Description and Ethnobotany

Growth Form It is a tree up to 40 m tall.
Foliage Its alternate, stalked leaves possess leaf blades that are thickly membranous to papery, egg-shaped-oblong to oblong-lance-shaped, veins distinctly raised above, light brown or chocolate-brown and hairless below, and 7–28 by 2.5–9 cm.
Flowers The species is dioecious with individual trees producing either male or female flowers. Its flowering shoot (inflorescence) has sparse to dense woolly hairs and is 0.6 mm long. Its male inflorescence is 4–20 by 3–12 cm, and contains flowers in up to 8-flowered clusters. Its female inflorescence is up to 8 cm long. The male or female flowers are hairless or gradually becoming so, jade-green, turning to yellow when mature, and its male flowers are smaller than its female flowers.
Fruits Its fruiting clusters (infructescences) contain 1–6 fruits each. Its fruits are partially round or ovoid, hairless, and are 1.9–6 by 1.4–5 cm.
Habitat It grows in lowland forests, freshwater swamp forests, ridge-top forests, and heath forests, up to 1,100 m altitude. It occurs locally in Bukit Timah Nature Reserve, Central Catchment Nature Reserve (Bukit Kallang, Mandai Forest, and Nee Soon Swamp Forest), and Chestnut Avenue.
