DESCRIPTION

Large shrub or small tree, to 10 m tall. Twigs terete, densely pubescent, the hairs erect, the indument wearing off with age; terminal buds densely pubescent. Leaves alternate, chartaceous, 6-13 × 2.5-7 cm, elliptic to broadly elliptic, base obtuse or acute, tip acute or acuminate, lateral veins 5-6 on each side, midrib and lateral veins impressed above, tertiary venation immersed, midrib, lateral veins and tertiary venation raised on lower surface; upper surface with scattered, erect hairs, the indument denser on midrib and lateral veins, lower surface pubescent, the hairs erect; domatia lacking. Petioles 0.4-1.2 cm long, with similar indument as twigs. Inflorescences axillary, pubescent, c. 5 cm long, rather few-flowered, bracts sometimes present at anthesis.Tepals pubescent on both surfaces, but less so on inner surface, 1.5-2 mm long. Stamens 9, 4-celled, 1.5 mm long, filaments pubescent, anther glabrous, staminodia 3, pubescent, stipitiform. Ovary and inside of receptacle glabrous.

REMARKS

This species has frequently been confused with Ocotea grayi   and differences between the two are discussed under O. grayi   . Vegetatively, the impressed midrib and lateral vein on the upper leaf surface and the pilose lower leaf surface are characteristic.
