The saxicolous genus Orthophytum (∼60 species, Bromeliaceae) is endemic to eastern Brazil and diversified in xeric habitats of the Atlantic Rainforest, Caatinga and campos rupestres. Within the genus, two main groups are discerned based on the presence or absence of a pedunculate inflorescence, which are further subdivided into several morphological subgroups. However, these systematic hypotheses have not yet been tested in a molecular phylogenetic framework. Here we present the first phylogenetic analysis of Orthophytum using nuclear and plastid markers (phytochrome C, and trnH-psbA and trnL-trnF spacers)...
