Shrubs or trees, 2-12 m tall; branches terete to flattened, densely tomentulose, pilosulous, or hirtellous with pubescence drying ferruginous, sometimes becoming glabrescent with age. Petiole 5-15 mm, densely hirtellous or pilosulous; leaf blade drying thinly leathery or papery, often reddish brown, elliptic-oblong, oblong-lanceolate, or oblong-oblanceolate, 8-27.5 × 2-10 cm, adaxially glabrous and slightly shiny, abaxially hirtellous or pilosulous with pubescence usually denser on principal veins, base cuneate to obtuse and sometimes slightly inequilateral, apex acuminate to caudate-acuminate with tip to 2.5 cm and sometimes falcate curved; secondary veins 10-14 pairs, in abaxial axils sometimes with weakly developed pilosulous domatia; stipules deciduous or sometimes persisting on apical 2 or 3 nodes, interpetiolar, lanceolate to narrowly triangular, 8-12 mm, densely strigillose to hirtellous or tomentulose, apex acute to acuminate. Inflorescences cymose with axes markedly dichasial, many flowered, 4-6 × 5-12 cm, branched to several orders, densely hirtellous to pilosulous or tomentulose; peduncle 0.5-1.5 cm; bracts linear-lanceolate, 2-4 mm, acute; pedicels 1-4 mm.
