Racemes many-flowered, sessile, up to 5 cm. long but usually much shorter; bracts lanceolate, ± 1 mm. long, caducous; pedicels ± 1 mm. long, strongly reflexed in fruit.. Calyx brown strigulose, ± 1.5 mm. long; lobes triangular, as long as the tube.. Corolla brown strigulose outside.. Stamens 3–4 mm. long.. Pod brown, straight, slightly tetragonal, somewhat torulose, but not in the plane of the sutures, 12–17 mm. long, ± 2.2 mm. wide, up to 2.8 mm. thick; endocarp ± spotted..
