Dioecious trees to 40 m., the younger branchlets densely tomentose to hirsute with ochraceous, usually evanescent hairs. Leaves glabrescent above except for the midrib, with persistent, ochraceous, stalked-stellate hairs below, coriaceous, oblong to narrowly ovate or obovate, apically acuminate or attenuate, basally cordate to acute, 13-38 cm. long, 4-13 cm. broad; secondary veins 18-35 on either side, averag-ing more than 1 per cm. along the midrib, the tertiary veins rather prominent below; petioles canaliculate, 7-16 mm. long, 1.5-4.0 mm. broad. Staminate flowers in few-branched panicles, the pedicels 1-5 mm. long; bracts ca. 5 mm. long, deciduous; perianth tardily 3-parted, 1.5-3.0 mm. long; anthers 3, 0.6-0.9 mm. long, usually connate to the apex, the infra-antheral portion of the androecium 0.5-1.2 mm. long. Pistillate flowers in clusters of 3-7 in racemes to 5 cm. long; pedicels 0.5-3 mm. long; tepals connate, with simple or few-branched hairs, the 1-carpellate ovary with a subsessile obscurely 2-cleft stigma. Fruits 1-5 per inflorescence, on pedicels 5-8 mm. long, the glabrescent ligneous pericarp ultimately dehiscing longitudinally into 2 valves, subglobose to ellipsoid, 18-30 mm. long, 16-21 mm. broad; seed ellipsoid to subglobose, the aril laciniate.
