Phylogeny of the 112 species ofViburnumsampled in this study. Presented is the Bayesian majority rule consensus tree of the combined chloroplast and nrITS data. Asterisks above the branches indicate posterior probabilities greater than 0.95. The named clades within Viburnum proposed by Winkworth and Donoghue [26] and Clement and Donoghue [15] are shown to the right, and the underlined clade names are those used in the hierarchical comparisons (see text). Thick red and blue branches mark Viburnum species that occur in Japan and in Mexico and Central America, respectively. The chloroplast and nrITS partitions were each analyzed under a GTR + I + G model of sequence evolution. Resulting tree statistics and rate parameters are as follows: -lnL = 14052.08; chloroplast partition – rate matrix = 0.2398, 0.1810, 0.0819, 0.0903, 0.1738, 0.2331, basepair frequencies = 0.3224, 0.1643, 0.1700, 0.3435, G = 0.0602, I = 0.7412; nrITS partition – rate matrix = 0.0662, 0.2027, 0.0490, 0.0341, 0.6076, 0.0405, base pair frequencies = 0.1913, 0.3203, 0.2880, 0.1989, G = 0.7646, I = 0.4152.
