Fruit Type: Legume
Size Notes: "Stems usually few, commonly 4-6, sometimes solitary, rarely up to 37, erect, ascending, or exceptionally diffuse or prostrate, (1) 1.5-8 dm." (bibref: 1813).
Leaf: "Stipules more or less dimorphic, those at the buried and lower emersed nodes papery-scarious, pallid or purplish-brown, often several- nerved, (1) 2-7 mm. long, amplexicaul and connate into a campanulate sheath, the median and upper ones nearly always smaller, herbaceous, ovate, triangular, or deltoid, commonly only semiamplexicaul, rarely briefly united at base; leaves 2-11 cm. long, the leaflets sometimes glabrous above, upper leaves, like those near base of stem, regularly even though remotely pinnate, the leaflets 3-4 pairs, linear, linear-filiform, or elliptic, commonly involute, exceptionally expanded and up to 3 mm. wide, 2-25 (33) mm. long." (bibref: 1813).
Flower: "Peduncles erect, incurved-ascending, or divaricate, (1) 3-14 cm. long, either longer or shorter than the leaf; racemes very loosely or remotely (1) 3-25-flowered, the flowers early spreading, at length declined and often irregularly secund, the axis (0.5) 2-18 (23) cm. long in fruit; bracts thinly herbaceous becoming papery, ovate or lanceolate, 0.5-2.3 mm. long, greenish, pallid, or purple-tinged; pedicels slender or subfiliform, at anthesis ascending at a wide angle or arched outward, 1-3.5 mm. long, in fruit straight and ascending, straight and divaricate, geniculate at base and refracted, or tortuous, 2-2.5 mm. long, tardily disjointing with the fruit; bracteoles 0, minute when present; calyx 4-6 mm. long, strigulose with black or white hairs, the symmetric or slightly oblique disc 0.6-1 (1.4) mm. deep, the campanulate tube 3.4-4.8 mm. long, (2.2) 2.5-5.3 mm. in diameter, rounded or obliquely turbinate at base, sometimes a trifle constricted at the mouth and then obscurely urceolate, the broadly subulate, triangular, or deltoid, mostly obtuse teeth 0.5-1.4 mm. long, the whole becoming papery, marcescent unruptured; petals ochroleucous, ochroleucous veined or tinged with dull purple, sometimes bright rose-purple, all strongly incurved through at least a right angle, usually not strongly graduated, the wings (detached) often a trifle longer than the banner but arched in a longer and wider arc and so, in situ, appearing shorter; banner 8-11 mm. long, the shortly cuneate claw abruptly expanded into a broadly ovate, rhombic- ovate, suborbicular, or inversely reniform, shallowly and openly notched or entire blade 5-8.2 mm. wide; wings 8.5-10.5 mm. long, the claws (3) 3.5-5.6 mm., the lunately oblong, oblong-oblanceolate, or obliquely obovate, obtuse, often erose, or sometimes subemarginate blades 3.5-7 mm. long, (1.6) 2-3 mm. wide, their inner margins commonly infolded and once or more undulately notched near the middle; keel 8.1-9.4 mm. long, the claws (3) 3.2-5.4 mm., the lunately triangular, or lunately half-circular blades 4.8-6.1 mm. long, 2.3-3 mm. wide, abruptly incurved through 100-125 degrees to the triangular or sometimes triangular- acuminate, subacute or obtuse, often obscurely porrect apex; anthers 0.55-0.75 mm. long." (bibref: 1813).
Fruit: "Pod essentially pendulous, but spreading vertically from divaricate peduncles and then (in pressed material) apparently horizontal, sessile but sometimes basally attenuate and then appearing very shortly and obscurely stipitate, linear-oblanceolate, beyond middle 3.5-5 mm wide, backwardly attenuate into calyx, straight or a trifle arched either way, 1.3-5 cm. long, 2.3-4 mm. in diameter, laterally compressed, bicarinate by the slender sutures, the faces flat when young becoming distended and low-convex at maturity, the thin, pale green, purplish, or purple-mottled, strigulose valves becoming papery, stramineous, delicately cross-reticulate, not inflexed; dehiscence apical and downward through both sutures, the valves ultimately separating to the base and coiling outward; ovules 13-20; seeds brown or olivaceous, sometimes purple-speckled, smooth and lustrous, or more or less pitted or rugulose and then either dull or shining, 2.5-4.3 mm. long." (bibref: 1813).
