Shorea crassa P.S.Ashton

Medium-sized to large tree. Twig, panicle, bud, stipule (outside only; glabrescent within) and petiole densely shortly tomentose, with minute adpressed persistent hair tufts; leaf nervation beneath sparsely so. Twig to 5 by 2.5 mm ø apically, compressed, becoming terete and glabrous, sometimes narrowly evenly cracked; stipule scars c. 2 mm long, cuneate, pale, ascending. Bud to 6 mm long and broad, ovoid, compressed, subacute. Stipule to 8 by 4 mm, ovate, cupped, subacute, fugaceous. Leaves 10-18 by 5-10 cm, elliptic to ovate, pale cream to golden lepidote beneath; base equal or subequal, cuneate or narrowly obtuse, occasionally subcordate; acumen to 1 cm long; nerves 7-11 pairs, prominent, well spaced, at c. 40°-55°; tertiary nerves slender, sinuate, densely scalariform; midrib applanate at base, depressed towards apex, above; petiole 3.5-5 cm long, stout. Panicle to 13 cm long, terminal or axillary, terete or somewhat compressed, ribbed on drying, stout; regularly singly branched, branchlets to 4.5 cm long, bearing to 12 distichous flowers; bracteoles to 3 mm long, suborbicular, shortly pubescent, caducous. Flower bud to 15 by 3.5 mm, narrowly lanceolate. Calyx pubescent outside, glabrescent within; lobes broadly ovate, subacute; outer lobes slightly longer, more obtuse than inner. Petals cream, pink at base, linear, shortly pubescent, glabrescent within. Stamens 38-46; filaments broad at base; tapering, hispid; anthers narrowly oblong, cells tapering, sacs subequal or the outer slightly larger; appendage to connective prominent but always shorter than the anther, setose. Ovary ovoid, glabrous at base, otherwise tomentose; stylopodium longer than ovary, cylindrical, tomentose; style very short, glabrous. Fruit calyx sparsely puberulent towards apex, more densely so towards base; 3 longer lobes to 9 by 2.5 cm, broadly spatulate, coriaceous, obtuse, c. 8 mm broad above the c. 1.5 by 1.3 cm elliptic shallowly saccate thickened base; 2 shorter lobes to 7 by 0.7 cm, narrowly oblong, similar at base. Nut to 2.5 by 2 cm, ellipsoid, densely shortly cream tomentose; style remnant stout, tapering, to 8 mm.

Common on deep leached yellow sandy and sometimes clay soils, on low hills, terraces and occasionally dry sandstone ridges to 1000 m; mainly near the coast.
