This research program was initiated in 1999 as part of an SDSU Agricultural Experiment Station funded program in the laboratory of Dr. R. Neil Reese. This project is designed to provide research and educational opportunities to students interested in conservation and utilization of native plant species, as well as encourage the use of native plants by small family farmers as alternative crops in South Dakota.

Onagraceae : Oenothera caespitosa
R. Neil Reese
Oenothera caespitosa is a perennial, acaulescent, mound forming herb from a branching caudex. Mature plants are typically 15-25 cm high and up to ~60 cm wide, with lateral roots giving rise to new plants. The leaf blades are oblanceolate to nearly linear, 3-21 cm long, 1-5 cm wide, with a winged petiole that is often as long as the blade. The margins vary greatly from almost entire to pinnately lobed to having irregular teeth that are rounded to sharp. The leaf blades, veins and margins can be variously covered with hairs or with hairs lacking. The flowers are solitary in the leaf axils, open near sunset and have a sweet scent. The floral tube is 3-8 cm long, slender and flared toward the end, often reddish in color. The sepals are 2.5-3.5 cm long lanceolate with pointed tips. The white petals are heart-shaped, 2.5-5 cm long, changing to pink after pollination. The 8 stamens are unequal in length and about 2/3 the length of the petals. The style is about as long as the petals and has a 4-lobed stigma. The fruit is a hard, lumpy, elongated capsule, 2-5 cm long with a constricted end. Gumbo lily blooms from May into August on dry, rocky prairies, hillsides and open woodlands in western and central South Dakota.

Onagraceae : Oenothera suffrutescens
R. Neil Reese
Oenothera suffrutescens is a perennial herb, usually with several branched stems growing 20-100 cm tall, from a branching caudex and spreading underground stems the generate new plants and form large colonies. The simple, alternate leaves are almost sessile, linear to narrowly elliptic, 5-60 mm long and 1-7 mm wide with a pointed tip, the margins entire to having a few small teeth. The inflorescence is a spike-like raceme, 5-60 cm long on a peduncle that is 1-6 cm long. The zygomorphic flowers appear sessile, each subtended by a bract. The floral tube is 4-12 mm long, with 4 sepals 5-10 mm long and 4 clawed (narrowed) petals 3-9 mm long and 2-4 mm wide, that are initially white, then changing to red-orange or reddish brown. There are 8 stamens, the anthers red or yellow and a central pistil with a style 10-20 mm long topped with a 4-lobed stigma. The fruit is a capsule 4-9 mm long constricted at the base. This species is highly variable in habit, flower color, size and pubescence, with plants ranging from smooth to densely hairy. Scarlet guara blooms from May into August in dry prairies, open wooded hillsides and stream valleys throughout South Dakota.

Papaveraceae : Argemone polyanthemos
R Neil Reese
Argemone polyanthemos is an annual to biennial plant with one to a few stems growing from a taproot. Plants vary greatly in size from 0.25 to 1.25 m in height with stems 7-20 mm in diameter. The stems are waxy with few to many yellowish prickles. The leaves are waxy with the upper surface smooth to bearing scattered prickles on the veins, with more prickles on the lower surface. The lower leaves are oblanceolate, deeply pinnately lobed, 7-25 cm long by 3-10 cm wide. The lobes are elliptical to obovate with undulating irregularly spiney-toothed margins and the petioles are winged. The leaves are reduced and become less lobed toward the top, but the margins are like those of the lower leaves. The flowers are 5-12 cm in diameter and are subtended by 2 bracts that are shorter than the sepals. The 3-6 yellowish sepals are 6-10 mm long. The 6-12 white petals are arranged in 2 rows, 2.5-5 cm long and nearly as wide. The center of the flower is dominated by numerous (~150) yellow stamens and the has 3-5 carpels. The fruit is a capsule 2.5-4 cm by 1-1.5 cm wide. The seeds are shiny, dark brown and round. Prickly poppy blooms from May until September. All parts of the plant have a yellow sap that stains the skin and clothing.

Papaveraceae : Sanguinaria canadensis
R. Neil Reese
Sanguinaria canadensis is a perennial herb with shallow, extensively branched rhizomes, 6-15 mm in diameter, that contain a red juice. The ends of the rhizome branchjes produce I leaf and 1 flower scape. At anthesis the leaf is usually shorted than the scape, but the petiole and blade rapidly expand and soon over tower the flower scape. The petiole reaches 10-35 cm in length, and the leaf blade becomes 6-20 cm long by 8-20 cm wide. The blade usually 3-7 lobed, almost circular in outline, green on top and waxy below, the margins entire to wavey. The flower forms at the end of a peduncle 5-12 cm long and has 2 rounded, membranous sepals, 2-12 mm long and 5-8 mm wide. The 8 (sometimes up to 16) white petals are oblanceolate to elliptic, 10-30 mm long and 5-12 mm wide, with 4 petals usually slightly larger than the others. The numerous stamens are up to 1 cm long with yellow anthers and the style is 2-lobed. The fruit is a spindle-shaped capsule, 3-5 cm long and 7-11 mm wide, containing ovoid, reddish brown seeds that have a prominent crest. Bloodroot blooms in late March into May on woodland slopes along the eastern edge of South Dakota.

Pinaceae : Pinus ponderosa
R. Neil Reese
Pinus ponderosa is a large evergreen tree with a pyramid-shaped crown that broadens with age and can reach 35 m in height. The trunk is straight, gray brown and furrowed when young, becoming scaley and gray mixed with orange brown with age, and the branches are gray black in color. The needle-like leaves are clustered toward the branch tips, usually 3 (2) per fascicle, 8-20 cm long, with small teeth along the margins. The fascicles emerge from a membranous, orange brown, deciduous sheath that is 1.5-2.5 cm long. Ponderosa pines are monoecious, the male cones are yellow orange, cylindrical, 1.5-3 cm long, in axillary clusters of 10-20 cones. The female cones are brown, woody, broadly ovoid, 6-12 cm long, 6-8 cm wide, and mature in the second year. Each cone scale has a thin prickle on the outer side. The seeds are in pairs underneath the scales, 6-7 mm long with a papery wing 3-4 times as long as the seed. The cones release pollen in May and June on low mountains and rocky hillsides in western and southcentral South Dakota.

Poaceae: Andropogon gerardii
R. Neil Reese
Andropogon gerardii is a perennial warm season bunch grass. Mature plants have a well-developed fibrous root system 2-3 m deep, sending out short rhizomes, forming large dense bunches. The stems grow 1-3 m tall and become purplish toward the base. which grows 5 dm to 20 dm in height. These culms are solid and grooved on one side. The leaves have prominent midribs but are not keeled, many at the base of the plant and a few coming from the culm. The ligule is a fringed membrane 0.4-2.5 mm long. The inflorescence is a raceme of 3 (2-6) narrow racemes alternately arranged along the top of the stem, often looking like a turkey foot. Each raceme contains many pairs of spikelets, each pair having a stalked spikelet with another stalkless spikelet at the base of the stalk. The stalkless spikelet usually has a fertile, perfect floret with an awn, and the stalked spikelet is sterile or has a staminate flower that is awnless. This species is commonly found in pastures, along roadsides, and in open prairies. Big bluestem has green rust-red flowers that bloom from July to October.
