Characteristics

Trees 3.5-25 m high, dbh 10-35 cm, bole flanged all the way up; bark pale grey or greenish to dark brown, smooth except for longitudinal cracks, underbark red, inner bark straw yellow to brown; wood straw or white. Flowering twigs terete, 2-6(-12) mm in diam., dark brown, striate to grooved, tomentose, glabrescent, exceptionally (Hartley 13129, de Vogel 3494) villose. Leaves (3-)4-6(-8)-jugate; petiole (3—)7—13 cm long, flattened above, rounded below, rarely towards the apex terete; rachis 9-26(-38) cm long, flattened above, rounded below, or terete, striate, more or less tomentose; petiolules 2-10 mm long, grooved above, tomentose. Leaflets alternate to opposite, (narrowly) obovate, rarely elliptic, slightly asymmetric, 7-22 by 2.5-8 cm, index 1.8-4, redbrown when young, later on glossy pale to dark green above, pale to medium green below, chartaceous, above and below almost glabrous, midrib and nerves almost glabrous to shortly appressed-hairy; base cuneate to rounded; apex acuminate, acumen 1-20 mm long, acute to rounded; margin (obtusely) dentate in upper part, rarely entire; midrib above slightly sunken to somewhat prominent, nerves (9-) 10-19 per side, some of the upper ones ending in a tooth, 8-22 mm apart, angle to midrib (45-)55-80°; domatia small, pocket-like. Inflorescences axillary, 5-20(-34.5) cm long, with long or short, patent branches, tomentose, glabrescent, laxly flowered; cymules dichasial, several-flowered; bracts and bracteoles ovate to triangular, 0.6-5 by 0.4-2 mm, not persisting, outside appressed-hairy, inside glabrous or with some hairs at the base; pedicels 0.6-3.6 mm, articulated up to ⅔ above the base. Flower buds obovate to globular, 1.4-2.6 by 1-2.6 mm. Sepals white to brown, persisting, outside appressed-hairy except rim, margin ciliate and with glands, inside appressed-hairy, outer elliptic to triangular, 1-2.9 by 0.8-2.2 mm, scarious rim narrow, inner elliptic to orbicular, 1.6-3.5 by 0.8-2.9 mm, scarious rim wide, irregularly dentate at apex. Petals cream to pink, elliptic to obovate, 0.8-2.9 by 0.5-2.2 mm, glabrous or appressed-hairy in basal part on both sides, margin ciliate, sometimes (Schlechter 14436) with an apical tuft of hairs; scales 2, not crested, 0.6-1.3 mm long, long-woolly. Disc glabrous. Stamens 8, exserted; filaments pink, 1.4-2.6 mm long, patently hairy except apical part; anthers yellow, 0.8-2.6 mm long, glabrous, rarely hairy (Conn & Kairo 454, NGF 49156). Ovary 3-celled; style 2.3 mm long; stigma sometimes orange, 1.1 mm long, 3-lined; pistillode 0.4-1.3 by 0.4-1.3 mm, 3-celled, hairy. Fruits yellow to reddish brown, globular, 9-15 by 10-15 mm; wall 0.4-1.1 mm thick, outside rugose, villose, inside villose (see note 2). Seeds 9-10 by 6-8 mm, basal-ly attached, testa shiny black; arillode pale orange, covering most of the seed, lacerate; cotyledons collateral.
