Trees. Leaves simple, alternate, entire, subentire or serrate, pinnately veined, often With tufts of hairs in axils of veins beneath; petioles often swollen and geniculate; stipules Small, linear, rarely large, foliaceous, caducous. Flowers axillary, solitary or fascicled, rarely cymes or racemes. Flowers pale white, often fragrant. Sepals 4(- 5), free or connate at base, valvate or imbricate. Petals 4(- 5), distinct or sepaloid or absent, free, rarely connate at base, entire or variously laciniate. Stamens numerous, free; filaments long or short, hairy; anthers linear or oblong, hairy, awned or not, 2-loculed, dehiscing by transverse slits at apex. Disc thick, broad, flat or cushion-shaped. Ovary superior, sessile, tomentose, 2 - 7-loculed, with numeous ovules in each locule; styles short or long, subulate, often twisted, hairy at base; stigmas entire. Fruits 2 - 5(- 7)-valved woody capsules; valves smooth or covered with bristles or spines; spines simple, broad-based, glabrous or hairy, deciduous or persistent; locules 2 - 4-seeded, rarely 1-seeded. Seeds ovoid, usually artillate, testa bony, shining.

Literature. COODE, M.J.E. (1983). A conspectus of sloanea (Elaeocarpaceae) in the Old world. Kew., Bull. 38: 347 - 427. SMITH, C.E. (1954). The New World of species of Sloanea (Elaeocarpaceae). Contr. Gray Herb. 175: 1 - 114. TIREL, C. (1980). Nauvelles Caledonia. Adansonia 2, 20: 91 - 106.

Notes. Hutchison in his The Genera of flowering plants, vol. 2(1967) treats Sloanea L. (1753) to be distinct from Echinocarpus Blume(1825) on the basis of sepals being imbricate in 2 series in Echinocarpus and valvate in 1 series in Sloanea. According to him, the species distributed in Old World i.e. Eastern and S.E. Asia, Australia etc. belong to Echinocarpus and those distributed in the New World belong to Sloanea. and this was followed by Santapau & Henry (Dictionary of the flowering plants in India 1973). However, Airy shaw (in J.C. Willis, A Dictionary of the flowering plants and ferns, 1973) treats both as congeneric, merging Echinocarpus under Sloanea and this view is followed in this flora.
