Chimantaea is a genus of flowering plants in the aster family, Asteraceae.[1][2]
This genus[3] is endemic to the Pantepui,[4] a biogeographic province on the Guiana Highlands in Venezuela, Guyana, and Brazil.[5] The region is characterized by a pattern of about 50 tepuis, isolated tabletop mountains that arise from the sandstone plateau of the highlands.[5] Tepuis are known for their biodiversity, especially their concentrations of endemic species, and most are still pristine, undisturbed ecosystems.[5] The genus is almost entirely restricted to the Chimantá Massif, a complex of several of these tepuis in Bolívar, Venezuela.[4] There several species of the genus are dominant members of the higher-elevation shrublands, which are known as paramoid vegetation because of their similarity to the páramos of the Andes.[6]
- Species
All the species are endemic to Venezuela.[7]
