Maximum-likelihood phylogeny of the 69-taxon TB29 data set. This data set was composed of up to 590 bp. Among the ingroup, 22 characters were parsimony-informative. Estimated ML model parameters conform to the GTR+G model of sequence evolution. -ln L = 1485.985421, rate matrix: A-C = 0.724474, A-G = 2.026332, A-T = 0.393397, C-G = 0.419566, C-T = 1.269648, G-T = 1. Base frequencies: A = 0.31, C = 0.21, G = 0.19, and T = 0.29, and γ-shape parameter = 0.8245. Thick branches indicate nodes with ≥ .95 BPP and ML and MP bootstrap values ≥ 70.
