 1913:346–348; Zarrillo and Kooyman 2006:490–491). These attributes are diagnostic of Zea mays and are integral for distinguishing this species from all other grasses native to the prehistoric Eastern Woodlands.

Several Poaceae genera studied produce starch grains of comparable size to Zea. Starch from Tridens flavus (purpletop tridens) can rival Zea mays in size. In spite of this potential overlap, starch from T. flavus differs in very distinctive ways. First, Tridens tends to have highly angular edges that almost appear sharp, with grain shapes that mimic highly ordered polygonal forms. Second, Tridens grains studied here also failed to exhibit evidence of fissuring and the grain surfaces tended to be smooth. Chasmanthium latifolium (sea-oats) of Centotheceae also overlaps in size with Zea. This species exhibits a wavy, sometimes ragged surface topography especially around the margins; however, Chasmanthium lacks the distinctive well-incised Y-shaped to stellate fissures common in Zea mays. Both Tridens flavus and Chasmanthium latifolium starch are highly susceptible to processing damaged, especially within the largest

grain sizes. This damage often causes the central portion of the grain to collapse, thereby obscuring birefringence and leaving a feature much like a crater encompassing the majority of the grain.

Maize starch also overlaps in size with Andropogon gerardi (big bluestem) and Schizachyrium scoparium (little bluestem). Both A. gerardi and S. scoparium produce predominantly rounded forms, often with pressure-flattened edges. Initial transverse and radial fissures are sometimes noted in the latter. Neither of these taxa exhibits diagnostic morphological features common in Zea. Alternatively, both Andropogon (bluestem) and Schizachyrium (little bluestem), often produce starch that exhibits a highly ordered dimpled surface texture (similar to the surface of a golf ball), a trait not present in Zea mays starch populations.

Pooideae All Pooideae taxa studied, with the exception of the tribes

Bromeae and Triticeae (discussed further below), produce starch assemblages consisting of compound grains made up of ~12–3,000 individual polygonal to spherical granules.3 The number of granules present has a negative correlation to their size (Reichert 1913:273). For instance, individual granules comprising grains of Agrostis hyemalis (winter bentgrass) tend be ~2 µm. Each individual bentgrass grain is therefore made up of thousands of tiny granules. Alternatively, starch grains of Avena fatua (wild oat) tend to be larger (~7 µm) and as a result individual grains consist of far fewer granules (between 20 and several hundred grains). All Pooideae granules studied appear angular to polygonal in form, with flattened surfaces due to packing, or as oval to spherical. The amount of angularity present also tends to vary among taxa. For instance, granules studied within Phalaris (canarygrass) tend to grade from subangular to angular polygonal forms, often with sharp edges, while Koeleria (Junegrass) granules tend to be rounded to irregularly subround forms.

Theoretically, each granule composing a grain should react when viewed under polarized light (Barton and Fullager 2006:50; Loy 1994; Perry 2001; Piperno and Holst 1998). Each of the Pooideae grasses studied here exhibits at least subtle traces of an extinction cross when viewed under cross-polarized light (as both articulated grains and disarticulated granules). In other non-Poaceae taxa, the small granule size tends to obscure birefringence, resulting in starch that glows in polarized light but fails to produce an extinction cross. This birefringent property may aid in distinguishing between compound grains produced in Poaceae (particularly members of the Pooideae tribe)

and in other nonrelated taxa such as Chenopodium berlandieri (chenopod) and Nuphar lutea (yellow pond-lily).

Also present within Pooideae are two tribes that produce single lenticular-shaped starch grains. The first, Bromeae, is a small tribe composed of only one genus, Bromus (USDA NRCS 2008). Only one of the six species included in this collection, Bromus marginatus, can be found in the Middle Atlantic region (USDA NRCS 2008). Starch from this species generally averages less than 10 µm in size.

The tribe Triticeae also produces lenticular-shaped starch grains. Triticeae consists of the Old World domesticates, wheat and barley, as well as the New World quasi-domesticate Hordeum pusillum (little barley) and a range of potentially economic wild species such as Elymus canadensis (wildrye). Plants of Triticeae have a propensity toward hybridization (Renvoize and Clayton 1992). In spite of this, starch from Old World domesticates such as Triticum aestivum (wheat) and Hordeum vulgare (barley) not only can be differentiated from each other (Henry and Piperno 2008; Piperno et al. 2004) but also can be distinguished from New World taxa. Hordeum vulgare tends to exhibit concentric lamellae and initial fissures in plan view (Henry and Piperno 2008). These traits are also present in other Old World Hordeum taxa (Henry and Piperno 2008; Piperno et al. 2004; Reichert 1913:372). Lamellae were not witnessed in starch produced by either of the New World taxa, Hordeum pusillum (little barley) or Hordeum jubatum (foxtail barley). In fact, grain surfaces in plan view tend to be smooth and generally featureless except for an occasional initial longitudinal fissure. H. pusillum also tends to exhibit a hilum that appears enlarged, much like a spherical void in the botanical center of the grain. This void was not noted in any of the Old World taxa nor within the six species of native perennial Elymus spp. (wildrye). This characteristic may be diagnostic of this species; however, further comparative work is needed to substantiate this determination. In profile, Hordeum pusillum grains also have an elongated rodlike shape (with rounded ends). A faint longitudinal fissure is also present in this view, but it rarely extends the length of the grain.

Figure 49: One standard deviation above and below the mean length of Triticeae grains.

Triticum aestivum (wheat) starch also failed to exhibit visible lamellae in plan view (Henry and Piperno 2008; Piperno et al. 2004). Surface topography in these grains often tends to undulate severely. “Crater-like” depressions are often visible, sometimes covering a large portion of the grain surface (Henry and Piperno 2008; Piperno et al. 2004). Slight, initial longitudinal fissures are also occasionally visible in plan view. 1 The majority of the taxa studied from Paniceae fall within this 7–10 µm range. 2 In some varieties of maize, researchers also note the presence of hemispherical and “vase” shaped grains (Pearsall et al. 2004:430; Zarrillo and Kooyman 2006:490). 3 These all fall within Reichert’s (1913) “Type 16 Grains Compound, Many Components” group.

Family: Polygonaceae Genus: Polygonum Species: P. amphibium L. (water knotweed) Rhoads and Block (2000:547) describe this species as a robust perennial with oval to lanceolate leaves, stout rhizomes, trailing on water, flowers pink to red on a terminal spike. Frequent on shores of lakes and in ditches. Usage: According to ethnobotanical studies, rhizomes of Polygonum amphibium were used for a wide range of medicinal purposes (Leighton 1985; Turner et al. 1980). Description of Starch: Assemblage (rhizome) primarily comprised single (simple) ovoid to elliptical forms with acuminate distal ends and irregular subangular grains. Grains range in size from 5–20 µm, with an average size of 14 × 9 µm. Hila arranged eccentrically and are often open. Fissures infrequent and when present are of the stellate type. No lamellae noticed and birefringence is well defined.

Figure: Polygonum amphibium (rhizome).

Distribution:http://plants.usda.gov/java/profile?symbol=POAM8. Species: P. hydropiper L. (marshpepper knotweed) Rhoads and Block (2000:550) describe this annual as ascending from a taproot, having reddish branches, lanceolate leaves, achenes with both three sides and lens shapes; prefers wet meadows, swamps, and stream margins. Native to Europe.

Description of Starch: Assemblage (seed) primarily comprised single (simple and clusters) spherical (globose) forms. Grains range in size from 2–5 µm. Hila are positioned centrically. Birefringence is well defined. Subtle flattening common, as is a continuous bold/thick border (almost double border). No lamellae or fissures witnessed.

Figure: Polygonum hydropiper.

Distribution: http://plants.usda.gov/java/profile?symbol=POHY.

Species: P. pensylvanicum L. (Pennsylvania smartweed) Rhoads and Block (2000:550–551) describe this plant as erect and ascending from a stout taproot, leaves broad lanceolate, spikes cylindric and erect, fruiting calyx pink, achenes lens shaped and somewhat flattened or depressed on each side. Prefers moist ditches, meadows, fields, and waste places. Usage: Polygonum seeds often occur in the macrobotanical record. There is strong evidence supporting the hypothesis that Polygonum erectum was cultivated in the Midwest (Asch and Asch 1985). Description of Starch: Assemblage primarily comprised single (simple and clusters) spherical (globose) grains. Grains range in size from 2–5 µm; often subtle flattening present due to packing. Hila arranged centrically. No lamellae or fissures witnessed. Continuous bold/thick double border is often present. Birefringence well defined. A straight cross is formed through the centric hilum.

Figure: Polygonum pensylvanicum.

Distribution: http://plants.usda.gov/java/profile?symbol=POPE2.

Summary: Polygonum Starch is produced in large quantities within the seeds and rhizomes. Polygonaceae produces subrounded starch with smooth to slightly flattened surfaces, continuous thickened borders, and lacking fissures. Starch from Polygonum amphibium rhizomes is characteristic of this species. These elongate grains have an eccentric hilum, are <17 µm in length, lack fissures, and are sometimes bent.

Family: Smilacaceae Genus: Smilax Rhoads and Block (2000:997) describe these plants (greenbrier) as a rhizomatous climbing vine often with prickles, ovate to ovate-lanceolate leaves, bluish fruit; prefers moist to dry woods, thickets, and old fields. Usage: Ethnobotanical accounts describe Native peoples as using the rhizomes of this plant for dietary purposes (Hamel and Chiltoskey 1975; Speck 1941). Description of Starch: Assemblage (rhizome) primarily comprised single (simple and clusters) dome/hemispherical-shaped grains. These range in size from 5—20 µm, with an average size of 14 × 14 µm; usually two to three flattened surfaces occur on the distal surface. Hila vary from centric to semi-eccentric, with an initial to slight V-shaped fissure rarely occurring. Concentric lamellae present. Birefringence bold and well defined and arms appear straight.

Figure: Smilax sp. (rhizome).

Distribution: http://plants.usda.gov/java/profile?symbol=SMILA2.

Summary: Smilax sp. Starch is produced in moderate levels within the rhizomes of this taxon, at least on a seasonal basis. These grains are taxonomically valuable, particularly the large symmetrical dome forms that are of nearly equal length and width and exhibit concentric lamellae and a small facet positioned bilaterally.

Family: Typhaceae Genus: Typha Species: T. latifolia L. (common cattail) Rhoads and Block (2000:1001) describe this aquatic plant as reaching 1—3 m in height, with flat lanceolate leaves 10—23 mm wide. Common in swamps, in marshes, and on wet shores. Usage: Cattail served many purposes in Native economies. The starch-rich rhizomes were used for treating a large number of different ailments (Black 1980; Herrick 1977; Tantaquidgeon 1972). Rhizomes were also used for dietary purposes (Castetter 1935; Heller 1953; Leighton 1985). Description of Starch: Assemblage (rhizome) comprised single (clusters) bells and domes. These grains range in size from 2–20 µm, with an average size of 9 × 8 µm. Facets vary from one to three in number. Hila positioned centrically to semi-eccentrically. Lamellae and fissures uncommon. Birefringence well defined and arms appear straight.

Figure: Typha latifolia (rhizome).

Distribution: http://plants.usda.gov/java/profile?symbol=TYLA.

Summary: Typha latifolia Starch is produced in large amounts within the rhizomes of this taxon. Many of these forms occur across a

wide range of unrelated taxa, although some are of taxonomic value. These grains tend to have bell shapes that appear rounded at the proximal end and taper, often drastically, to the distal surface. Works Cited: Black, M. J. 1980 Algonquin Ethnobotany: An Interpretation of
