Description:
Andromonoecious trees c. 2–4 m tall, monocaulous or sparsely branched. Leaves palmately compound, 15–33 cm long (incl. petiole); leaflets (3 or)5–7(–9), medium to dark green above, pale green beneath, shiny to dull or glaucous, strongly coriaceous, elliptic to obovate, 3–17 × 1.2–6 cm (the lateral ones generally reduced), glabrous, smooth above, primary vein often tinged brownish-purple to pale orange-yellow or reddish-orange, canaliculate above, raised beneath, secondary veins prominent and raised above, raised beneath, translucent, c. 20–30 per side, tertiary veins weakly raised, the base cuneate, the margin entire, very strongly revolute, sometimes tinged pale yellow-orange, the apex round or retuse; petiolule 0.8–4.5 mm long; petiole (3.5–)6.5–15 cm long, 5–8 mm diam., the base clasping, neither inflated nor lenticillate, the ligulate stipule forming a low, semi-circular crown. Inflorescence terminal, a compound umbel, hemispheric, with 3 orders of branching, glabrous, the bracts caducous, broadly triangular, 1 mm long, the primary axis erect, 1.2–7 cm long, the secondary axes 4–11, forming an umbel, each 6–14 cm long, terminating in an umbellule of 7–10 protandrous, hermaphroditic flowers and up to c. 10 staminate flowers, plus c. 5–8 third order axes, each 3–5 cm long, with 7–11 staminate flowers, pedicels of the hermaphroditic flowers 10–15 mm long, 1 mm diam., those of the staminate flowers 6–8 mm long, 0.5 mm diam., subtended by caducous, triangular bracts, each 0.5 mm long. Calyx rim craterform, wider than the ovary, with 5 broadly triangular lobes, each bearing an apiculate tooth, c. 0.5–0.7 mm high, 4–4.5 mm in diam. Corolla conical in bud (open flowers not known), the petals 5, narrowly triangular, 3 mm long, 2 mm wide, cream white. Stamens 5, the filaments 1 mm long in bud, the anthers cream white, 1.5 mm long, with 2 thecae. Ovary 5-carpellate, ellipsoid at anthesis (vestigial in staminate flowers), 5–7 mm high, disc conical to short-columnar, 2–3 mm diam., styles 5, 1.2–2 mm long, united for 1/2–2/3 of their length, free arms 0.7–1 mm, ascending at anthesis, recurved in fruit. Mature fruit terete to 5-angled, medium with darker vertical lines, turning purple, narrowly ovoid to ovoid (to nearly globose), 8–17 mm high, 6–9 mm wide, strongly ribbed when dry, the base rounded to truncate, the disc yellow orange, turning purple.
