Morphology General Habit
Annual, with a suberect stem up to 3·5 dm. tall, developing rather numerous weakly ascending or spreading branches, particularly from near the base.
Morphology Stem
Stem slender, sparsely appressed puberulous, glabrescent.
Morphology Leaves
Leaves shortly petiolate, 1-foliolate; leaflets lanceolate or linear-lanceolate, up to 35–95 mm. long and 3–16 mm. wide, glabrous above, sparsely appressed puberulous beneath; petiole ± 4–7 mm. long.
Morphology Leaves Stipules
Stipules filiform or subulate, ± 0·5–1·5 mm. long.
Morphology Reproductive morphology Inflorescences
Racemes long and slenderly pedunculate, up to 9–23 cm. long, with ± 4–8 very laxly arranged flowers; bracts linear-subulate, ± 1–1·5 mm. long; bracteoles inserted at the base of the calyx, small, inconspicuous.
Morphology Reproductive morphology Flowers Calyx
Calyx 3–3·5 mm. long, appressed puberulous; lobes attenuate-triangular, ± as long as the tube.
Morphology Reproductive morphology Flowers Corolla
Standard suborbicular, yellow, veined reddish-brown and glabrous outside; wings elliptic-oblong, slightly falcate, a little longer than the keel; keel rounded below the middle, with a very short blunt slightly incurved untwisted beak and a small horn-like protuberance projecting from the leading edge, 6–7 mm. long.
Morphology Reproductive morphology Fruits
Pod subsessile, oblong-ellipsoid, ± 17–18 mm. long and 8–9 mm. across, not thick-walled, dehiscent, soon glabrescent except for small hairs along the upper suture, ± 18–24-seeded.
Morphology Reproductive morphology Seeds
Mature seeds unknown.
