Tree, up to c. 50 m by 120 cm, with short thick buttresses. Trunk sometimes armed with small spines (KERR 18791). Branchlets stout, c. 12 mm thick, glabrous but for the tomentose terminal bud; pith with a peripheral cylinder of small vascular strands closely appressed to the wood. Stipules absent. Leaves 6-14-jugate, up to 1.30 m long, glabrous. Leaflets narrowly lanceolate, 7-26 by 3-8½ cm, stiff-chartaceous; base slightly oblique, rounded to subcordate, often slightly decurrent; margin entire; apex gradually, long (c. 1 cm) and slender blunt-acuminate; nerves c. 16-25 pairs (angle c. 55°), straight to slightly curving, close to the margin strongly curving and indistinctly arching. Inflorescences (female unknown) axillary, narrowly paniculate, 20-30 cm long, glabrous, partial panicles nearly decussate, patent, up to 2 cm long, shortly stalked, laxly cymose, many-flowered; bracts small, triangular. Flowers (female unknown) 1 mm pedicelled, 7 mm long, slender. Calyx 2 mm high, (sub)-glabrous. Petals outside towards the top slightly rugose. Stamens glabrous, unequally high confluent at the base (c. 2-4 mm). Disk tubular, 1 mm high, thick-fleshy, on the rim and the inner side densely pilose; no pistil. Infructescences unknown. Fruits ovoid, round in cross-section, 5 by 2.5 cm, glabrous; pericarp rather thick; pyrene with blunt angle-ribs, lids very distinct, each with an acute median rib; lids 2.5 mm thick.
