SELECTED SPECIMENS SEEN. — Centre: Massif de l’Ankaratra, <i>Service Forestier (Capuron) 11961,</i> (MO, P[P01955950, P01955951], TEF); Massif du Vohibe <i>-</i> Antoetra, S-SE d’Ambositra, <i>Service Forestier (Capuron) 23856</i> (MO, P); Fianarantsoa, Parc National de Ranomafana, <i>Rakoto 377</i> (MO, P[P01955949], TAN); Fianarantsoa, forêt de Ankazomirady <i>Rakotomalaza 709</i> (MO). DISTRIBUTION. <i>— Ocotea perforata</i> is known from several collections, made from Ambositra, to the Ankaratra mountains, between 1300 and 1800 m altitude. PHENOLOGY. — Flowers: December, (old) February; young fruits: April; mature fruits: February. VERNACULAR NAMES. — Varongy, varongy mainty. DESCRIPTION Small tree, to 12 m. Twigs somewhat angular, glabrous, the bark gray and warty; terminal buds glabrous. Leaves alternate, firmly chartaceous, 7-10 × 2-4 cm, elliptic or narrowly elliptic, base acute or gradually narrowed into the petiole, apex acute, glabrous on both surfaces, midrib, lateral veins and tertiary venation immersed in both surfaces, lateral veins 5-8 on each side, faintly visible; domatia present, consisting of deep pits, with a glabrous, small, slit-like opening, in the axils of the lateral veins as well as along the lateral veins. Petioles glabrous, 5-8 mm long, sometimes poorly differentiated from the lamina because of the decurrent base. Inflorescences axillary, basally glabrous, distally becoming pubescent, 4-7 cm long. Flowers puberulous.Tepals 6, spreading to reflexed in old flowers, pubescent on inner surface <i>c.</i> 2.5 mm long. Stamens 9, 4-celled, 1.3 mm long, glabrous, except for few hairs at base of filaments, staminodia glabrous. Inside of receptacle and ovary glabrous. Detached fruits 1.9 × 1.4 cm: detached cupule shallowly cup-shaped, 1.3 cm in diameter, <i>c.</i> 4 mm deep. REMARKS <i>Ocotea perforata</i>, as here accepted, is characterized by the presence of pit domatia along the lateral veins and glabrous twigs and terminal buds.Domatia may also be present in the axils of the basal lateral veins. It is a species known from the high mountains in central-south Madagascar. I have decided to place the recently described <i>O. oligantha</i> in synonymy of <i>O. perforata</i>; its distribution is the same as for <i>O. perforata</i>, and it shares the glabrous twigs and terminal buds as well as the presence of domatia along the lateral veins. It was recognized largely on its wider leaves. A recent collection has leaves intermediate in width between <i>O. oligantha</i> and <i>O. perforata</i>, which makes the vegetative characters used to separate the two species tenuous.
