Stem

Shrub or small tree to 12 m tall. Branchlets glossy, cream to tan yellow, lenticellate with age, glabrous.

Leaves

Leaves simple, alternate, subverticillate or subopposite, young leaves with ferruginous hairs, becoming sparsely hairy or hairless. Stipules present, scale like, triangular-ovate to 1.7 mm long. Petiole 0.2-2.4 cm long. Leaf blade elliptic-oblong, narrowly elliptic, oblanceolate or obovate, rarely falcate, 3-17.2 cm long, 1.2-6.4 cm wide, ± flat. Base cuneate to attenuate, margin entire to slightly wavy or undulate, flat to recurved (rarely revolute) apex acute to rounded, rarely retuse. Midrib slightly raised above, prominently raised below at base of blade, tapering to flush toward apex. Lateral veins curving but forming only indistinct loops inside the blade margin.

Flowers

Inflorescences are axillary, occasionally arising along internodes below axils, and fasciculate. Both male and female flowers produced on the same plant. Buds in axils of leaves are often seen as gnarly clusters interspersed with scale like bracts. Male flowers: pedicels filiform, 1.5-5 mm long; sepals 5, rarely 6,(in other profiles referred to as tepals), apices hooded and ciliate internally; petals 0-5 present, to 2.5 mm long, disk conspicuous rounded, fleshy; stamens 4-5. Female flowers: on filiform pedicels 2-14 mm long, glabrous or with sparse to scattered ferruginous hairs; sepals 5 (in other species profiles they are referred to as tepals), to 3 mm long, apices hooded, internally densely ciliate, green. Petals 0-3 present, 2.5 mm long. Disk conspicuous, fleshy, annular to 5 lobed, ovary with sparse tortuous ferruginous hairs present. Styles 3, fused at base and stigmas 3.

Fruit

Pedicels 3-25 mm long. Capsules depressed-globose, ovoid or rounded, 11-13.5 mm diam., strongly bullate, dehiscing at maturity, olive green. Sepals persistent at the base of the fruit. Seeds 6-7 mm long, 5-6.5 mm wide, dark olive; caruncle poorly developed. Cotyledons well developed in mature seed, thick and folded.
