oakwoods dalea, oakwoods prairie clover

pussyfoot
Stems

to 5.5 dm, sparsely dotted with small, raised glands.
Inflorescences

axis not visible, 3.5–11 cm;

bracts early deciduous, interfloral ones often held in place by crowded flowers, 5.5–11 mm.
Peduncles

Barneby

(1977c) used a hierarchical classification for this large, mainly Mexican species.

Variety

sessilis is one of four varieties in subsp. versicolor;

three other varieties are recognized in subsp. argyrostachys (Hooker & Arnott) Barneby.

The

complex variation in this group is further complicated by seasonal dimorphism.

In

fall-blooming plants, relatively elongated spikes terminate long shoots; in spring-blooming plants, shorter and more numerous spikes are borne on short shoots from the axils of fallen leaves.

Perennial

herbs, short-lived, erect, ± lanate-pilose.
Principal

leaves (2–)2.5–5 cm;

leaflets 7–11, blades obovate, (8–)10–16 mm, surfaces eglandular.

Dalea versicolor

Dalea obovata
Phenology Flowering spring (fall–early winter).
Habitat Sandy, open ground on and near Gulf Coastal Plain.
Elevation 0–400 m. (0–1300 ft.)
