DISTRIBUTION AND HABITAT. — Scolopia montana is mostly known from low- to mid-elevation humid forests ( Fig. 2 ); the highestelevation collection (1700 m) was said to be on laterite.

REMARKS

Scolopia montana has small, oblanceolate to narrowly oblong leaves, with rounded to obtuse (or rarely cuspidate) apices and cuneate to convex bases, that dry greenish-brown to olive adaxially and brownish abaxially. The pedicels are short in flower; they remain under 2.5 mm in most fruiting specimens but reach 7-8 mm in one. The perianth is probably somewhat accrescent in fruit, but available material does not suffice to confirm this.

CONSERVATION STATUS

The preliminary assessment of the conservation status of Scolopia montana is Near Threatened (NT). Collections are known from only five locations, but these include the Protected Areas of Anjanaharibe-Sud, Betampona, Masoala, and Zahamena, which reduces the risk that it will be endangered in the near future. Its Extent of Occurrence is 24 078 km2, and although its minimum Area of Occupancy is 20 km 2, the estimated potential maximum Area of Occupancy based on likely suitable habitat within the Extent of Occurrence exceeds 2000 km 2.
