Description:
Dioecious treelets (1–) 2–3 (–4) m tall, monocaulous to sparsely-branched. Leaves once-pinnate, (25–) 30–40 (–64) cm long; leaflets (5–) 9–15, lamina pale green, dull above, paler below, membranous to coriaceous, ovate to somewhat oblong-elliptic, (5–) 7–11 (–14) × (2–) 3–6 (–8) cm, the apex acuminate (to acute), the margin crenate-serrate, thickened but not revolute, the base asymmetric, acute to truncate or rounded; petiolules (3–) 10–15 (–20) mm long; rachis usually articulated at insertion of leaflets, glabrous; petiole (8–) 10–14 (–22) cm long, , (1–) 2–4 (–6) mm diam., glabrous, without an alate base. Inflorescence a panicle of racemules, terminal, erect, pyrimidal to oblong, the axes with very short puberulence (especially on the ultimate axes); the bractlets caducous, not seen but leaving a scar of 1–1.5 mm, the primary axis (8.5–) 9–26.5 (–51.5) cm long; the secondary axes (7–) 8–10 (–12), scattered, (1–) 9–25 (–33) cm long (the upper ones sometimes reduced); the tertiary axes 7–25 per secondary axis in pistillate inflorescences, 24–34 per secondary axis in staminate inflorescences, scattered along its length (but often in clusters of 2–4), 5–40 mm long, with 1–3 (–6) terminal flowers plus 5–13 lateral flowers in pistillate inflorescences and 2–5 terminal flowers plus 12–31 lateral flowers in staminate inflorescences, each flower subtended by a caducous, linear to narrowly triangular bractlet 1–1.5 mm long; flowers very nearly sessile or pedicels ranging to 1 mm long in in pistillate inflorescences and 0.3 mm long in staminate inflorescences, 0.2–1 mm diam., articulated below the ovary. Calyx a very low collar (sometimes scarecely evident), 0–0.2 mm tall, rim entire or with ca. 4 minute apiculate or shallowly triangular teeth. Corolla in bud oblong to occasionally hemispheric; the petals 4, in pistillate flowers spreading to reflexed, narrowly triangular, 1.2–2 × 1.0 mm, in staminate flowers strongly recurved at anthesis, narrowly triangular, 1.2–2 × 1–1.5 mm. Stamens ascending to spreading at anthesis (present in both staminate and pistillate flowers), filaments <1.0 mm long, anthers 1.1–1.8 mm long. Ovary 2-carpellate, elliptic to obovate, ca. 5 mm tall at anthesis in pistillate flowers; ovary of staminate flowers vestigial, obconic; styles 2, free (or fused only at the very base), 1–2 mm long with the arms erect to ascending when receptive and spreading to reflexed in fruit (styles vestigial in staminate flowers, <0.5 mm long). Mature fruit laterally compressed, turning dark purple, oblong-elliptic to broadly ovate to somewhat obovate, 3.8–5.5 × 4.0–5.0 mm, glabrous, the base rounded to slightly cordate, the ribs weakly developed when dry.
