Description: Andromonoecious shrubs and trees (1.5)2.5–5(–6) m tall, monocaulous or sparsely branched. Leaves palmately compound, 36–75 cm long (incl. petiole); leaflets 8–13, medium to dark green above, lighter beneath, shiny to dull above, papyraceous to subcoriaceous, narrowly elliptic, narrowly elliptic, obovate or narrowly obovate, 10.5–22(–30) × 3–7(–9) cm (leaflets 3 in juvenile foliage, linear, 9–15 × 0.4–0.6 cm), glabrous, the primary vein yellow green, scarcely to prominently raised above, evidently raised beneath, secondary veins 28–52(–70) per side, raised above, less evidently so beneath, tertiary veins evident on both surfaces, cuneate to decurrent, the margins entire, coarsely undulate, minutely revolute, the apex rounded, sometimes retuse or acute to acuminate; petiolules 2.5–5(–6) cm long (leaflets in juvenile foliage sessile); petiole 21–47 cm long, 3–7 mm diam., distal portion sometimes with a white, waxy pruinose coating , the base clasping, occasionally sparsely pustular lenticellate, the ligulate stipule forming a collar ca. 5 mm high. Inflorescence terminal, paniculate-umbellate, hemispherical to ellipsoid, with 3 or 4 orders of branching, glabrous, light to medium green, almost always covered with a white, waxy pruinose coating in vivo and usually in seco, cataphylls resembling leaf bases, often persistent, inflorescence bracts triangular, caducous, ca, 3.5 mm long, the primary axis erect, 3.5–6 cm long, the secondary axes 4–7, 1 or 2 borne laterally along the primary axis, the others forming a terminal, umbellate cluster, each ca. 6.5–47 cm long, tertiary axes ca. (4–)7–14 per secondary axis, ca. 0–4 arranged singly and/or pairs and/or a pseudo-whorl, the others in a terminal, umbellate cluster, each ca. (1–)2.5–12.5 cm long, bearing a terminal umbellule of ca. 8–15 protandrous, hermaphroditic flowers and sometimes 1–4 lateral umbellules of ca. 5–14 staminate flowers or mixed with some hermaphroditic flowers, pedicels of the hermaphroditic flowers 8–25 mm long at anthesis, ca. 0.5–1 mm in diam., those of the staminate flowers ca. 3–4 mm long, ca. 0.5 mm in diam., expanding to (5–)8–25 mm long in fruit, subtended by triangular, caducous bracts 1–1.5 mm long. Calyx a low rim or collar, sometimes undulate, ca. 2–3 mm wide at anthesis, the rim 0.1–0.3 mm high, often minutely apiculate (smaller in staminate flowers). Corolla spherical in young but, ellipsoid prior to anthesis, the petals 5, triangular, ca. 2–3 mm long at anthesis. Stamens 5, the filaments ca. 1–2 mm long, the anthers 1–2 mm long, with 4 thecae. Ovary 5-carpellate, obovoid to subglobose (vestigial in staminate flowers), disc flattened to depressed, ca. 2–3 mm diam. in hermaphroditic flowers (smaller in staminate flowers), styles 5, ca. 0.5–0.8 long in hermaphroditic flowers (vestigial and undivided in staminate flowers), united for ca. 1/2–2/3 of their length, the free arms 0.2–0.4 mm long, ascending at receptivity. Mature fruit terete, ellipsoid to ovoid, sometimes narrowly so, 4–8 mm high, 2.5–5 mm wide, ribbed when dry, the base rounded.
