Trees inferred from the maximum maximum likelihood analysis (A) and maximum parsimony analysis (B) of nucleotide sequences of 13 single-copy genes. Picea sitchensis was used as the outgroup taxa for all analyses. Branch lengths are proportional to the number of expected nucleotide substitutions; scale bar corresponds to one substitution per hundred sites for the ML tree and to 100 changes for maximum parsimony tree. Non-parametric bootstrap values (greater than 50%) are indicated by the colored bars placed on branches.
