|
Stems | (1.5–)2.5–10(–15) dm, ± sparsely glandular-verruculose distally. |
|
Inflorescences | spikes, relatively densely flowered, not involucrate, 8–12(–15) mm diam.; axis usually not visible, (0.8–)1.5–7(–10) cm; bracts deciduous by anthesis, 2.5–7 mm. |
|
Peduncles | (1.5–)3–12(–15) cm. |
|
Stamens | 9 or 10, 5–6.8 mm, filaments distinct to 0.6–1 mm, anthers 0.2–0.4 mm. |
|
Corollas | white to purple or blue; not conventionally papilionaceous; banner (3.4–)4.4–6 mm, blade ovate to oblong-elliptic, (1.7–)2–3.7 × 1.2–2.4 mm; epistemonous petals attached near or distal to middle of stamen tube, blades (1.3–)1.6–2.4 × (0.4–)0.5–1 mm, laterals often slightly narrower than abaxials. |
|
Calyces | asymmetric, recessed opposite banner, 3–5.2 mm, sparsely to densely pilose or pilosulous; tube (1.7–)2–2.5(–2.8) mm, with (1 or)2 irregular rows of 2–6 small glands between ribs, sometimes merging into fewer, larger glands, lobes ovate-triangular to lanceolate-acuminate. |
|
Legumes | 1.4–3 mm, pilosulous distally and, sometimes, glandular-punctate. |
|
Seeds | 1.7–2.4 mm. |
|
Annual | herbs, erect, glabrous proximal to inflorescences. |
|
Principal | leaves 2–9.5 cm; leaflets (17–)21–35(–49), blades oblanceolate to obovate, (2–)3–12 mm. |

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. |

Discussion | Dalea leporina has the broadest range of any member of Dalea, from the interior of the United States and Mexico to Costa Rica, and is disjunct in the Andes Mountains of South America. It varies in some characters, most of which were regarded by R. C. Barneby (1977c) as trivial or not taxonomically useful. It has been found on occasion as a weed far east of its range, for example, in Massachusetts (D. E. Snyder 1950). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Varieties 7 (1 in the flora). Variety versicolor occurs in southern Mexico and Guatemala. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
