Trees, deciduous, to 30 m tall; trunk with small buttresses; bark thin, grayish brown, fissured and scabrous when old; branches horizontally spreading, flattened becoming subterete, glabrescent. Petiole 20-35 mm, glabrous; leaf blade drying thinly leathery, elliptic or oblong-elliptic, on juvenile growth 50-60 × 15-30 cm, on adult growth 15-25 × 7-12 cm, adaxially shiny and glabrous, abaxially glabrous to densely puberulent, base shallowly cordate on juvenile growth, rounded or truncate on adult growth, apex acute; secondary veins 8-12 pairs, apparently without domatia; stipules lanceolate, 12-20 mm, acute. Inflorescences with peduncle 2-4 cm, rather stout; flowering heads 35-45 mm across calyces, 40-60 mm across corollas. Calyx puberulent to pilosulous; ovary portion ellipsoid to obovoid, ca. 1.5 mm; limb 3-4 mm, partially to deeply lobed; lobes oblong to spatulate, obtuse to rounded. Corolla yellowish white, funnelform, outside glabrous; tube ca. 10 mm; lobes lanceolate, ca. 2.5 mm. Fruiting heads yellowish green, 30-40 mm in diam., with peduncles markedly thickened. Fruit cylindrical to ellipsoid or obovoid, 2-2.5 × ca. 1 mm, glabrous; seeds 3-angled, 0.5-0.7 mm. Fl. and fr. Jun-Nov.
Broad-leaved forests, streamsides in valleys. Guangdong, Guangxi, Yunnan [Bhutan, India, Malaysia, Myanmar, Sri Lanka, Thailand, Vietnam].
This species is occasionally cultivated for lumber in Asia, including probably in China, and in the Neotropics.
