Randomly-chosen most parsimonious tree resulting from cladistic analyses of combined matK/trnL-F/ITS rDNA data set for the mainly pseudobulbless groups of the tree. Values above branches are Fitch lengths; values below branches are bootstrap percentages followed by Bayesian posterior probability values if > 95; an asterisk indicates posterior probability value <95. Black squares indicate nodes that collapse in the strict consensus tree. Vol. 5, N 2
