Abstract

Velloziaceae currently comprises five genera and approx. 250 species, with mainly amphiatlantic distribution. The majority of the species is present Neotropical region, and in Brazil, the family is represented by Barbacenia and Vellozia, comprising 213 species. Over the years, delimitation of the genera, and also at infrageneric levels, caused controversy among taxonomists. In recent phylogenetic reconstructions using Bayesian and Parsimony inferences, Barbacenia formed two basal clades. One of them comprises only endemic species from Brazilian inselbergs s.l., with Barbacenia fanniae, B. gounelleana, B. irwiniana, B. mantiqueirae, B. purpurea and B. spectabilis. Its sister-clade includes the 44 other species of Barbacenia analyzed, all of the Archipelago Campo Rupestre, in central/south-eastern Brazil. Considering that these analyses did not cover all species of Barbacenia from inselbergs, the present study aims to expand sampling effort including all species that occur in these localities of Brazil, in order to test the monophyly of the group. We also aim to estimate the divergence times among species and between the two lineages of Barbacenia in order to better understand the floristic relationships between the Brazilian inselbergs and Campo Rupestre. For the resolution of phylogenetic and biogeographic questions, we will analyze four plastidial markers (atpB-rbcL, trnH-psbA and trnL-trnF spacers, and trnL intron) and one nuclear (ITS nrDNA). Parsimony and Bayesian Inference will be used for phylogenetic reconstructions. The divergence time of the two Barbacenia lineages will be estimated using Cyclantaceae and Triuridaceae fossils to calibrate the phylogenetic dating. The reconstruction of ancestral areas will be achieved by DIVA analyses, minimizing events of dispersion and extinction. A morphological analysis also will be performed to understand the evolution of the characters in a phylogenetic context in the Barbacenia inselbergs clade. (AU)
