Small tree up to 10 m. tall or shrub; branchlets fulvous-tomentose to nearly glabrous. Leaves 3-foliolate; petiole up to 7 cm. long, nearly glabrous to densely pubescent; leaflets subequal or with the terminal one up to 11/2 times as long as the lateral ones; petiolules up to 12 mm. long in the terminal leaflet but rarely exceeding 2 mm. in the sometimes subsessile lateral ones; lamina of terminal leaflet up to 15 × 8 cm. (sometimes larger outside our area) but often much smaller (especially in Groups C and D, q.v.), obovate to elliptic, chartaceous to subcoriaceous, almost glabrous to pubescent above, almost glabrous to tomentose beneath, minutely glandular beneath and sometimes with tufts of hairs in the axils of the lateral nerves, apex acute or rounded and sometimes slightly acuminate, margin shallowly crenate-serrate or shallowly serrate or sometimes subentire, base cuneate to narrowly cuneate (rarely appreciably narrowed except in some possible hybrids); lateral nerves 6–9 pairs. Inflorescence 9–26 cm. long, branched, densely pubescent. Flowers white, cream, yellow or green, in few-flowered subsessile glomerules; pedicels up to 2 mm. long. Outer sepals 1·8 × 1·8 mm., subcircular, inner 1·5 × 1 mm., elliptic, all glabrous to pubescent. Petals 1·2 × 0·9 mm., spathulate. Stamens with filaments 1·5 mm. long; staminodes 0·5 mm. long in male flowers. Ovary 2-lobed; style 1·8 mm. long, 2-fid. Fruit red or orange turning red, 4–6 mm. in diam., subglobose in our area (sometimes ellipsoid elsewhere), sparsely pubescent to pubescent when young, glabrous to pubescent when mature, 1 coccus (rarely 2) developing.
