Shorea inappendiculata Burck

Large buttressed tree with flaky bark. Twigs, buds, stipules, petioles, midrib above and panicles densely persistently scabrid rufous pubescent, leaf nervation beneath sparsely so (denser, longer in young trees); leaf undersurface frequently +-densely silvery lepidote. Twig 2-4 mm ø apically, blackish, prominently ribbed or compressed at first; stipule scars pale, horizontal. Bud to 6 by 4 mm, ovoid, conical; stipules to 10 by 4 mm, broadly lanceolate, acute. Leaves (7-) 10-16 by (2-)3-8 cm (to 30 by 15 cm in young trees), oblong-elliptic, coriaceous; base ± unequal, obtuse or cordate; apex shortly acuminate to obtuse; nerves 13-24 pairs, prominent beneath, ± distinctly depressed above with the lamina bullate between; tertiary nerves densely scalariform, slightly elevated beneath; midrib prominent beneath, depressed above; petiole 15-30 mm long, ± stout. Panicle to 10 cm long, axillary, ribbed when dry, rather unevenly persistently buff pubescent; singly branched, branchlets to 2 cm long, bearing to 7 secund flowers; bracteoles to 3 by 2 mm, elliptic, obtuse, shortly evenly pubescent, fugaceous. Flower bud to 7 by 3 mm, fusiform. Calyx lobes ovate, densely pubescent on parts exposed in buds, inner sepals fimbriate; 3 outer sepals subacute, larger than the 2 acuminate inner sepals. Petals linear, densely pubescent on parts exposed in bud. Stamens 28-34; filaments setose distally abaxially, compressed, tapering; anthers narrowly oblong-elliptic, sparsely setose distally, the 2 outer sacs larger than the 2 inner; appendage to connective as long as anthers on outer stamens, shorter on inner, with a few terminal setae. Ovary and stylopodium ovoid, densely pubescent, tapering into the short glabrous style. Fruit pedicel to 4 by 3 mm, broadening into the receptacle; fruit calyx glabrescent; 3 longer lobes to 13 by 3 cm, broadly spatulate, obtuse, c. 8 mm broad above to 15 by 12 mm ovate saccate thickened base; 2 shorter lobes to 10 by 0.9 cm, lorate, subacute, similar at base; nut to 33 by 16 mm, ovoid, prominently apiculate.

A canopy to emergent tree in lowland mixed dipterocarp forest on coastal hills and immediately behind the peat swamps; it usually grows on well-structured clay soils at elevations up to 400 metres.

Can be grown by seedlings. Seeds needs soaking.
