Caption: "Combined 4-gene analysis of rbcL, atpB, 18S, and 26S; strict consensus of the shortest trees. All character changes are included. Of 5923 characters, 2205 were phylogenetically informative. Jackknife values are above branches, branch support below." Notes: Newick file was adapted from TreeBASE file. Pinus and Picea species were collapsed to genus, Conifers were plucked from a larger tree, and hybrid species were pruned. Karla Sartor 2008-03-12
