Branchlets green-brown, robust, terete; young branchlets gray-green, angled, glabrous. Buds ovoid; bud scales suborbicular, sericeous. Leaves alternate; petiole 1.5-3 cm, concave-convex, glabrous; leaf blade greenish or glaucous green abaxially, dark green and shiny adaxially, usually elliptic-ovate or narrowly elliptic-ovate, 6-12 x 3-6 cm, those on fertile branchlets smaller, leathery, glabrous on both surfaces, pinninerved, lateral veins 4 or 5 pairs, lateral veins and midrib conspicuous on both surfaces, axils of lateral veins inconspicuously dome-shaped abaxially and inconspicuously bullate adaxially, transverse veins and veinlets reticulate, base cuneate or broadly cuneate, margin entire, apex usually acute or shortly acuminate. Panicle axillary on upper part of branchlet or subterminal, 4.5-8 cm; peduncle 3-5.5 cm, peduncle and rachis glabrous. Pedicels slender, up to 4 mm, glabrous. Flowers green-yellow, small, ca. 3 mm.

Ecology
In undisturbed to disturbed mixed dipterocarp and sub-montane forests up to 1700 m altitude. Usually on hillsides and ridges with sandy to clay soils, but also on ultrabasic and limestone.

Uses
The wood is used for general construction. The bark is used in flavouring food, while Safrol, a scent of soaps is extracted from the wood. In Indonesia the flowers symbolize love and connection between the living and the dead. Traditionally, in the Kudus Regency on the island of Java, the flowers we scattered on tombs by family members. The tree is of special concern, as it is being harvested at a high rate to obtain safrole, a precursor to the pesticide synergist piperonyl butoxide, the flavorant and fragrance piperonal, and the psychoactive drug MDMA. Much of this illicit harvesting is happening in the Cardamom Mountains in Cambodia. The leaves are used as feed for the silkworm native to Hainan.
