DISTRIBUTION. — <i>Ocotea cymosa</i> has a wide distribution along the eastern slope, from Farafangana in the south to Andapa in the north. It ranges from the coast to 1500 m altitude. PHENOLOGY. — Flowering: May-August, mostly in June-July; fruiting specimens collected throughout the year. VERNACULAR NAMES. — Varongy, varongy mainty, antafonana, tafonona, tafononana. DESCRIPTION Trees, to 20 m. Twigs ridged, appressed pubescent, becoming glabrous with age; terminal buds densely appressed pubescent. Leaves 6-17 × 2-8 cm, alternate, chartaceous, elliptic, glabrous, the base acute, apex shortly acuminate, densely and minutely gland-dotted on the lower surface, lateral veins 5-8, reticulation fine and raised on both surfaces, domatia absent. Petioles glabrous, flat above. Inflorescences appressed pubescent, paniculate-cymose, 2-4 cm long, grouped along leafless short shoots in the axils of leaves. Pedicels appressed pubescent, as long as the flowers. Flowers <i>c.</i> 5 mm in diam., tepals half-erect. Tepals elliptic, 3 mm long, sparsely pubescent on both surfaces, stamens 9, all 4-celled, 1-1.5 mm long, glabrous or nearly so; staminodia 3, small, stipitiform, pubescent; pistil glabrous, 2 mm long, receptacle cup-shaped, appressed pubescent inside. Fruit ovoid, 20 × 18 mm, cupule cup-shaped, 2.5 cm wide, 1.5 cm deep, tepals not persistent on the cupule. REMARKS <i>Ocotea cymosa</i> is a frequently collected species, best recognized by the minute and raised reticulation on both surfaces of the leaves, the short inflorescences arranged along leaf less short shoots and the glanddotted lower leaf surface. It can be confused with <i>O. nervosa</i> Kosterm., but that species has a lax (and raised) reticulation and longer inflorescences. <i>Ocotea nervosa</i> is also infrequently collected.
