The partial phylogram is based on a strict consensus of two most-parsimonious trees (2050 steps) obtained for a 3-gene (nucLSU, atp6, tef1) dataset (compiled by & © T. Osmundson, 2009) using constraint and random sectorial searches, parsimony ratchet (200 iterations), and tree fusing (5 rounds). Bootstrap support values (percent of 1000 replicates) appear above branches.
