Evergreen tree (6–) 12–45 m. tall; young stem ± appressed-pubescent, glabrescent (first year stem scattered-hirsute). Leaves petiolate; petiole 3–8 mm. long, indumentum similar to stem; blade narrowly to almost broadly elliptic or more rarely obovate, usually c. 5 × 3 cm., exceptionally c. 10 × 5 cm., cuneate or subrounded to an acute base, shortly to longly acuminate or rarely rounded, extreme apex very usually obtuse, margin ± widely bluntly or sharply serrate, especially above, to rarely entire, glabrous above, ± sparsely and obscurely appressed-pubescent beneath especially on the midrib, hairs thin, lying regularly in the direction of the apex, glabrescent, papery to chartaceous. Flowers 1–5 (–8) per inflorescence; pedicels up to 4 mm., rarely 7 mm. long, articulate above the middle, densely puberulous. Calyx 4–5 (–6)-partite; tube 1 mm. long; lobes 3.5–5 mm. long, narrowly oblong-triangular, apex acute, densely appressed-pubescent externally, glabrous or very nearly so within. Petals 4–5, laciniate apically. Stamens (15–) 16–20 (–22), arising from the margin of a very short disc; anthers introrse. Ovary superior, 3 (–4)-celled, glabrous or almost so with a few apical hairs to longly hirsute especially towards the apex; style persistent. Capsule ovoid, 6.5–8 mm. long, shortly appressed-pubescent especially above the middle, with longer upright hairs apically, glabrescent, rarely glabrate. Capsule longer than the persistent style.
