The family Bromeliaceae in the Ibitipoca State Park, Minas Gerais, Brazil

Abstract

The Ibitipoca State Park (Parque Estadual do Ibitipoca - PEIB), in southeastern Minas Gerais, Municipality of Lima Duarte, has an area of 1923.5 hectares, at altitudes varying between 1100 and 1784 m. Its vegetation is a mosaic of Atlantic forest and"campo rupestre". Within the studied area 11 genera and 32 species of Bromeliaceae were found, amongst them one endemic species (Vriesea cacuminis) and one known only from the type collection (Neoregelia oligantha), namely Vriesea (8 spp.), Tillandsia (7 spp.), Aechmea, Neoregelia (3 spp. each), Billbergia, Nidularium, Pitcairnia (2 spp. each), Wittrockia, Dyckia and Alcantarea (1 sp. each). The most representative populations are found in nebular forests above 1400 m. The majority of the species (20) has a distribution restricted to the Atlantic forest domain. Identification keys, descriptions, illustrations and comments for each species are provided.
