Morphology General Habit
Shortly erect annual, with long decumbent lower branches, hirsute with tawny spreading hairs.
Morphology Leaves
Leaves shortly petiolate, 3-foliolate; leaflets very variable, 2.5–7.5(11.5) × 1–2.5 cm, linear-lanceolate to elliptic or obovate, with those of the leading shoot often longer and narrower, conspicuously pilose on both surfaces; stipules up to 3–4 mm long, filiform.
Morphology Reproductive morphology Inflorescences
Racemes mostly terminal, shortly pedunculate, up to 3–17 cm long, densely many-flowered; bracts up to 4 mm long, filiform; bracteoles inserted at the base of the calyx, similar.
Morphology Reproductive morphology Flowers Calyx
Calyx 3–4.5 mm long, becoming basally truncate and deflexed against the pedicel, subglabrous except for scattered bristly hairs along the lobe margins; lobes acuminately triangular, a little longer than the tube.
Morphology Reproductive morphology Flowers Corolla
Standard subcircular, pale yellow, purplish veined; wings usually shorter than the keel; keel 6.5–8.5 mm long, rounded about the middle, with a sharp slightly projecting beak.
Morphology Reproductive morphology Fruits
Pod sessile, 1.6–1.8(2) cm long, subcylindrical, somewhat pointed, densely covered with long brown spreading hairs over a furry tomentum, c. 20-seeded.
Morphology Reproductive morphology Seeds
Seeds c. 2.5 mm long, oblique-cordiform, smooth, pale greenish-buff, mottled greyish-mauve.
