Indumentum on young parts dense, straw-coloured. Flowering twigs terete, 4-5 mm in diam., grooved, tomentose. Leaves 4-6-jugate; petiole 5-2.5 cm long, flattened above, rounded below; rachis 12-19 cm long, flattened above, rounded below, usually towards the apex terete, striate; petiole and rachis tomentose; petiolules (2-)5-8 mm long, grooved above, tomentose. Leaflets alternate, elliptic to obovate, slightly asymmetric, 8-15 by 3-5.5 cm, index 2.1-3.2, dark, glossy green above, chartaceous, above almost glabrous, midrib and nerves puberulous at least in basal part of leaflet, below almost glabrous to very thinly puberulous, midrib and nerves more or less puberulous; base cuneate; apex acuminate, acumen 4-28 mm, rounded; margin entire or obscurely crenate towards the apex; midrib above slightly sunken, nerves 11-19 per side, 6-13 mm apart, angle to midrib (50-)70-80°; domatia small, pocket-like to more or less dome-shaped. Inflorescences axillary, 13-17 cm long, with short or long branches, laxly flowered; cymules 1-flowered; bracts and bracteoles lanceolate to deltoid, 0.6-2.5 by 0.4-1 mm, not persisting, outside appressed-hairy, inside glabrous; pedicels c. 2 mm long, articulated at the base. Flower buds globular, 4 by 4 mm, flowers only known in bud and from under the young fruits. Sepals persisting, more or less orbicular, concave, with a narrow to wide scarious rim, outside appressed-hairy except rim, margin ciliate in basal part, and with sessile glands, inside shortly appressed-hairy in basal part. Petals white, angular, 3-dentate at apex, appressed-hairy at the base on both sides; scales 2, not crested, woolly. Disc glabrous or with 5 tufts of hairs. Stamens 10, filaments and anthers hairy. Pistillode 3-celled, hairy. Young fruits yellowish or pale orange, more or less globular, wall 2.4-3.6 mm thick, outside rugose, velutinous, inside glabrous.
