Abstract:—High grasslands are complex environments that feature a rich flora with a high degree of endemism, particularly for Bromeliace�. The Serra da Pedra Branca is located in the municipality of Caldas, southern region of Minas Gerais, part of the geomorphologic region of �Planalto Dissecado do Sul de Minas�, extending over 368 ha of the �Santu�rio Ecol�gico da Pedra Branca�. The predominant vegetation types are montane and high montane semideciduous seasonal forests and �campos de altitude� (high altitude grasslands). A survey carried out in Serra da Pedra Branca between March 2008 and February 2009 revealed the occurrence of 14 species of Bromeliace�, belonging to six genera: Tillandsia (six spp.), Vriesea (three spp.), �chmea (two spp.), Billbergia, Bromelia and Wittrockia (with one sp. each). Most of the species are distributed between 1400 and 1700 m of altitude, however, the larger populations are found above 1700 m, comprising �chmea distichantha, Vriesea sceptrum and Wittrockia cyathiformis. Descriptions of species, identification key, illustrations and ecological, taxonomic and geographic distribution comments are presented.
