Shrubs or small trees, 1-6 m tall; branches glabrous, blackened becoming yellowish white or grayish white with age. Petiole 4-18 mm, glabrous; leaf blade drying papery or leathery, dark brown or sometimes yellowish brown abaxially, and somewhat shiny adaxially, elliptic-obovate, elliptic, or subovate, 4-15 × 2-6.5 cm, both surfaces glabrous, base cuneate or acute, apex shortly acuminate often abruptly acuminate with tip often slightly obtuse; secondary veins 5-11 pairs, without domatia; stipules deciduous usually through fragmentation, shortly united around stem, triangular-ovate, 1.5-3 mm, glabrous, resinous, acute. Inflorescences corymbiform to pyramidal, 2.5-3 × 3-5 cm, few to many flowered, puberulent, hirtellous, or glabrescent, subsessile to pedunculate; peduncle to 1 cm; bracts triangular, 0.3-1.5 mm; pedicels 0-3 mm. Flowers mixed sessile and pedicellate (or perhaps borne on expanded axes) in dichotomous cymules. Calyx glabrous, puberulent, or pilosulous; hypanthium portion cupuliform to ellipsoid, ca. 1 mm; limb ca. 1 mm, lobed for 1/2-3/4; lobes ovate or triangular, ciliolate, acute to rounded. Corolla white, outside glabrous; tube 3-4 mm, villous inside and at throat; lobes narrowly oblong to spatulate, ca. 5 mm, acute to obtuse. Ovules 1-3 per cell. Berries globose, 6-8 mm in diam., shiny, glabrescent; seeds 1 or 2. Fl. Apr-Nov, fr. Apr-Jan.
Forests or thickets at streamsides, on hills, or on mountain slopes; 200-1700 m. Guangdong, Guangxi, Guizhou, Jiangsu, Yunnan [Vietnam].
