Suffrutex to weakly branched, woody shrub, 0.6-1.5 m tall, filamentously pilose, trichomes often clustered. Stems simple or weakly branched, smooth; pith variable in thickness. Bark weakly to well developed. Leaves with a maximum length of 8-13.5 cm, including distinct petiole up to 2-2.6 cm long, usually widely or deeply sulcate, canaliculate, carinate or semi-terete, base semi-amplexicaul; outline variable, trifoliolate, sometimes pinnately and/or pedately compound with rarely up to 7 divisions; incision usually decursive. Pinnae elliptic to obovate or ovate; apex acute to obtuse or rounded, mucronate up to 6.5-11.5 x 2.5-5 cm; margins crenulate, often undulate, ciliate; base attenuate; abaxial veins often raised above the surface; somewhat tuberculately pilose. Inflorescence a single compound umbel or a lax panicle of compound umbels, inflorescence leaves not reduced in size; main florescence of (24-)28-32 rays, 1.5-3 cm long, and 15-27(-27) raylets, 2-3(-4) mm long, often larger than the lateral umbels. Involucral bracts small to broad and conspicuous (usually more than two foliose bracts). Petals cream-coloured to greenish yellow, higher than, or as high as broad, abaxially bearded, particularly along the keel. Fruit invariably filamentously pilose, elliptic to broadly elliptic, 4-6 x 2-3 mm, with well developed (half-winged) petaline ribs, secondary ribs invariably present, bearded; ±16 irregular vittae surrounding the seed, occasional small vittae also not infrequently occurring in the tips of the ribs or part way along them.
