PHENOLOGY. — Flowers: October; fruits December.


Shrub. Twigs terete, slender, glabrous; terminal buds glabrous. Leaves 6-11 × 2-3.5 cm, alternate, chartaceous, elliptic or narrowly elliptic, glabrous, the base acute, apex acuminate, upper surface smooth, lower surface with the 7-9 lateral veins weakly raised; domatia lacking. Petioles glabrous, 6-10 mm long. Inflorescences in the axils of deciduous bracts, glabrous, paniculate-cymose, 5-8 cm long, laxly flowered. Pedicels slender, 1-1.5 cm long. Flowers glabrous, tepals spreading; tepals 6, 2- 2.5 mm long, the inner surface with a few hairs near the base; stamens 9, all 4-celled, c. 1.3 mm long, filaments about as long as the anthers, inner stamens with 2 glands at the base; pistil 2 mm long, glabrous; receptacle deep, glabrous inside. Cupule cup-shaped, 1.5 cm wide, 0.8 cm high, pedicel scarcely thickened; fruit ellipsoid, 2 × 1.5 cm.


This species is readily recognized by its glabrous condition, acuminate leaves and the slender inflorescences with long-pedicelled flowers.Only three other species share the glabrous condition: O. madagascariensis   , which has obtuse, somewhat obovate leaves with coarse, raised reticulation, O. sambiranensis   , which can be recognized by its raised reticulation, presence of small gland dots on the lower leaf surface and shorter pedicels and O. glaberrima   sp. nov., a small shrub with small, obtuse leaves.
