Phylogenetic relationships of 35 pines and four outgroups as determined from ycf1 and ycf2 partitions. A) ycf1 only. B) ycf2 only. C) ycf1 and ycf2 combined. Support values are only shown for nodes with bootstrap/posterior probability values less than 100%/1.0, and are shown as ML bootstrap/MP bootstrap/BI posterior probability. Dashes indicate < 50% bootstrap support or < .50 posterior probability, * indicates topological difference between either parsimony or Bayesian analyses and ML. Accessions whose position differs from that in full alignment analysis indicated in bold.
