One of three equally most parsimonious
trees shown as a phylogram obtained from
comparative sequence analysis of combined
trnL-F, atpB-rbcL, rps16 and matK
sequence data. Values above branches
represent the number of steps supporting
each branch. Values below branches
represent the percentages of bootstrap
supporting each branch. Arrow head
represents node not supported by strict
consensus.
