Trees, ca. 10 m tall; branches terete to subquadrangular, densely brown hirtellous to glabrescent. Leaves opposite; petiole 0.5-1.2 cm, densely hirtellous to strigillose; blade drying subleathery, obovate, obovate-elliptic, or rarely elliptic, 6.4-11.5 × 3-6.5 cm, adaxially sparsely hispidulous to puberulent with pubescence denser along midrib, abaxially sparsely to moderately strigillose or hirtellous with pubescence denser along veins, base obtuse, apex acute to abruptly and shortly acuminate; secondary veins 6-8 pairs, plane to hardly visible abaxially; stipules generally persistent, pandurate, 3-5 × 1.5-2 mm, densely strigillose, apex suberect to spreading, subrounded. Inflorescences paniculate, 7-10 × 4-5 cm, branched to 2 or 3 orders, dark yellow- to reddish brown tomentose to -hirtellous, pedunculate; peduncle 0.5-0.8 cm; bracts linear to narrowly elliptic, 1-3 mm. Flowers sessile, densely grouped. Calyx densely hirtellous; hypanthium portion subglobose, ca. 0.8 mm; limb lobed nearly to base; lobes triangular to ovate, ca. 0.5 mm. Corolla pale yellow, tubular-funnelform, glabrous outside; tube 2.5-3 mm, sparsely pilose in throat; lobes ovate, ca. 1 mm. Anthers elliptic, ca. 0.7 mm, subsessile, partially exserted. Stigma 2-lobed, ca. 0.2 mm. Capsules subglobose to ovoid, ca. 2 × 2 mm, hirtellous. Fl. and fr. Jun.

● Forests on mountains or hills; ca. 800 m. Guangxi (Tianlin).

This species was included by How (loc. cit.) and W. C. Chen (Acta Phytotax. Sin. 21: 391. 1983) in the group of Wendlandia species with erect, triangular, acute stipules; but examination of an isotype (MO!) and careful study of the protologue (including the figure) shows that the stipules are oblanceolate to pandurate, with the apex narrow but mostly not spreading from the stem on most nodes.
