Ethesia xanthochlora, distribution, ecology, habitat, taxonomy, Tankwa Karoo


As a part of a taxonomic revision of Ethesia Raf., a new species, E. tanquana Mart.-Azorín & M.B.Crespo, is described from the Tanqua Karoo in South Africa. This new species is at first sight similar to E. haalenbergensis (U.Mu.ll.-Doblies & D.Mu.ll.-Doblies) Mart.-Azorín, M.B.Crespo & Juan and also E. xanthochlora (Baker) Mart.-Azorín, M.B.Crespo & Juan, but it differs in floral and vegetative characters as well as in its ecology and isolated distribution. A complete description, data on biology, habitat, and distribution of the new species are presented. An identification key for Ethesia and new data on the rare Namibian E. haalenbergensis are also given.
