Vochysiaceae of Serra do Cipo, Minas Gerais, Brazil.
This work presents a taxonomic treatment of species of Vochysiaceae occurring in Serra do Cipo, Minas Gerais, Brazil, conducted by herbarium and field observations. Serra do Cipo comprises part of the southern segment of the Espinhaco Range, characterized by shallow, sandy, acidic and nutrient-poor soils, in which are common quartzite formations in the form of folded rock structures and sandstone outcrops. The vegetation is mostly comprised of “campos rupestres” associated with other vegetation types such as “cerrados” and forests. We have found 22 species belonging to four genera: Callisthene (4 spp.), Qualea (4 spp.), Salvertia (1 sp.), and Vochysia (13 spp.). There are proposed synonymizations of Vochysia cipoana Stafleu and V. martiana Stafleu with V. rotundifolia Mart. and V. pygmaea Bong., respectively, and the recognition of a new species of Vochysia, and a new subspecies of C. microphylla. Six of these species are endemic to Minas Gerais, and the new Vochysia species is the only exclusive of Serra do Cipo. The floristic comparison with 11 other localities showed that the Serra do Cipo has the highest number of species among the surveys analyzed. Diamantina was the region with more species in common with the Serra do Cipo, with three species occurring only in these two localities.
