Description:
Dioecious shrubs to trees 1–4 (–20) m tall, sparsely- to well-branched. Leaves once-pinnate, (6–) 10–53 cm long; leaflets 3–9 (–11), lamina medium green, dull (more rarely shiny or glaucous) above, paler below, coriaceous, narrowly to broadly elliptical, ovate or obovate, 2.5–9 (–14) × (0.7–) 1.5–5.0 (–10) cm, the apex acute to acuminate or rounded to emarginate, the margin entire, to shallowly dentate or crenate, to deeply serrate, thickened and minutely to strongly revolute, the base acute to cuneate, sometimes asymmetrical (rarely rounded or obtuse); petiolules (1–) 3–10 (–20) mm long; rachis articulated at insertion of leaflets, glabrous; petiole (2.5–) 4–13 (–23) cm long, 1–5 mm diam., glabrous, without an alate base. Inflorescence a panicle of umbellules, terminal, erect, pyramidal to oblong or rounded, the axes glabrous (or less commonly puberulent, especially toward the ultimate axes); the bractlets often persistent, very narrowly triangular, 1–10 mm long; the primary axis (3.5–) 5–24 cm long; the secondary axes 6–17 (–23), scattered but often in clusters of two or three, 3–17 (–25) cm long; the tertiary axes (2–) 4–17 (to 36 in staminate inflorescences) per secondary axis, 3–30 mm long; scattered but often in clusters of two or three, terminating in umbellules of 3–7 flowers (and rarely 1 subtending lateral flower) in pistillate inflorescences, and (2–) 5–14 (–20) flowers (and 0–6 subtending lateral flowers) in staminate inflorescences; flowers and often tertiary axes subtended by typically persistent, very narrowly triangular bractlets 0.5–1 mm long; pedicels (0.5–) 1–4 mm long, 0.2–0.5 mm diam. Calyx a low collar or obsolete, (0–) 0.2–0.7 mm tall, rim with minute apiculate or shallowly-triangular teeth. Corolla in bud oblong to long-conical; the petals 5, ascending to spreading or recurved at anthesis, narrowly triangular, ca. 1.0 × 0.5 mm in pistillate flowers, 2.0–2.5 × 1.0–1.2 mm in staminate flowers. Stamens of staminate flowers ascending to spreading at anthesis, filaments 0.7–1.0 mm long, anthers1.0–1.5 mm long; stamens lacking in pistillate flowers. Ovary 2-carpellate, elliptic, 2–4 mm tall at anthesis in pistillate flowers; ovary of staminate flowers vestigial, obconic; styles 2, fused basally to half their length, 0.7–1.0 (–1.2) mm long, erect to ascending when receptive and spreading to strongly recurved in fruit. Mature fruit laterally compressed, turning purple, orbicular to oblate or elliptic, or slightly ovate or obovate, 3.0–6.5 × 3.5–6.0 mm, glabrous, the base rounded (rarely acute or slightly cordate), the ribs weakly to strongly developed when dry.
