DISTRIBUTION AND HABITAT. — Scolopia calcicola is known only from a single collection, from Montagne des Français in the extreme north ( Fig. 2 ). REMARKS Notes from the type indicate that Scolopia calcicola is a spiny large shrub or small tree (“arbuste”) with platanoid bark. It is distinguished from other species in the xerophytic group by its small obovate leaves and glabrous ovary. CONSERVATION STATUS The preliminary assessment of the conservation status of Scolopia calcicola is Critically Endangered (CR B2ab(iii)). The single known location has not been protected, though efforts are currently underway to provide it some degree of protected status, and the area has suffered obvious anthropogenic degradation. Since the area of Montagne des Français is relatively often visited by botanical collectors, the lack of additional specimens is evidence that the population is likely to be small.
