Morphology General Habit

Straggling and ascending or climbing woody herb or shrub, up to 1–6 m. tall.

Morphology Branches

Branches rather slender, subterete, puberulous and glabrescent.

Morphology Leaves

Leaves 3-foliolate; leaflets elliptic-lanceolate, elliptic or elliptic-obovate, up to 25–46 mm. long, 11–18 mm. wide, glabrous above, appressed puberulous beneath; petiole slender, ± 22–36 mm. long.

Morphology Leaves Stipules

Stipules linear, up to 1–2 mm. long, sometimes obscure.

Morphology Reproductive morphology Inflorescences

Racemes usually lax with a slightly zigzag rhachis, up to 7–18 cm. long, ± 6–16-flowered; bracts linear to subulate, ± 1–3 mm. long; bracteoles inserted near the top of the pedicel, filiform, small.

Morphology Reproductive morphology Flowers Calyx

Calyx 7–10 mm. long, protracted on the lower side, subglabrous to puberulous; upper lobes rather narrowly acuminate-triangular, mostly 1·5–2 times as long as the tube.

Morphology Reproductive morphology Flowers Corolla

Standard broadly elliptic or suborbicular, clear yellow, sometimes lined with brown or purple and turning salmon or purplish with age, glabrous outside; wings ± as long as the keel; keel rather abruptly rounded below the middle, with a well-developed twisted beak, 13–17 mm. long.

Morphology Reproductive morphology Fruits

Pod markedly inflated, broadly ellipsoid-clavate, shortly narrowed into a 7–10 mm. long stipe, up to 45–60 mm. long, 15–22 mm. across, thinly puberulous, glabrescent, developing a prominent vein network, ± 12–20-seeded.

Morphology Reproductive morphology Seeds

Seeds oblique-cordiform, up to 5 mm. long, matt, pale yellow.

Habitat

Margins and clearings of rain-forest; 950–2560 m.
