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.
