Shorea laevis Ridl.

Vast, prominently buttressed tree. All vegetative parts epilose. Twig c. 1 mm ø apically, much branched, slender, terete, smooth; stipule scars small, obscure. Bud c. 3.5 by 1.5 mm, narrowly ovoid. Stipule to 8 by 2 mm, narrowly lanceolate, acute, fugaceous. Leaves 6.5-10 by 2.5-4 cm, narrowly ovate-lanceo-late; falcate, thinly coriaceous, cream lepidote beneath in mature trees; base subequal, broadly cuneate; acumen to 2 cm long, slender; nerves 11-14 pairs, slender, coriaceous, dense, curved, at c. 50°-60°, unraised on either surface as also the midrib; tertiary nerves slender, densely scalariform, diagonal to nerves; petiole 1-1.5 cm long, slender, geniculate. Panicle to 12 cm long, terminal or axillary, slender, terete, shortly persistently pale cream grey pubescent, ± glabrescent; singly or doubly branched, branchlets to 3 cm long, bearing to 9 distichous flowers; bracteoles to 2 mm long, linear, pubescent, fugaceous. Flower bud to 2 mm long, globose. Calyx shortly pale cream-brown tomentose outside, glabrous within; 3 outer lobes ovate-deltoid, subacute; 2 inner lobes smaller, suborbicular. Petals small, oblong, shortly pubescent on parts exposed in bud. Stamens c. 50; filaments slender, tapering, sparsely barbate towards the apex; anther oblong, the longer, outer, sacs barbate at base and apex; appendage to connective small, barbate. Ovary and stylopodium small, conical, densely buff tomentose, crowned by a short glabrous style. Fruit calyx shortly buff pubescent on both surface; 3 longer lobes to 6.5 by 1 cm, oblong, chartaceous, slightly broader at the obtuse apex, un tapering but saccate and adpressed to the nut at the base; 2 shorter lobes to 4 by 0.5 cm, subacute, otherwise similar. Nut to 1.5 by 0.9 cm, ovoid, shortly densely evenly buff pubescent; style remnant to 4 mm long, tapering, frequently bent over.

An emergent tree, mostly on hillsides and ridges, but also on alluvial sites, in undisturbed mixed dipterocarp forests at elevations up to 600 metres. When found in secondary forests, it is usually present as a pre-disturbance remnant tree.

Can be grown by seedlings. Seeds needs soaking.
