Comparative phylogenetic resolution of Pinus species used in this study. Resolution from A) two chloroplast loci  and B) our complete alignment. Distance bar corresponds to 100 nucleotide changes, and is scaled for either tree. * indicate branches with < 95% (likelihood) bootstrap support in B) (likelihood and parsimony topologies were completely congruent).
