The Phylogeny and Morphology of the Brazilian Gaultheria species .

There are six species of Gaultheria that are endemic to the Mata Atlantica (Atlantic rainforest) in Brazil. Several exhibit unique morphological characters within Gaultheria. Gaultheria bradeana, G. myrtilloides, G. serrata and G. ulei all have the typical Gaultheria fruit morphology (capsular fruit surrounded by a colored fleshy calyx). However, G. itatiaiae and G. sleumeriana have capsular fruits and dry calyces which are only present in some species of Gaultheria in New Zealand (G. colensoi, G. crassa, G. oppositifolia, G. paniculata and G. rupestris) as well as one species in temperate South America (G. nubigena). Gaultheria bradeana has the unusual characters of fleshy pedicels and bracteoles. Gaylussacia corvensis has recently been identified as a new species of Gaultheria and this taxon exhibits capsular fruits with only slightly fleshy calyx lobes. The endemic Brazilian species of Gaultheria have never been examined in a phylogenetic analysis. Analyses of both chloroplast and nuclear data, including all Gaultheria species present in Brazil (except G. ulei), indicate that these morphologically diverse species are monophyletic with strong support.
