Fruit Type: Legume
Size Notes: "Stems mostly 3-20 cm long." (bibref: 1812).
Leaf: "Leaf-spurs 0.4-1.5 mm long; stipules thinly herbaceous becoming stramineous, narrowly triangular-subulate to lance-acuminate, 0.6-1.8 (2.4) mm long, pilosulous and often gland-pustulate dorsally; post-petiolular glands prominent, livid or orange, often scattered on the rachis (not exactly behind the petiolule); foliage gray-silky, the leaflets pubescent above and beneath; leaves 0.8-2.5 (3.2) cm long, the cuneate-obcordate leaflets strongly gland-undulate." (bibref: 1812). "Leaves at least shortly petioled, 0.8-4.5 cm long, with narrowly margined rachis and (3) 4-7 pairs of obovate to obovate-oblong or cuneate-obcordate, obtuse, truncate-emarginate, or widely and openly retuse, flat or loosely folded leaflets 2.5-8 mm long, the margins either plane or strongly undulate-crenulate, the lowest and uppermost leaflets usually smaller than the rest, the leaf-outline therefore more or less oval-elliptic." (bibref: 1812).
Flower: "Peduncles 0.3-3.5 cm long; calyx mostly 6.6-8 mm long, the tube 2.4-3.1 mm, the teeth (3.4) 3.8-5.2 (5.7) mm long; petals usually whitish variegated with dull crumson, rarely yellowish/" (bibref: 1812). "Peduncles slender, incurved-ascending, 3-40 mm long, bringing the raceme to vertical or almost so; racemes moderately dense, ovoid becoming oblong, the flowers ascending in bud, early spreading, at least the lowest nodding in age, at full anthesis (pressed) 1.3-1.6 (1.8) cm diam, the pilosulous axis 1-6 cm long; bracts early deciduous, lance-acuminate or -caudate, (3) 3.5-6 mm long, thinly herbaceous becoming papery, greenish or commonly livid-purpurascent, dorsally pilosulous and glandular; pedicels 0.3-0.6 (0.7) mm long, subtended by and charged near apex with a pair of prickle-shaped or mammiform, livid or nigrescent glands 0.2-0.7 mm long; calyx 4.7-8 (8.8) mm long, densely pilose with fine spreading spiral hairs up to (1.2) 1.5-2.2 (2.6) mm long, the tube 2.1-3.1 mm long, the ribs firm but slender, the hyaline intervals charged vrith 1 (sometimes irregular) row of 5-7 (9) small, often orange, sometimes transparent glands, the teeth aristiform from a deltate or broadly triangular base, 2.5-5.7 mm long, in age plumose; petals usually bicolored, the eye of the whitish (yellowish) banner green turning, like the keel-blades, dull crimson, the rest varying from whitish to pale straw-yellow and variably pinkish-tipped, none gland-tipped but all charged near base with a few small glands, the wings perched below middle of androecium and disjointing from it, the keel-claws continuous from hypanthium but adnate nearly to middle of androecial tube, marcescent; banner 4-5.6 mm long, the claw 1.4-2.6 mm, the deltate, acute or subacute, rarely minutely emarginate, basally cordate sagittate blade (2.8) 3-3.7 mm long, 2.3-3.4 mm wide; wings (measured from joint) 3.3-4.2 mm long, the claw 0.7-1.2 (1.5) mm, the obliquely ovate blade broadest near middle, narrowed but obtuse distally, 2.4-3.3 mm long, 1.3-1.8 mm wide; keel (measured from hypanthium rim) 4.5-7.1 (7.5) mm long, the claws (half adnate) 2-4.2 mm long, the obliquely obovate, puckered blades 2.4-3.2 mm long, 1.8-2.2 (3) mm wide; androecium 10-merous, 5-6.7 (7.2) mm long, the longer filaments free for 1.3-2.4 mm, the connective minutely gland-tipped or glandless, the anthers 0.5-0.7 (1) mm long." (bibref: 1812).
Fruit: "Pod 2.3-3 mm long, in profile obliquely obovate, the style-base lateral just below apex, the valves hyaline in lower 1/2-2/3, thence thinly papery, pilose, eglandular, the prow more or less thickened, cordlike, glabrate; seed brown, lustrous, 1.7-2.4 mm long." (bibref: 1812).

Bloom Information

Bloom Notes: "Petals usually bicolored, the eye of the whitish (yellowish) banner green turning, like the keel-blades, dull crimson, the rest varying from whitish to pale straw-yellow and variably pinkish-tipped." (bibref: 1812).

Distribution

USA: AZ , NM , TX
Native Distribution: "Local but somerimes abundant, scattered over the northern Chihuahuan Desert from near 27° 30' N, northwestern Coahuila and eastern Chihuahua northward from middle Conchos Valley, and across Rio Grande (Bravo) into southern and western Trans-Pecos Texas (Brewster, Presidio, Hudspeth counties, north to the Glass Mountains); unknown as yet from northern Chihuahua but reappearing near the Continental Divide in southwestern New Mexico (Grant and Hidalgo counties), thence west to the edge of the Gila Basin in southeastern Arizona (Cochise, eastern Pima, Santa Cruz counties) and south to the headwaters of Rios Magdalena and Sonora in northeastern Sonora; disjunct (and atypical; cf. discussion infra) on low hills along the Rio Grande, at ± 180 m, in Webb County, Texas." (bibref: 1812).
Native Habitat: "Stony hills, knolls, and washes, in arid grassland transitional to desert, on a variety of sedimentary and volcanic substrates, rarely on gypsum, mostly 700-1750 m (2100-5300 ft)." (bibref: 1812).
