VERNACULAR NAMES. — Varongirwinbakoka, varongy, varongy fotsy, varongi mainty.


Tree, to 25 m. Twigs terete, yellow-brown tomentellous when young, glabrescent; terminal buds tomentellous. Leaves 9-19 × 4-9 cm, alternate, tripliveined, chartaceous, elliptic to broadly elliptic, base acute or obtuse, apex acute or acuminate, lateral veins 3-5; upper leaf surface initially pubescent, soon becoming glabrous, venation immersed, lower surface with a sparse to dense indument of erect, curled hairs, venation clearly raised; domatia present, consisting of shallow pockets covered by a dense tuft of hairs. Petioles 0.8-1.5 cm long, with a similar indument as the twigs. Inflorescences (densely) pubescent, paniculate-cymose, in axils of leaves, to 12 cm long. Flowers creamy white to pale yellow, tepals 6, pubescent on both surfaces, c. 2 mm long; stamens 9, all 4-celled, 1 mm long, filaments pubescent, anthers glabrous, glands present at the base of the inner stamens, staminodia stipitiform, pubescent. Ovary and inside of the receptacle glabrous. Fruit roundish, c. 2 cm in diameter, cupule deeply cup-shaped, to 2.5 cm wide, 1.5 cm high.


Ocotea grayi   is characterized by the presence of domatia, tripliveined leaves, erect indument on lower leaf surface and its rather long inflorescences. Most collections placed in this species were previously identified as Ocotea trichophlebia Baker. This   latter species differs from O. grayi   in its pinnately veined leaves, lack of domatia and smaller leaves and inflorescences. Ocotea trichophlebia   also occurs at higher elevations than O. grayi   .
