Morphology General Habit
Annual, with an erect stem up to 3–4·5(–13) dm. tall, developing rather numerous weakly ascending, straggling or procumbent laxly subdivided branches, particularly from near the base.
Morphology Branches
Branches slender, sparsely appressed or rarely slightly spreading pubescent.
Morphology Leaves
Leaves 1-foliolate; leaflets mostly linear-lanceolate to lanceolate, up to 45–70 mm. long and 4–10(–15) mm. wide, or the lowermost sometimes shorter and elliptic, glabrous above, thinly appressed pubescent beneath; petiole up to 4–8(–11) mm. long.
Morphology Leaves Stipules
Stipules filiform, 0·5–1·5 mm. long.
Morphology Reproductive morphology Inflorescences
Racemes long and slenderly pedunculate, up to 9–24 cm. long, with ± 4–8 very laxly arranged flowers; bracts subulate-filiform, 1–2·5 mm. long; bracteoles inserted at the base of the calyx, filiform, 0·5–2 mm. long.
Morphology Reproductive morphology Flowers Calyx
Calyx 3–4 mm. long, thinly appressed puberulous; lobes narrowly attenuate-triangular, usually a little longer than the tube.
Morphology Reproductive morphology Flowers Corolla
Standard suborbicular, clear yellow, veined reddish-brown or purple and glabrous outside; wings obovate-oblong, longer than the keel; keel abruptly rounded below the middle, with a blunt or acute incurved beak, 4·5–6·5 mm. long, pale greenish-yellow, rarely with dark veins.
Morphology Reproductive morphology Fruits
Pod practically sessile, subcylindrical, up to 11–24 mm. long and 6–8 mm. across, thin or thick-walled, thinly pubescent, ± (10–)20–26-seeded.
Morphology Reproductive morphology Seeds
