genus Ortmanniana Frierson, 1927: cladomics
2 Recent valid species (2 total species)

Cladomics Summary

number of species = 2 (2 total)
analyzed in 53 cladograms in 32 publications
maximum number of terminals in an analysis = 2 (mean = 1.09, median = 1)

Basic Monophyly

number of cladograms that test basic monophyly (i.e., more than 1 included species) = 5
maximum number of included terminals = 2, (mean = 2 median = 2)
proportion of cladograms that support basic monophyly = 0

Pairwise Cladogram Clustering

The graphs below depict in two dimensions all pair-wise ingroup distances within the cladome. See the Cladmoics FARQ for more information.
