Leaves essentially glabrous, 6-to 12 (generally 6-to 8)-foliolate; petiole short; leaflets obliquely ovate or ovate-elliptic, 3-5 cm. long, short-acuminate apically, obtuse or rounded basally, coriaceous, markedly reticulate, with a prominent midvein and many con-spicuous lateral veins, usually alternate except terminally on leaf; petiolules flat-tened, rugose when dry. Inflorescence of many small flowers, as described for the genus. Flowers apetalous; calyx-lobes 4, narrowly ovate to elliptic or lanceolate, about 3 mm. long, subhirsute within, glabrous without, spreading; stamens usually 10, 7-8 mm. long; filaments slender, glabrous; anthers versatile, oblong, almost 2 mm. long; ovary suborbicular, flattened, hirsute marginally; style arcuate, up to 5 mm. long, bearing a capitate stigma.
