Species Description - Tree; young shoots densely golden long-hispid, becoming glabrous, dark brown, smooth, lenticellate. Leaves spaced or loosely clustered, spirally arranged, 12.5-25.7 × 3.8-7.8 cm, oblanceolate, apex narrowly attenuate to long acuminate, base long tapering from above halfway, finally acute or narrowly cuneate, chartaceous, glabrous, or with residual hispid indumentum along the lower midrib; venation eucamptodromous-brochidodromous, sometimes with thin marginal vein, midrib raised on the upper surface, secondary veins, 12-20 pairs, slightly convergent and arcuate, slightly impressed on the upper surface, strongly raised below; intersecondaries small or absent; tertiaries few, widely spaced, oblique, quaternary reticulum present. Petiole 0.5-1 cm long, slightly channelled, densely long-hispid, soon glabrous. Fascicles 2-3-flowered, mostly below the leaves at defoliated nodes. Pedicel 2-3 mm long, densely hispid, slightly reflexed. Flowers unisexual (plants dioecious (?)). Male or bisexual flowers not seen. Sepals five, 1.5-2 mm long, broadly lanceolate, apex obtuse, densely long-hispid outside, glabrous within. Corolla narrowly cyathiform, ca. 1.5 mm long, tube ca. 0.4 mm long, lobes five, ca. 1.1 mm long, ovate, apex obtuse, glabrous. Stamens and staminodes absent. Disk absent. Ovary conical, tapering imperceptibly with the style and filling the corolla, bilocular, densely strigose; style ca. 0.7 mm long, densely strigose; style-head simple. Fruit 2.5-3 cm long, ellipsoid or obovoid, apex rounded, base acute to rounded, smooth, densely hispid, style persistent. Seed solitary, (immature) laterally compressed, testa smooth, free from pericarp; scar narrowly adaxial, ca. 1.5 mm wide; embryo with plano-convex, free cotyledons, radicle extending to the surface; endosperm absent. Field characters. Tree to 10 m high with white latex. Flowering Jun and Jul, fruit Jun.
