Leaflets 5–7(9), up to 10(25) × 4(8) cm., sessile, chartaceous, glabrous or with a few scattered hairs, oblanceolate (to lanceolate) or ovate (to obovate); apex long-acuminate; base cuneate to narrowly cuneate (sometimes almost creating the impression of a distinct petiole); margins crenate-serrate to subentire.
Inflorescence a group of up to 12 spike-like racemes, up to 35 cm. long in fruit.
Leaves digitately compound; petioles glabrous, commonly up to 20 cm. long but lengths of 53 cm. have been recorded.
Stylopodium well developed, broadly conical; styles short, with shortly recurved stigmatic surfaces.
Flowers distinctly pedicellate, pedicels 3–5 mm.
Fruit hemispherical, up to 6 mm. long, glabrous to very slightly puberulous.
Base of racemes densely clothed with overlapping bracts; floral bracts lanceolate (to ovate).
A tree to 45 m. tall with greenish-grey fissured bark.
Fruits up to 6 mm. long, usually obconical to hemispherical, glabrous or puberulous.
Leaves digitately compound; petiole up to 53.5 cm. long and 5 mm. diameter, but generally considerably smaller, glabrous apart from some crisped hairs in stipular region and at junction with leaflets; leaflets 5–7(–9), sessile, chartaceous to coriaceous, lanceolate to oblanceolate, narrowly ovate and narrowly obovate, up to 25 cm. long by 8 cm. wide, but generally considerably less, caudate to acute (very rarely emarginate), with a narrowly cuneate to much attenuated base (occasionally base only a winged petiolule of up to 12 mm. long), with crenate to subentire margins, glabrous above, glabrous to slightly puberulous beneath.
Flowering spikes up to about 12 together, up to 34 cm. long; floral bracts lanceolate to broadly ovate, up to 3.5 mm. long by up to 2 mm. wide, frequently much smaller, puberulous, sometimes glabrescent quite early on; base of spike-rhachis often clothed with larger, thicker overlapping sterile bracts.
