number of species = 2
analyzed in 24 cladograms in 12 publications
maximum number of terminals in an analysis = 2, mean = 1.08
Basic Monophyly
number of cladograms that test basic monophyly (i.e., more than 1 included species) = 2
maximum number of included terminals = 2, mean = 2.0
proportion of cladograms that support basic monophyly = 1.0
