Botanische Jahrbücher für Systematik, Pflanzengeschichte und Pflanzengeographie 109: 75 (1987) GoogleMaps   . — Type: Madagascar, Menagisy   GoogleMaps , Brickaville, [18°52’S, 49°04’E], 8.XII.1956, fl., Service Forestier 12355 (holo-, P; iso-, TEF).


Tree of unknown size.Twigs terete, glabrous; terminal buds glabrous. Leaves opposite, elliptic to narrowly elliptic, 6-11 × 1.5-3 cm, glabrous, firmly chartaceous, the base acute to attenuate, apex bluntly acute, margin flat, the upper surface shiny,reticulation immersed on the upper surface, weakly raised on the lower surface; lateral veins hard to discern; petioles 6-10 mm long, canaliculate. Inflorescences to 4 cm long, glabrous; pedicels c. 2 mm long.Flower buds slightly depressed globose, c. 1.5 mm in diam., glabrous, tepals about as long as wide, stamens 6, thick, glabrous, locelli subapical, staminodia III with a peltate tip, free, with two glands at the base; staminodia IV small, subulate. Pistil glabrous. Fruits unknown.


This species is only known from the type collection ( Fig. 8 View FIG ) and is best recognized by the small flowers with 6 stamens and the rather long, flexible inflorescences. The type has few flowers or flower buds left and the description given above is largely taken from Rohwer’s description and illustration (Rohwer


& Richter 1987). The description is brief and reflects the poor quality of the type specimen.


Flowers: December.
