Tree, 25 m, with small buttresses. Branchlets c. 8 mm thick, lenticellate, young parts densely ferrugineously woolly tomentose; pith with many vascular strands, sometimes arranged into 1 or more concentric cylinders. Stipules (nearly?) always absent. Leaves 4-8-jugate. Leaflets oblong-lanceo-late, 7-16 by 2.5-5(-6) cm, thinly chartaceous, glabrous; base often oblique, cuneate to truncate; margin entire; apex gradually shortly (c. 1 cm), broadly, and bluntly acuminate; nerves 14-17 pairs (angle 60-70°), faintly to strongly curved, gradually, often rather distinctly, arching at 1 mm from the margin. Inflorescences axillary, narrowly paniculate, densely woolly pubescent, glabrescent, ♂ ones 9-27 cm long, ♀ ones 7-15 cm; partial panicles about decussate, patent, rather long-stalked, ♂ ones up to 4-5 cm long, with up to 12 flowers, female ones 2.5 cm long, with 8-10 flowers. Flowers 7-8 mm long, slightly pubescent outside. Calyx 0.25 cm high, nearly truncate. Stamens glabrous, 6-7 mm long, connate for 3-4 mm. Disk pilose, in ♂ flowers subglobose, 1.5-2 mm high, with a central canal, in female flowers cupular, 1 mm high, 6-undulate. Pistil glabrous, in ♂ flowers absent. Infructescences up to 20 cm long, thinly pilose, branches with 1 fruit only; calyx spreading, 0.5 cm diam. Fruits ovoid, round in cross-section, 2.5-3.25 by 1-1.5 cm, glabrous; pyrene ± 6-angular; lids rather thick. Seeds 1-2; sterile cell(s) often very reduced.
