Description: Andromonoecious treelets or small trees 2–6(–7) m tall. Leaves (8–)13–40(–50) cm long; leaflets 1 (the leaves thus unifoliolate), 3 or 5 (rarely 2 or 4), dark green or yellow green above, paler beneath, papyraceous to subcoriacecous, widely elliptic to oblate or reniform, occasionally somewhat ovate or obovate, flat or sometimes adaxially concave and shallowly scutellate, (5–)6–20(–24) × (5–)6–20(–26) cm, the apex rounded (rarely slightly emarginate), the margin subentire to coarsely crenulate or shallowly serrate (occasionally to subpalmately lobed), slightly thickened and often minutely revolute, the teeth 1-2 cm distant in larger leaflets and sometimes conspicuously spinulose, the base shallowly cordate or convex (rarely rounded-truncate); petiolules (0.5–)1.5–5 cm long; rachis articulated at petiolule bases (including in unifoliolate leaves); petiole (3–)5–20(–30) cm long, enlarged and clasping at the base, evidently alate for 1–5(–6) cm with membranous wings. Inflorescence terminal, erect, glabrous through-out, the scarious bractlets early caducous, the primary axis stout, often lenticellate, 30–80(–100) cm long, the secondary axes ca. 15–30, grouped in 2–4 verticils (occasionally opposite or irregularly scattered below), 15–50 cm long, tertiary axes (peduncles) ca. 7–30 per secondary axis, grouped in 4–6 often somewhat irregular verticils, each 2–18 mm long at maturity, with a terminal umbellule of (5–)8–25 hermaphroditic, protandrous flowers and functionally staminate flowers, and bearing 2–6 paired (or occasionally scattered to irregularly grouped), scarious, adaxially concave, deltate-triangular bractlets, each 0.5–1 mm long, the pedicels slender, 1.5–7 mm long. Calyx broadly cupuliform, 0.4–1.2 mm high, the rim undulate and irregularly 5–8-denticulate, hyaline. Corolla elliptic to subglobose in bud, the petals (4–)5–7(–9), spreading to recurved at anthesis, ovate-lanceolate, 1.6–2.5 mm long (somewhat smaller in staminate flowers). Stamens as many as petals, the filaments 0.5–1 mm long, the anthers cream white, 1.2–1.8 mm long. Ovary (2–)3–5-carpellate, obtriangular to broadly urniform, 0.5–1 mm high at anthesis; styles as many as carpels, free nearly to the base, 0.4–0.6 mm long and erect at anthesis, spreading and expanding slightly in fruit to 0.8 mm long. Mature fruit infrequently seen, subglobose to depressed-globose (somewhat triangular to quadrangular when 3- or 4-carpellate), 4–6 mm high, ribbed when dry.
