Trees, dioecious. Twigs lenticellate, flaky, crowded scars of cataphylls at base of innovations usually present. Leaves brittle when dry, lower surface pale, papillose, dots absent; reticulation faint. Inflorescences (synflorescences) below the leaves, a compound panicle-like short-shoot 1-5 cm long, ending in a vegetative bud; partial inflorescences pedunculate, with flowers in subumbels of 5-10 in male, fewer in female; basal cataphylls absent; bracts caducous. Flowers long pedicellate, bracteole absent. Male flowers: perianth ± urceolate, leathery, inside glabrous except at base of androphore, creamy (?); buds ovoid, 5-7 mm long, cleft for 1/3 to nearly halfway, lobes 3, not reflexed in anthesis; androecium 4(-4.2) mm long, androphore slender, 1.5-2 mm long, glabrous, except for a dense collar of fine hairs at base, synandrium of c. 20 completely fused linear anthers, subglobose, 2-2.4 mm diameter, the central column deeply and broadly excavated nearly to the base. Female flowers not known. Infructescences 2-5 cm long, with 2-6 fruits. Fruits ovoid-ellipsoid, 4-5.5 cm long, woolly tomentose; pericarp ± thick, ± woody; aril laciniate to the base; seeds ellipsoid-oblong, 3 cm long, not variegated; cotyledons not known.
