Description: Dioecious trees 1–4 (–8) m tall, monocaulous or sparsely branched. Leaves once-pinnate, 11–48 cm long; leaflets 7–11, lamina drying light to dark green, paler below, coriaceous, lanceolate, elliptical, narrowly or broadly ovate, or obovate 5.5–10.5 × (2.5–) 3.5–7.5 (–9) cm, the apex rounded to acute to acuminate, the margin undulate or crenate with 3–several rounded teeth (rarely sharply serrate), slightly thickened and occasionally minutely revolute, the base strongly asymmetric, truncate to rounded to cuneate; petiolules 6–10 mm long; rachis articulated at insertion of leaflets, glabrous; petiole 5.5–13 cm long, 3–5 mm diam., glabrous, base not alate (or only minutely so). Inflorescence a panicle of umbellules or subcapitula (pistillate individuals) or racemules (staminate individuals), terminal, erect, rounded or slightly oblong, the axes glabrous to puberulent throughout; the bractlets caducous, ovate with an acuminate tip, conduplicate, 4–7 mm long; the primary axis 5–14 cm long; the secondary axes 3–10, scattered, 3.5–7.5 cm long; the tertiary axes 4–14 per secondary axis, scattered along its length (typically terminated by an umbel of 4–6 tertiary axes), 10–35 mm long, each with a terminal umbellule or subcapitula of 4–5 pedicellate or subsessile flowers subtended by two ovate, acuminate , conduplicate bractlets 4–7 mm long; pedicels <0.5–1 (rarely 3–4) mm long, articulated below the ovary. Calyx collar-like, 1–1.2 mm tall, rim with ca. 4 triangular teeth. Corolla in bud narrowly pyramidal; the petals 4 [presentation of petals at anthesis not seen], narrowly triangular, 2 × 1.2–1.5 mm in pistillate flowers, 2.5–3 × 2–3 mm in staminate flowers. Stamens at anthesis not seen. Ovary 2-carpellate, elliptic to obovate/obtrapezoidal, 6–8 mm tall at anthesis in pistillate flowers; ovary of staminate flowers vestigial, obconic; styles 2, free to the base, 1.5–2.5 mm long with the free arms ascending when receptive and recurved in fruit. Mature fruit strongly compressed laterally, drying reddish, reddish-tan, to black, circular to elliptic to ovate or obovate/obtrapezoidal, (6–) 8–10 × (5–) 6–7 mm, glabrous, the base rounded to slightly cordate, the ribs well developed when dry.
