A loosely branched, small, spreading, unarmed shrub or tree 3–12 m. tall; bark green, the outer layers peeling off in small yellowish flakes; slash smooth, pale; exudate slightly resin-scented; twigs pubescent, fluted, ± 4 mm. in diameter.. Leaves 11–17(–19)-foliolate, up to 24 cm. long, including a petiole ± 3 cm. long, pubescent or glabrescent: leaflets sometimes oblong-elliptic and shortly acuminate, sometimes ovate and drawn out into long acuminate tips, always rounded at the base, the largest near the middle of the leaf, up to 41 mm. long and 23 mm. wide, with 4–5 principal lateral veins and up to 20 rather regular sharp serrations on each side of oblong-elliptic leaflets, 8–10 serrations on ovate leaflets.. Male inflorescence paniculate, up to 19 cm. long, sparsely pubescent with 0.2–0.3 mm. long non-glandular hairs and, especially on the pedicels, snorter (up to 0.1 mm.) glandular hairs; the peduncle up to 55 mm. long; bracts linear-lanceolate or spathulate and subfoliaceous, up to 10 mm. long and 1.7 mm. wide; pedicels up to 37 mm. long; receptacle a cup ± 0.8 mm. deep and 1.3 mm. wide; calyx puberulous or glabrescent, the tube ± 0.5 mm., the lobes lanceolate, 2.5 mm. long; petals glabrous, linear-oblong, 4.7 mm. long; filaments 3 and 1.5 mm., anthers 0.7 and 0.6 mm. long.. Female inflorescences shorter, up to 6 cm. long, the peduncles 12–30 mm., pedicels up to 25 mm. long; calyx as in the ♂; petals 4.5 mm.; staminodes 1.3 mm. long; ovary glabrous or pubescent, tapering into a ± 2 mm. long style; stigma capitate.. Fruits borne singly (i.e. each ♀ inflorescence producing a single fruit) on stalks 13–50 mm. long, minutely puberulous or glabrescent, described as shiny, ovoid and shortly beaked, ± 19 mm. long (including the 3 mm. beak), × 13 × (3 + 5) mm.; pericarp 2-valved ± 1.5 mm. thick; pseudaril cupular; stone smooth, appearing triquetrous as the sterile locule is humped, ± 9 × 6 × (3 + 3)..
