Tree 7.5–9 m. high, apparently evergreen. Bark rough or smooth. Young branchlets tomentellous to puberulous with minute white to brown hairs and with numerous other minute blackish-red opaque worm-like quite possibly glandular hairs intermixed. Leaves: petiole (0.6–)1–1.7 cm. long; rhachis (3.5–)6–12 cm. long, at first with a sparse indumentum like that of the branchlets, glabrescent; leaflets in 3–5(–6, fide Taubert) pairs, ovate-elliptic to elliptic, usually with a subrhombic tendency, 2.5–9(–12.5) cm. long, 1.3–5(–6.5) cm. wide, obtuse to rounded at apex, asymmetric at base, glabrous (unless on midrib when young), with nerves and venation prominent on both surfaces. Racemes ± 9–13 cm. long (to 20 cm. in fruit); axis, pedicels (± 0.6–1 cm. long, and to 1.3 cm. in fruit) and outside of calyx with a dense tomentellous brownish indumentum like that of the branchlets; calyx with some scattered round red sessile glands in addition. Petals yellow, unguiculate, obovate-spathulate, 1.6–2 cm. long, 6–9 mm. wide, obtuse or rounded at apex. Pods obliquely oblanceolate, ± 5 cm. long and 2 cm. wide, olive-brown, glabrous and rather glossy. Seeds broadly obovate-elliptic, ± 14 mm. long and 10 mm. wide, brown, glossy. Fig. 9.
