REMARKS

Scolopia inappendiculata is a small tree or large shrub with platanoid bark. It is the only species found around Mahajanga, and is distinguished from species of the xerophytic group known from the extreme north by its larger, often shortacuminate leaves and few or absent spines.

CONSERVATION STATUS

The preliminary assessment of the conservation status of Scolopia inappendiculata is Endangered (EN B1ab(iii)+B2ab(iii)). It is known from at most four locations in the region of Mahajanga, with an Extent of Occurrence of 1161 km 2 and a minimum Area of Occupancy of 16 km 2; the maximum potential Area of Occupancy is certainly less than 500 km 2 given that much of the area within the EOO polygon consists of the delta of the Betsiboka River. The species has not been recollected for almost fifty years, despite the accessible terrain, and the limited remaining natural vegetation in the area is subject to continuing habitat degradation.
