Rinorea sclerocarpa


Growth apparently in flushes; Leaves mostly distichous. Stipules (3-)4-7(-10) mm long, not appressed, triangular, with a pale-hairy keel, more or less striate, their scars not conspicuous. Inflorescences in the axil of the 2-4 latest leaves, 2-5 cm long, often rich-flowered and sometimes quite densely, peduncle mostly near the base divided into 2-4 main axes, which after anthesis may long persist as partly empty stalks; Flowers pear-shaped, the corolla converging. Sepals subor-bicular, (2-)2½-3(-4) mm, fleshy, sparsely hairy. Petals 3½-4 mm long, sometimes the top slightly recurved, outside sparsely hairy towards the top. Fruits seldom more than 2 per inflorescence, subtended by the persistent sepals, before maturity mostly tapering to both ends, (0.9-)2.3-3 cm long, bluntly triangular with hollow sides (0.8-) 1.5-2 cm wide, dull dark-purplish, the valves eventually spreading, compressed and separating into two layers, the inner one cartilaginous and straw-coloured, the outer one leathery. Seeds 3-6, c. (5-)6-8 mm long, evenly dull brownish.

, had it under Alsodeia obtusa, our Rinorea bengalensis; , under Alsodeia javanica.
Alsodeia rugosa was described with a hairy ovary; in the buds available this was glabrous.
A CHR. SMITH specimen (BM), stated to be from Ceram, fl. II. 1802, must have been wrongly labelled.
