Description

Key Characters:

Growth Form: Trees 3–4.5 m tall; secretory canals present in most parts.

Stems:

Roots:

Leaves: Leaves compound (palmate). Opposite. Leaflets 3 (occasionally 5 on juvenile leaves), elliptic to ovate, 5–12 cm long and less than 1⁄2 as wide. Apex rounded-acute to acuminate. Base narrowly cuneate to attenuate. Blades subcoriaceous. midvein, margins, petiolule, and petiole usually tinged purple, petiolule often laterally compressed. Margins entire. Veins strongly sunken on upper surface in dried material (weakly so in juvenile leaves). Petioles base often broad and sheathing the stem. Petioles 3–7(–10 in juvenile leaves) cm long, petiolules 0.5–1.5 cm long, subterete. Stipules absent.

Flowers: Flowers in terminal, erect, oppositely branched panicles of umbellules. Inflorescences up to 10 cm long. Bracts minute, subconnate, persistent, forming an involucel below the umbellules and pseudocalyx below each flower; pedicels 3–6 mm long. Flowers bisexual (perfect) and functionally staminate (the plants andromonoecious). Calyx of 5 short, basally connate teeth. Corolla of 5(6) petals, buds dark purple, mature petals purple externally, greenish within, valvate, caducous, triangular to ovate or oblong, apex inflexed. Stamens usually as many as and alternate with the petals, sometimes numerous, distinct, inserted at the edge of the epigynous nectary disk; 5, pale yellow, spreading. Ovary inferior, (4)5-carpellate, carpels connate (rarely pseudomonomerous), with as many cells; ovules pendulous, 2 per cell, 1 abortive; styles (4)5, 1–1.5 mm long, connate 1⁄2–¾ their length into a conical-cylindrical stylopodium, the distinct arms divergent to spreading.

Fruit: Drupes green; ripening dark purple; exocarp fleshy; globose; or laterally compressed and orbicular or oblate to ovoid or obovoid; 3–7.5 mm long; pyrenes cartilaginous; laterally compressed; as many as styles.
