An updated molecular phylogeny of the Ericaceae.

The Ericaceae is a large (~4500 species) family which is essentially cosmopolitan, but rare in tropical lowlands. The family is morphologically diverse, particularly in floral morphology, but also includes highly modified leaves in some clades. We will present the first update of the phylogenetic relationships within the Ericaceae since the 2002 study of Kron etal. That study sampled approximately 90 species within all major clades and analyzed two molecular markers within a Maximum Parsimony framework. The current study seeks to add several additional molecular markers, many additional taxa, and Maximum Likelihood and Bayesian analyses. Using the new phylogeny, we also carried out an analysis of historical biogeography using Mesquite and RASP(Reconstruct Ancestral State in Phylogenies, Yu Yan). We will discuss any major rearrangements of relationships, improvements in the resolution and support within the Ericaceae tree, and major biogeographic patterns.
