FNA: Dalea multiflora vs. Dalea urceolata

	Dalea multiflora	Dalea urceolata
	roundhead prairie clover	pineforest prairie clover
Stems	3–8 dm, glandular-punctate.
Inflorescences	spikes, densely flowered, nearly globose, inconspicuously involucrate (lowest bracts not subtending flowers), 7–9 mm diam.; axis not visible, 0.4–1(–1.2) cm; bracts early deciduous or proximals persistent, interfloral ones held in place by crowded flowers, 2–2.4 mm.
Peduncles	(0–)0.5–3(–7) cm.
Stamens	5, (5–)5.2–7.6 mm, filaments distinct to 2.5–4.5 mm, anthers 0.7–1.2 mm.
Corollas	white; not conventionally papilionaceous; banner (4–)4.2–5.7 mm, blade deltate-obovate, 2.3–3.4 × 2.4–3.7(–4.2) mm; epistemonous petals attached at separation of filaments, blades 2.3–3.5 × 1.5–2.1 mm.
Calyces	subsymmetric, (2.9–)3–4.2(–4.4) mm, glabrous, lobes ciliolate; tube 1.6–2.6 mm, not deeply recessed opposite banner, with 1(–3) small blister glands between ribs, lobes lanceolate to triangular, ± unequal, abaxial pair longest.
Legumes	2.5–3 mm, glabrate, with ± prominent elongated glands on sides.
Seeds	1.6–2 mm.
Perennial	herbs, erect to spreading, glabrous.
Principal	leaves 2–3 cm; leaflets (7 or)9 or 11(or 13), blades oblong to elliptic-oblanceolate, or linear-oblong, 7–13 mm.
Dalea		urceolata is remarkable for its reduced corolla with two epistemonous petals and is rare throughout most of its range.

	Dalea multiflora	Dalea urceolata
Phenology	Flowering late spring–early fall.
Habitat	Prairies, rocky hills.
Elevation	0–700 m. (0–2300 ft.)
Distribution	CO; KS; MO; NE; OK; TX [WildflowerSearch map] [BONAP county map]	sw United States; Mexico [BONAP county map]
Discussion	Dalea multiflora shows considerable geographic variation in stature. Its floral structure is similar to that of D. candida var. candida, and individuals intermediate between the two species occur (R. C. Barneby 1977c). In Texas, D. multiflora is known from the eastern two-thirds of the state. (Discussion copyrighted by Flora of North America; reprinted with permission.)	Varieties 3 (1 in the flora). Variety tripetala (Paul G. Wilson) Barneby occurs in south-central Mexico (Michoacán to Morelos) and has fewer stamens (5–7) than var. urceolata (7–10). Variety lucida (Rose ex Rydberg) Barneby occurs in Durango and lacks the epistemonous petals; the banner is the only petal.
