Calantica chauvetiae Sleumer Adansonia , sér. 2, 12: 543 (1973) . — Type: Madagascar , Prov. Toliara , gorges du Fiherenana , en aval d’Anjamala, 20.I.1962 , fl., fr., Service Forestier 20854 ( holo- , P ! [ P02141576 ] ; iso- , P ×4!, L [photo seen]). DISTRIBUTION AND HABITAT The only existing collection of Calantica chauvetiae is from southwestern Madagascar in the region of the Fiherenana River. REMARKS Calantica chauvetiae is described as a shrub. Sleumer incorrectly labelled both one of the type collection’s duplicates at P and the duplicate at L as “holotype” with typed labels in 1972. The published protologue ( Sleumer 1973: 543 ) makes it clear that the P duplicate is the holotype and the L duplicate is an isotype. CONSERVATION STATUS The preliminary assessment of the conservation status of Calantica chauvetiae is Critically Endangered (CR B2ab(iii)). With an Area of Occupancy of less than 10 km 2, it is known only from a single location, which is not protected and is subject to continuing habitat degradation.
