Morphology General Habit
Erect or straggling-ascending annual, up to 9 dm. tall, much branched.
Morphology Branches
Branches thinly pilose or (not in East Africa) appressed pubescent.
Morphology Leaves
Leaves 3-foliolate; leaflets elliptic or ovate-elliptic, up to 4·5–7 cm. long, 2·3–4 cm. wide, acute, sparsely pilose on both surfaces; petiole up to 3·3–6·5 cm. long.
Morphology Leaves Stipules
Stipules filiform, up to 7 mm. long.
Morphology Reproductive morphology Inflorescences
Racemes very lax, up to 10–17 cm. long, ± 3–10-flowered; bracts lanceolate, up to 10 mm. long, 4 mm. wide; bracteoles curved-ascending from the upper part of the pedicel, ovate, cordate, up to 10 mm. long.
Morphology Reproductive morphology Flowers Calyx
Calyx practically enveloping the corolla, 10–12 mm. long, ciliate on the lobes, otherwise glabrous; upper lobes broadly ovate, cordate, rather unequal-sided, very much longer than the tube.
Morphology Reproductive morphology Flowers Corolla
Standard suborbicular, clear yellow, sometimes tinged bluish or red behind and at the base inside, glabrous outside; wings broadly oblong-obovate, as long as the keel; keel strongly rounded about the middle, with a slightly incurved shortly twisted beak, 8–10 mm. long, white lanate-pubescent along the upper margin proximal to the beak.
Morphology Reproductive morphology Fruits
Pod subcylindrical, broadest towards the apex and basally narrowed into a 5–9(–15) mm. long stipe, 36–45 mm. long, 9–12 mm. across, glabrous, thin-valved, with only 8–10 of the 40–50 ovules matured.
Morphology Reproductive morphology Seeds
Seeds oblique-cordiform, up to 3 mm. long, smooth, yellowish-brown.
