Sindora wallichii Benth.

Tree up to 24(-33) m high, 67 cm in diam. Stipules foliaceous, subintrapetiolar, falcate, up to 15 mm long, acuminate, rounded auriculate at base, reticulate and finely puberulous on both surfaces, tardily caducous. Leaves 3-or 4-jugate; petiole 1.2-2.5 cm and rachis 4.5-8.5 cm long, minutely puberulous, glabrescent, or sometimes glabrous in the upper half. Leaflets coriaceous, elliptic-ovate or elliptic-oblong, ovate-or obovate-oblong, 4-10.5 by 2.5-5 cm, upper pair usually the largest; apex acute, subacuminate, obtuse, the very tip slightly notched; base obtuse or rotund, often more or less unequally sided; upper surface brightly glossy and glabrous, sometimes puberulous in the lower half or very minutely puberulous all over; lower surface rather dull and glabrous or densely pubescent; petiolules very short or subsessile, up to c. 3 mm, puberulous, glabrescent, or glabrous. Inflorescences paniculate, up to 24 cm long, lateral branches zigzagging, rather short, up to c. 4.5 cm long, both rachis and branches densely puberulous; bracts triangular, wider than long, up to 4 mm long and 7 mm wide, puberulous on both surfaces; bracteoles oblong or lanceolate, c. 4.5 mm long, puberulous on both surfaces; pedicels almost absent or very short, up to 4 mm, puberulous. Calyx lobes lanceolate, up to 9.5 by 3 mm, outside puberulous and bearing some distinctly spiny outgrowths often in the upper half, inside glabrous. Petal elliptic or oblong-elliptic, c. 8 by 2-2.5 mm; outside woolly; glabrous inside. Stamens: united basal parts of the filaments very short; free filaments up to c. 10 mm, slightly hairy at the lower part; (fertile) anthers various in size, the 2 larger ones ovoid-ellipsoid, c. 3.5 mm long, the others smaller. Ovary sessile or shortly stiped, subrhomboid, c. 5 mm long, densely hairy, with many minute, spiny outgrowths, 2-4-ovuled; style up to c. 10 mm, recurvate, glabrous or sparsely hairy in the basal part; stigma terminal, small, capitate. Pods on a very short peduncle, suborbicular, broadly obovoid or ellipsoid, 6-10 by 4-6 cm, flattened, both surfaces covered with close, hard, straight spines (up to c. 5 mm); beak curvate, c. 8 mm long; 1-or 2-(or 3-)seeded. Seeds suborbicular, c. 2 cm in diam., on a larger aril (often broader than long).

Lowland forests, on non-inundated sandy or sometimes clayey soils, sometimes near mangrove swamps; usually found at elevations below 100 metres, but sometimes up to 300 metres.

Can be grown by seedlings.
