Statistics for most parsimonious trees derived from analyses that were constrained to agree with alternative phylogenetic hypotheses. Consistency index excludes uninformative characters. Value for Templeton test (P, calculated in PAUP 4.0b10) is the probability of finding a more extreme T-value under the null hypothesis of no difference between the two trees (two-tailed test), arbitrarily calculated by comparing the first tree in each of the two alternative tree lists. Results in bold are those that are present in the Adams consensus of all equally parsimonious trees. OS = ordered and scaled analysis; U = unordered analysis; NA = not applicable.
