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.
