Tree, up to 18 m by 30 cm ø. Branchlets 5-7 mm ø, long remaining fulvous-tomentellous; pith with many vascular strands, partly peripheral. Leaves 2-4-jugate. Stipules attached on the base of the petiole, mostly partly on the twig, oblong to reniform, 15-25 by c. 10 mm, rather stiff, persistent. Leaflets ovate to ovate-oblong or elliptic, 3.5-16 by 1.5-10 cm, stiff-coriaceous, beneath thinly puberulous, further glabrous; base of laterals slightly oblique, cuneate to rounded, margin entire, apex rather abruptly, bluntly to acutely acuminate; nerves 7-14 per side, angle to midrib c. 60-70°, nearly straight to curved, looped and joined near the margin, veins and veinlets much more slender, but well-visible on both sides. Inflorescences terminal, c. 25 cm long. Flowers: female unknown. Calyx 5 mm high, outside puberulous, inside glabrous. Petals outside hairy in the central part. Stamens 3, adnate to the disk. Disk solid, globular, tapering into a 'style', glabrous. Infructescence c. 10 cm long, glabrous; calyx flat, orbicular, 1-1.5 cm ø, with inside an annular, not-lobed, glabrous disk. Fruits ovoid to ellipsoid, 5-5.5 by c. 2¾ cm, in cross-section blunt-triangular; pyrene rather smooth; lids 3-4 mm thick. Seed 1, the fertile cell orbicular in cross-section, the sterile ones nearly completely reduced.
