DISTRIBUTION AND HABITAT. — Scolopia thouvenotii   is found in humid eastern montane forests in the province of Toamasina at low to moderate elevations ( Fig. 2 View FIG ).


Scolopia thouvenotii   is a tree up to 30 m tall, with dbh to 40 cm. The ovate to elliptical or occasionally lanceolate leaves are small, persistent, and brown on drying, with a blunt-tipped long-caudate to narrowly acuminate apex. The flowers are white, the pedicels short, and the fruits reportedly green, though probably seen only when immature. Means of distinguishing it from S. taimbarina   have been remarked above. It also could be confused with S. hazomby   , which occurs in the same region, and which has more oblong to elliptical leaves and a usually convex (to cuneate) rather than rounded base. From existing material, the upper end of the leaf size range for S. thouvenotii   is about 6.5 cm long with a 6 mm petiole, whereas this is the lower end of the typical mature leaf size range for S. hazomby   , which also has much longer petioles.


Hazomby (Louvel 119, Thouvenot 84); Hazomby à petites [sic; probably “petites feuilles”] (Louvel 190); Menavahatra (Antilahimena et al. 5335); Taimbaritra (Perrier de la Bâthie 4661).


The preliminary assessment of the conservation status of Scolopia thouvenotii   is Vulnerable (VU B1ab(i,ii,iii,iv,v)). It is known from no more than ten locations and has an Extent of Occurrence of 16 246 km 2 and a minimum Area of Occupancy of 56 km 2, with an estimated potential maxi- mum Area of Occupancy based on likely suitable habitat that exceeds 2000 km 2. Most of the habitat is unprotected and subject to continuing degradation, although the species does occur in the Protected Areas of Andasibe-Mantadia, Masoala, and Nosy Mangabe. We project a decline in population size and suitable habitat at the Ambatovy mining site in the near future.
