Stems monocaulous to well branched, pachycaulous. Leaves alternate, petiolate, the bases clasping with connate and often ligulate stipules; blades palmately compound to bundle compound (rarely unifolioate or twice compound); leaflets linear to lanceolate, ovate, elliptical, obovate, or oblanceolate, membranaceous to coriaceous, entire to variously toothed or lobed, sessile or petiolulate. Inflorescences terminal or pseudolateral, erect or pendant, paniculate, racemose, or simple to compound umbellate, the ultimate units umbellules, capitula, racemules, or spicules; bracts present or absent; pedicels slender to stout; unarticulated. Calyx forming a low rim or with ca. 5 small teeth; petals (4 or)5(–7+), valvate, free or occasionally calyptrate; stamens typically isomerous with petals, but up to 250+ in 1–several whorls, thecae 2 or 4 per anther; carpels (2 or)5–20(–100+); ovary inferior to half-inferior, styles free to fully connate; the disc depressed to flat or nearly hemispherical. Fruits drupes, glabrous or pubescent, obloid to globose, ellipsoid, or ovoid, terete to laterally compressed, the endocarps crustaceous to boney. Endosperm uniform, rugose, or ruminate. 2n = 24, 48.
