Leaves imparipinnate, up to 22 cm long and 20 cm wide; petiole 3.5–7 cm long, petiole, rachis and petiolules densely covered with scales like those on the twigs. Leaflets 5–9, 4–13 by 1.5–5 cm, apex acuminate, cuneate at the slightly asymmetrical base, the upper and lower surfaces sometimes with numerous pits, densely covered with scales like those on the twigs on the midrib of the lower surface and nearly always absent from the rest of the leaflet surfaces; veins 6–13 on each side of the midrib, reticulation often sub– promiaent on both surfaces; petiolules 3.5–7 mm. Inflorescence up to 12 cm long and wide; peduncle 1–2 cm, either with scales like those on the twigs or densely covered with reddish–brown or orange–brown scales on the peduncle, rachis and branches.

Petals 5. Staminal tube c. 1 mm long and wide, ob-ovoid, thickened and adpressed against the ovary below the anthers, the aperture 0.5– 0.8 mm in diam. and shallowly lobed; anthers 5, 0.5–0.7 mm long, 0.3–0.5 mm wide, ovoid, inserted below the margin of the tube and protruding to fill or almost fill the aperture.
