Leaf: "Stipules 1.5-3 mm. long, those at the lower, leafless nodes early becoming papery, strongly adnate to the suppressed petiole and almost fully amplexicaul but free, the median and upper ones herbaceous, deltoid or triangular-acuminate, mostly deflexed; leaves 3.5-7 cm. long, petioled but the uppermost very shortly so, with 7-11 linear or linear-elliptic, obtuse but mucronulate, flat leaflets (5) 8-20 mm. long, the terminal one usually the longest." (bibref: 1813).
Flower: "Peduncles incurved-ascending, 3-6 cm. long; racemes loosely or at length remotely 10-18-flowered, the flowers early spreading and ultimately declined, the axis elongating, 3-7 cm. long in fruit; bracts membranous, triangular-ovate, 1-1.5 mm. long; pedicels very slender, at anthesis about 1.3 mm., in fruit scarcely thickened, spreading or ascending, 1.5-2 mm. long, persistent or perhaps tardily disjointing with the fruit; bracteoles 0; calyx 3-3.3 mm. long, strigulose with black and partly white or fuscous hairs, the subsymmetric disc 0.7-0.9 mm. deep, the campanulate tube 2.3-2.5 mm. long, 1.8-2 mm. in diameter, the triangular to broadly subulate teeth 0.7-0.9 mm. long, the whole becoming papery, marcescent unruptured; petals whitish, the banner and keel-tip faintly lilac-tinged; banner abruptly recurved through 85-90 degrees, rhombic-ovate-cuneate, openly notched, 6.5-7 mm. long, 4.6-5 mm. wide; wings (a trifle longer or shorter than the keel) 5.3-6.2 mm. long, the claws 2-2.2 mm., the narrowly oblong-elliptic or -oblanceolate, subtruncate, slightly incurved blades 3.5-4.4 mm. long, 1.2-1.5 mm. wide; keel 5.5-5.9 mm. long, the claws 2.2-2.4 mm., the half-obovate blades 3.5-4 mm. long, 1.9-2 mm. wide, abruptly incurved through about 90 degrees to the bluntly deltoid apex; anthers 0.350.5 mm. long." (bibref: 1813).
Fruit: "Pod widely spreading or declined, stipitate, the straight, slender stipe 4-5 mm. long, the narrowly and subsymmetrically oblong-ellipsoid body 8-11 mm. long, 2.4-2.8 mm. in diameter, straight or nearly so, narrowly cuneate- acuminate at base, contracted abruptly at apex into a minute cusp, laterally compressed and 2-sided, the faces low-convex, the sutures slender but salient, the thin, green or faintly purple-speckled or -mottled, minutely strigulose valves becoming stramineous, smooth or nearly so, not inflexed; dehiscence apparently apical and then downward through the ventral suture; ovules 8-10; seeds dark brown, minutely punctate, 2.1-2.5 mm. long." (bibref: 1813).
