A tree to 25 m. tall, often with an unbranched bole up to 12 m. tall and 1.2 m. diameter. Leaves up to 55 cm. long, imparipinnate, less frequently paripinnate; leaflets (3–)4–5(–6) pairs, coriaceous, rarely chartaceous, lanceolate to narrowly ovate, very occasionally rotund, often straight-edged or oblique, up to 14.5 cm. long by 6.5 cm. wide (or larger in saplings), acute to acuminate, rarely emarginate, with a rounded to cordate (often subcordate) base, with the margins entire, often very narrowly inrolled, densely stellate-tomentose when young, later glabrescent to some extent, especially above where occasionally glabrous; petiolules of paired leaflets (0–)2–5(–14) mm. long. Inflorescence-branches puberulous to tomentose; primaries up to 40 cm. long by 2.5–4.0 mm. diameter; secondaries up to 2.7 cm. long by 0.8–1.2 mm. diameter, both orders racemosely borne; tertiaries (pedicels) up to 9 mm. (commonly 2–5 mm.) long by 0.5–0.8 mm. diameter in umbellules. Fruits flattened-ovoid, -ellipsoid, -cylindrical or ± spheroidal, 4.0–7.5 mm. long, ribbed, apart from the stylopodia and persistent styles densely (often interruptedly) covered with stellate hairs.
