Chimantaea

[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.
