Description

Tree 3-20(-30) m, without buttresses. Leaves chartaceous to subcoriaceous, oblanceolate or narrowly elliptic to narrowly obovate or narrowly elliptic-oblong, 3-35 x 1.5-14 cm, apex long- to short-acuminate to apiculate or rarely rounded, base narrowly attenuate-cuneate, glabrous except often puberulous on midvein and secondary veins especially below; domatia absent or shallow except for dense hair-tufts; venation eucamptodromous or eucamptodromous-brochidodromous, midvein moderate to strong, prominent, secondary veins 6-14 pairs, moderately spaced to distant, arising at moderately acute angles, curved, prominent, intersecondary veins usually absent; tertiary veins regularly and often closely percurrent, higher order veins distinct; areolation imperfect, slightly prominent; petiole 0.6-3.5 cm long, pubescent to sparsely so, biglandular (often conspicuously so). Inflorescence 3-13 cm long, spicate; peduncle 0.6-3.2 cm, puberulous to densely so; rhachis 2-10 cm, densely puberulous. Flowers 2.5-3.5 mm long; lower hypanthium 1.5-2 mm long, densely pubescent on ovary-bearing part, with glabrous to sparsely pubescent neck ca. half total length; upper hypanthium 1-1.5 x 2.5-4 mm, glabrous or nearly so. Fruit densely fulvous-pubescent, 1-3.3 x 0.6-1.3 cm, elliptic to oblong or narrowly so in side view, more or less terete, apex rounded to subacute or apiculate, base rounded to very shortly pseudostipitate.
