Small tree or shrub, generally scandent if support available and sometimes with aid of coiled branchlets or peduncles, 3–9(–25) m. tall, ± evergreen; bark purplish-brown (at least when dried) and striate on branches, ultimately brown and rather fibrous.. Branchlets brownish tomentellous, usually soon glabrescent.. Leaves ± 13–30 cm. long; stipules oblong, pointed, 5–6 mm. long, fugaceous; lateral leaflets 6–8(–10) on either side of rhachis, oblong or oblong-elliptic, rarely slightly obovate-oblong, 4–9 cm. long, 2–5.5 cm. wide, rather abruptly rounded or emarginate at apex, very broadly cuneate, rounded or slightly cordate at base, glabrous to pubescent; primary lateral nerves ± 14–20 on either side of midrib.. Panicles on leafy branches, ± 5–15 cm. long, but flowering branches often growing out with leaves all or mostly suppressed forming compound inflorescences up to 40–50 cm. long; flowers congested on ultimate axes, many; axes with dark brown persistent felty tomentum; bracts ovate to oblong-elliptic, 1–3.5 mm. long, caducous; bracteoles near top of short 0.5–2(–3) mm. long pedicel, oblong-elliptic to obovate, ± 1.5–2 mm. long.. Calyx 3.5–5 mm. long, pubescent to tomentellous with short dark brown to almost black hairs, rarely glabrous.. Corolla 6.5–9(–10) mm. long, white flushed mauve to purplish (particularly on standard inside); standard broadly ovate to suborbicular, cordate and very shortly clawed; wings as long as standard and much exceeding keel.. Stamens (9–) 10, partially or wholly divided into 2 subequal phalanges.. Fruit oblong, rather abruptly narrowed or rounded at the ends, with the 0.5–1.5 cm. long stipe (8–)10–15 cm. long, 3–4.5 cm. wide, scarcely thickened over the seed-cavity, chartaceous, greenish or purplish turning dull pale brown or straw-coloured, glabrous, with very laxly reticulate slightly immersed venation..
