Tropical hyperdesertic to pluviseasonal, upper infra- to low supratropical and upper ultrahyperarid to upper dry, and occasionaly lower subhumid (short period years), are the bioclimates in these archipelago. Biogeographically they are situated in the Paleotropical Kingdom, Afrotropical Sub- kingdom, Tropical Saharan Region, and Cabo Verde Province. Eight new species are described: Acacia caboverdeana, Asphodelus mariolousae, Frankenia pseudoericifolia, Hyparrhenia caboverdeana, Lotus chevalieri, Polycarpaea caboverdeana, Suaeda caboverdeana and Tetraena vicentina, and also fifteen new combinations are proposed. In taxo- nomic phytosociology, five new classis: Cocculo penduli-Sarcostemmetea daltonii, Heteropogonetea contorti, Tetrae- netea simplicis,
