DISTRIBUTION AND HABITAT. — Scolopia meridionalis occurs in transitional forest and dry bush in southern Madagascar ( Fig. 2 View FIG ). Most collections are from two localities in the extreme southeast; a single collection from the southwest, at the massif of Analavelona, is atypical (see discussion below).

REMARKS

Scolopia meridionalis is usually a small tree to 6 m or a large shrub, often with spiny branches, that belongs to the group of xerophytic species with one-flowered inflorescences. It is distinguished from others in that group by its obovate to rhomboid, usually 2-5 cm long leaves and pubescent ovaries. The only collection from the disjunct population at Analavelona was a tree 15-20 m tall with platanoid bark. Although formal taxonomic recognition of this population was not possible given the very limited available material, it may be suspected that it represents at least a distinct subspecies. Further investigation would be desirable.

CONSERVATION STATUS

The preliminary assessment of the conservation status of Scolopia meridionalis is Endangered (EN B1ab(iii)+2ab(iii)), with an Extent of Occurrence of 1675 km 2, and a minimum Area of Occupancy of 12 km 2. It is known only from older collections at three locations, two very close together in an area of the extreme southeast subject to continuing habitat degradation and one, whose population may well be genetically and taxonomically distinct, far to the west at Analavelona.
