Trees, 6-30(-40) m tall, buttressed; bark smooth to coarse; branchlets brown, angular to terete, puberulous to glabrous. Stipules linear-lanceolate, 1.5-3 mm, glabrous or glabrescent, early caducous; petiole 5-12 mm, glabrous or finely hairy; leaf blade variable in shape and size, elliptic to oblong, rarely obovate, excluding acumen 1.5-2.5(-3) × as long as broad, 6-18(-20) × 2.5-8(-9) cm, thinly leathery to thickly papery, abaxially pubescent with appressed short hairs or glabrous, adaxially glabrous or ± glabrescent, midvein raised abaxially, flat or impressed adaxially, lateral veins 7-10 pairs, raised abaxially, base acute with concave sides, acute-cuneate, or subrounded, margin serrate-crenate to practically entire, teeth apices obtuse, leaf apex acute to rounded, contracting (sometimes very abruptly) to an acumen to 1 cm. Inflorescence axillary, racemose, pendulous, 5-20(-30) cm; rachis sparsely to very densely, pale grayish brown shortly pubescent; bracts narrowly triangular, minute, to ca. 2 mm, papery, sparsely hairy, caducous. Pedicels 1-3 mm, articulate at or above middle, densely puberulous to appressed shortly pubescent. Flowers numerous, in fascicles of 3 to ca. 20, sometimes very crowded along rachis, reddish or whitish, 4-6-merous, 2.5-3 mm in diam. at anthesis, fragrant. Calyx tube 0.5-1.5 mm, sparsely to densely pubescent, hairs whitish, appressed, short (0.1-0.2 mm); sepals linear-oblong or spatulate, 0.5-2 × 0.3-0.5 mm, apex acute, indumentum outside as for calyx tube, inside slightly denser, margin densely ciliate, hairs spreading, whitish, length less than 1/2 to 1 × sepal width. Petals whitish or pinkish, ovate-oblong or spatulate, 0.8-2 × ca. 0.6 mm, both surfaces densely appressed whitish pubescent, sometimes more so than sepals, margin densely white-ciliate, apex obtuse. Disk glands truncate at apex, hairy. Stamens 4-6; filaments 2-3 mm, glabrous; anthers ca. 0.4 mm. Free part of ovary gray pubescent; placentas 4-6, each with 3-6 ovules; styles 4-6, free nearly to base, 1-2 mm, sparsely hairy at base; stigmas capitate to slightly peltate. Mature fruit not seen. Fl. Jan-Nov, fr. Feb-Dec.
