Treelet 4 m. Twigs 5-6 mm diameter, smooth, hardly striate, bright brown, subterete with shallow lines from petiole to petiole, partially hollow (see field-notes) but ant-holes not seen, glabrous (glabrescent, but twig apex not seen); older twigs not seen; lenticels small, scattered, inconspicuous. Leaves membranous, obovate-oblong, 22-32 by 8-15 cm, base cuneate, apex broadly rounded with acute-acuminate tip; upper surface green-olivaceous, lower surface pale, subglabrous, hairs extremely minute, scattered, whitish, appressed; minutely irregularly papillose; dots absent; midrib almost flat above, lateral nerves 20-22 per side, at 70-80° to the midrib, flat, lines of interarching and venation slender, distinct at both surfaces; petiole 25-30 by 3 mm, glabrous; leaf bud not seen. Male inflorescences between the leaves, of the Knema-type: sessile, scar-covered brachyblasts to 5 mm diameter, the flowers in subumbels of 2-5, buds slightly variable in size, with ± scattered mealy stellate hairs (less than) 0.1-0.2 mm. Male flowers: pedicel 7-8.5 by 2.5(-3) mm, bracteole scar at about 1/3-1/2 from the apex; buds firm, oblong-fusiform, 15-16 by (4-) 5-6 mm, broadest above the middle, apex acute, base tapered, apical part triangular with lines of lobe sutures clearly marked, cleft c. 1/3, lobes (4-)5 mm long, 0.6-0.8 mm thick. Androecium 12-13 mm; androphore 4 by 1.5-2 mm, appearing to be glabrous but with very minute (less than 0.1 mm) pale stellate hairs in the lower 2/3; synandrium oblong, acute, 8 by 3 mm, thecae 24-26, sterile apex 0.5-1 mm long.
