Checklist of the Bromeliaceae from Pedra dos Pontões, Mimoso do Sul, Espírito Santo, Brazil, with four first records for the state

Bromeliaceae is one of the most relevant taxonomic groups of the Atlantic Forest, where the Brazilian southeastern region stands out as a center of diversity and endemism for many taxa of the family. We present a checklist of the 12 genera and 44 species of Bromeliaceae from the Pedra dos Pontões, in Mimoso do Sul municipality, Espírito Santo state, southeastern Brazil. The Bromelioideae (22 species) was the subfamily with most taxonomic diversity, followed by Tillandsioideae (18 species) and Pitcairnioideae (four species). We also report the first occurrence of four species (A. squarrosa, N. antoineanum, V. pseudoatra and V. pardalina) for the Espírito Santo state. Almost half of the taxa surveyed inhabit exclusively the vegetation associated to the rocky outcrops, what points out the importance of this kind of environment in the maintenance of the diversity for many species of bromeliads. We also highlight that the documentation and study of the flora of Espírito Santo, which is considered a gap in the knowledge of the plant diversity along the entire Brazilian Atlantic Forest, assumes a relevant aspect in view of the high levels of degradation of the natural ecosystems observed in the state.
