- Family: Euphorbiaceae

- Species: Euphorbia ankaranae
The specific epithet ankaranae is derived from the Ankarana region of northern Madagascar, indicating the area where the species was first collected or is primarily found.
Description
Euphorbia ankaranae is characterized by its succulent growth form, typical of many Madagascan Euphorbia species that inhabit arid or xeric substrates. Detailed morphological data (such as stem size, leaf arrangement, flower structure, and latex characteristics) are recorded in specialist taxonomic treatments, but comprehensive descriptions are not widely disseminated in general reference works.
Distribution and Habitat
The species is endemic to Madagascar, with occurrences reported from the Ankarana Massif, a limestone plateau noted for its karst topography, sinkholes, and cliffs. It typically grows on limestone outcrops and rocky substrates where drainage is rapid and soil is shallow.
Discovery and Nomenclature
Euphorbia ankaranae was formally described by the botanist Werner Rauh, a specialist in succulent plants and African flora. The original publication details (journal, year, page) are recorded in botanical databases such as the International Plant Names Index (IPNI) and Tropicos, but are not reproduced here.
Conservation
The International Union for Conservation of Nature (IUCN) has not evaluated Euphorbia ankaranae for the Red List, and therefore its conservation status remains formally unassessed. However, many endemic Madagascan succulents are considered vulnerable due to habitat loss, quarrying, and illegal collection.
