DISTRIBUTION AND HABITAT. — Scolopia manongarivae is restricted to the northern province of Antsiranana and a small adjacent portion of Mahajanga ( Fig. 6 ); it is found at moderate to high elevations, sometimes along streambanks. Habitat types include sclerophyllous forest, moss forest, and at lower elevations cloud and valley forest; it is reported to occur on laterite.

REMARKS

Scolopia manongarivae is a tree to 15 m tall. The leaves are persistent and coriaceous, with many weak wavy secondary veins; they dry green, often to olive beneath, or less often brown. Most specimens from lower elevations have large, broad leaves (usually 5.5-9.5 cm long, but relatively short-petioled) with often conspicuous venation. A few specimens from the highest elevations, around Tsaratanana, have much smaller and more strongly coriaceous leaves; these may represent a genetically distinct local variety or a phenotypic response to extreme altitude. The flowers are white to pale yellow, with yellow to red glands. The adaxial surface of the sepals and petals is pubescent and the perianth is accrescent in fruit, with sepals elongating to 2.5-3 mm. Fruits are usually described as green, rarely as reddish, but fully ripe fruits may never have been collected.

VERNACULAR NAMES

Telotritry (Gautier & Chatelain 2782; Miller & Randrianasolo 4478).

CONSERVATION STATUS

Scolopia manongarivae is known to exist at 13 locations; though its minimum Area of Occupancy is only 64 km 2, it has an Extent of Occurrence of 12005 km 2 and a potential maximum Area of Occupancy of c. 4500 km 2 based on the remaining area of possibly suitable forest within the EOO. The preliminary assessment of its conservation status is therefore Near Threatened (NT). While it occurs in the Protected Areas of Anjanaharibe-Sud, Manongarivo, Marojejy, and Tsaratanana, there is likely to be decline outside of those protected areas.
