Description from Flora of China

Columbia floribunda Wallich ex Kurz, J. Asiat. Soc. Bengal, Pt. 2, Nat. Hist. 42: 63. 1873.

Trees 8-10 m tall. Branchlets gray-brown stellate puberulent. Petiole 1.5-5.5 cm; leaf blade broadly obovate-orbicular or nearly orbicular, 14-21 × 11-20 cm, with rough, gray-brown stellate hairs on both surfaces, more dense abaxially, basal veins 5-7, veinlets prominently raised abaxially, base slightly cordate, margin serrulate, apex acute or acuminate, sometimes 3-5-lobed. Inflorescences terminal, to 27 cm. Flowers ca. 8 mm in diam. Sepals lanceolate, ca. 4 mm, stellate tomentose abaxially. Petals yellow, spatulate, nearly as long as sepals. Stamens ca. 40, nearly as long as petals, in 5 bundles. Ovary stellate tomentose, 3-5-loculed; stigma hairy. Capsule 1-1.5 cm in diam., stellate hairy, 3-5-winged, wings ca. 5 mm. Fl. Jun, fr. Nov.

The basionym is often given as "Grewia floribunda Wallich ex Voigt" (Hort. Suburb. Calcutt. 128. 1845) but that name, as a nomen nudum, was not validly published.

Secondary montane forests; 300-2000 m. S Yunnan [India, Laos, Myanmar, Thailand, Vietnam].
