Description: Andromonoecious trees or shrubs c. 4–10 m tall, branched to well branched. Leaves palmately compound, 10.5–25.5(–37) cm long (incl. petiole); leaflets (1 or)3–5, dark to medium green above, pale green beneath, dull to shiny (rarely glaucous), coriaceous, obovate (to elliptic), (1.5–)2.5–14.5 × 1.5–7 cm (the lateral ones generally reduced), glabrous, smooth above, primary vein yellow green, primary and secondary veins slightly raised above, conspicuously raised beneath, secondary veins c. 5-20 per side, tertiary veins faint, ± parallel to secondary veins but branching toward margin, the base attenuate (but often appearing to form a petiolule to 15 mm long), the margin entire, sometimes slightly undulate or irregularly crenate, minutely to strongly revolute, the apex obtuse, acute, round, retuse and sometimes cuspidate or mucronate; petiole 4–15(–22) cm long, 1.5–3 mm diam., the base clasping, neither inflated nor lenticellate, the ligulate stipule 3–8 mm long, forming a low, semi-circular crown. Inflorescence terminal, a compound umbel, obdeltoid (to obconical), with 3(or 4) orders of branching, glabrous, often subtended by cataphylls, the bracts caducous, triangular, 1.5–4 mm long, the primary axis erect, 0.4–4.5 cm long, the secondary axes 3 to 10, forming an umbel, occasionally with 1 borne below the terminal cluster, each 1.5–10.5 cm long, terminating in an umbellule of (0–)3–12 protandrous, hermaphroditic flowers and 3–12 third order axes, each 1–8 cm long, with 6–14(–24) staminate flowers, pedicels of the hermaphroditic flowers (<1–)4–17 mm long, 0.5–2 mm diam., those of the staminate flowers 1–5 mm long, 0.5–1 mm diam., subtended by caducous, triangular to narrowly triangular bracts, each 0.6–1 mm long. Calyx rim undulate, fringed, with 5 minute, apiculate teeth hermaphroditic in flowers, cupuliform in staminate flowers, c. 0.25–0.5 mm high, 1.5–5 mm in diam. Corolla conical to ellipsoid in bud, the petals 5, spreading to reflexed at anthesis, yellow-green, triangular to narrowly triangular, 1.2–2 mm long, 1.2–2 mm wide. Stamens 5, the filaments 1.1–2 mm long, the anthers cream white, 1.2–1.5 mm long, with 2 thecae. Ovary (3- to)5-carpellate, cylindrical, ovoid to ellipsoid at anthesis (vestigial in staminate flowers), 5–9 mm high, disc conical, c. 2–4 mm diam., styles (3–)5, 1.2–2 mm long, united for 2/3–3/4 of their length, basal portion conical, free arms 0.5–2 mm, erect to somewhat divergent at anthesis, recurved in fruit. Mature fruit terete to 3–5-angled, dark green, turning purple, ovoid to narrowly ovoid or ellipsoid (to cylindrical), 8–14 mm high, 3.5–10(–14) mm wide, strongly ribbed when dry, the base rounded to somewhat truncate, the disc yellow-green to medium green, turning purple.
