Morphology General Habit
Annual or short-lived perennial, with a well-branched erect leading shoot, up to 6 dm. tall, and long procumbent lower branches.
Morphology Stem
Stem hirsute with rather long spreading hairs swollen at the base.
Morphology Leaves
Leaves 3-foliolate; leaflets linear-lanceolate, lanceolate or elliptic, up to 54–90 mm. long, 11–25 mm. wide, with a few scattered hairs or glabrous above, sparsely pilose beneath; petiole up to 15–30 mm. long.
Morphology Leaves Stipules
Stipules filiform, up to 5–13 mm. long.
Morphology Reproductive morphology Inflorescences
Racemes lax, up to 9–15 cm. long, mostly 4–9-flowered; bracts subulate or filiform, 2–3·5 mm. long; bracteoles curved-ascending from the pedicel, obliquely lanceolate or oblong-falcate, 7–12 mm. long, 3–5 mm. wide.
Morphology Reproductive morphology Flowers Calyx
Calyx practically enveloping the corolla, slightly accrescent, 14–20 mm. long, thinly appressed puberulous and also with long hairs on the tube and lobe-margins; upper lobes ovate, cordate, 4–5 times as long as the tube.
Morphology Reproductive morphology Flowers Corolla
Standard suborbicular, clear yellow, veined sepia near the base inside, pubescent outside; wings as long as the keel; keel bent almost at right-angles in the lower half, with a rather long tapering almost straight untwisted beak, 12–14 mm. long, densely lanate-pubescent along the upper margin.
Morphology Reproductive morphology Fruits
Pod shorter than the calyx, subsessile, broadly ellipsoid, up to 17 mm. long, 10 mm. across, glabrous, ± 22–26-seeded.
Morphology Reproductive morphology Seeds
Seeds oblique-cordiform, ± 4 mm. long, rugose, with the raised areas in concentric rows towards the margin, radial towards the hilum, orange red, with a white “blister” at the narrow end.
Habitat
Deciduous bushland and secondary deciduous woodland, persisting on roadsides and cultivated ground; 850–1600 m.
Distribution
T5 T7 not known elsewhere
