Description: >Dioecious shrubs to small trees 1.5–3.5 (–5) m tall, sparsely to moderately branched crown. Leaves unifoliolate, 6–20 cm long; leaflets 1, lamina medium to olive green, occasionally glaucous or shiny above, paler below, (sub-) coriaceous, broadly ovate to elliptic, 3.3–11.5 × 2.0–8.0 cm, the apex acute to short-acuminate to emarginate, the margin entire, thickened and rarely minutely revolute, the base acute to rounded to obtuse; petiolules marked by a distinct articulation 0–12 mm below the single leaflet balde; petiole (2.5–) 5–8.5 cm long, 1.5–3.0 mm diam., glabrous, without an alate base. Inflorescence a panicle of umbellules, terminal, erect, pyramidal (to obconic), the axes puberulent; the bractlets triangular to spathulate to broadly ovate, 5–30 mm long; the primary axis 5–13 cm long; the secondary axes (3–) 6–13, scattered, (2–) 4–9 cm long (the upper ones reduced); the tertiary axes 7–20 per secondary axis, scattered along its length, (2–) 4–9 (–12) mm long, each with a terminal (often irregular) umbellule of (5–) 6–7 (–11) flowers (often including an additional, fourth-ranked umbellule in pistillate inflorescences, or subtended by a 2-flowered umbellule in staminate inflorescences), flowers subtended by a caducous linear, conduplicate bractlet 2–3 mm long; pedicels 1.5–5 mm long, 0.2¬0.8 mm diam., articulated below the ovary. Calyx collar-like, <0.7 mm tall, rim with ca. 5 minute apiculate or shallowly triangular teeth. Corolla in bud oblong to (hemi-) spheric; the petals 5, in pistillate flowers spreading to reflexed at anthesis, triangular, ca. 1.0 × 0.8 mm, in staminate flowers strongly recurved at anthesis, narrowly triangular, ca. 2.0 × 1.0 mm. Stamens ascending to spreading at anthesis (not seen in pistillate flowers), filaments ca. 1.0 mm long, anthers <1.0 mm long. Ovary 2-carpellate, circular to elliptic to obovate, 3–4 mm tall at anthesis in pistillate flowers; ovary of staminate flowers vestigial, obconic; styles 2, free to fused at the very base (no more than 1/5 their length), 1–1.5 mm long with the free 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, pale- or yellow-green, turning purple, circular to widely ovate or widely obovate, 3–5 × 3.5–4.5 mm, glabrous, the base rounded to slighlty cordate, the ribs weakly developed when dry.
