Abstract
The current knowledge of the Bromeliad Flora of the state of Chiapas, Mexico, is presented. Based on the study of 5,495 herbarium specimens corresponding to 3,233 collections, and in a detailed bibliographic revision, we conclude that the currently known Bromeliad Flora of Chiapas comprises 133 species and 14 genera. With 21 endemic taxa, corresponding to the genera Hechtia (1 sp.), Pitcairnia (7 spp.), and Tillandsia (13 spp.), Chiapas occupies the second place in endemism after Oaxaca. The catalog of the species, as well as generic and specific identification keys, and distribution maps of all taxa are included.
