Tree 6-15 m; branchlets ferrugineous-tomentose at the tips, soon glabrous and covered with numerous, pale, oblong lenticels. Leaves elliptic or oblong-elliptic, rarely oblong, ½-1 cm subacutely or obtusely acuminate at the apex, cuneate to rounded at the base, dark brownish and little shining when dry, chartaceous, glabrous above except the nerves, ± densely rufous-tomentose initially beneath, specially on midrib and nerves, entirely glabrescent at maturity the midrib and domatia excluded, entire or minutely distantly denticulate, ± conspicuously pellucid-punctate, not pellucid-lineate, (6-)8-13(-15) by (3-)4-6.5 cm; midrib slightly impressed above, strongly raised beneath, nerves 8-9 pairs, ± curved and parallel, reticulations rather dense and little, but visibly raised on both faces; petiole pubescent, c. 5 mm.
