Shrubs or trees, 4-6 m tall; branches terete, moderately to densely hirsute. Leaves opposite; petiole 0.3-1.2 cm, moderately to densely hirtellous; blade drying thickly papery, lanceolate-oblong or ovate-elliptic, 7-16 × 3-8.5 cm, adaxially sparsely strigillose or puberulent to glabrescent on lamina and moderately to densely strigillose or hirtellous on principal veins, abaxially sparsely to moderately hirtellous throughout, base rounded to obtuse, apex obtuse, shortly acuminate, or acute; secondary veins 7-11 pairs; stipules generally persistent, pandurate, 5-6 × 4-6 mm, glabrescent, with upper part spreading to reflexed, apex rounded to obtuse. Inflorescences paniculate, branched to 2 or 3 orders, 13-17 × 10-20 cm, densely hirtellous to hirsute, pedunculate; peduncle 1-2 cm; bracts narrowly elliptic to oblanceolate, 1.5-3 mm. Flowers sessile in glomerules. Calyx glabrous; hypanthium portion subglobose, ca. 0.8 mm; limb divided nearly to base; lobes lanceolate or narrowly oblong, 1.2-2 mm, sparsely to densely ciliate. Corolla white or greenish yellow, tubular to salverform, glabrous outside; tube 2-3.5 mm, in throat white hirsute; lobes suborbicular, ca. 1 mm. Anthers elliptic, ca. 0.7 mm, subsessile, partially exserted. Stigma 2-lobed, ca. 0.3 mm. Capsules subglobose, ca. 1.5 mm in diam., glabrous. Fl. Mar-Apr, fr. May.
● Thickets or forests in ravines or on hill slopes; 100-800 m. Guangdong, Hainan.
The ciliate filaments on the margins of the calyx lobes give the appearance of pilose pubescence on all of the calyx at first glance, but when teased apart the individual hypanthia on the material seen are completely glabrous.
