Characteristics

Tree, up to 15 m tall, sometimes a shrub. Branchlets subterete or obscurely 4-angular. Leaves chartaceous, ovate to obovate-oblong, rarely suborbicular, 3-8 by 1.5-5.5 cm; base cuneate; apex obtuse, acute, rarely acuminate, very rarely retuse; margin entire, sometimes slightly recurved; nerves about 6 pairs; petiole 2-5 mm. Cymes 1(-2), axillary, sometimes also terminal, rarely on the internodes in opposite pairs, few-flowered, sometimes 1-flowered. Peduncle very short, 2-3 mm. Pedicel 1-2 mm, articulation towards the base of stalk. Flowers green. Calyx lobes rounded or subreniform, 0.5 by ¾-1 mm. Petals elliptic, or broadly ovate, 1.25-1.5 by 1 mm, reflexed at anthesis, obtuse or slightly acute. Disk fleshy, cup-shaped, margin slightly crenate. Stamens 1-1.5 mm, attached just beneath the margin of the disk; filaments subulate, fleshy, slightly flattened; anthers slightly ovoid, c. 1/3 mm long, slightly apiculate. Pistil flask-like, the base adnate to the disk; style very short; stigma capitate. Fruits ellipsoid or sometimes slightly obovoid, 5-7 by 4-5 mm, obtuse, 1(-2)-seeded, sustained by the usually persistent floral parts.
