Stipules subulate, 1–4 mm. long; leaf-rhachis up to 4 cm. long including a petiole of 2–15 mm., prolonged 2–8 mm. beyond the lateral leaflets; leaflets 5–11, narrowly elliptic-oblong, up to 25mm. long and 10 mm. broad. Racemes many-flowered, ± secund, usually dense, up to 10 cm. long including a peduncle of up to 3 cm.; pedicels up to 1.5 mm. long. Calyx dark brown, with triangular-subulate teeth up to half as long as the 2.5–3.5 mm. long filaments. Pod spreading or somewhat ascending, cylindrical, 3–7 mm. long, 2 mm. wide, the multicellular hairs, when present, pale, 1- or more often 2-seeded; endocarp hardly spotted. Seeds yellowish, smooth.
