genus Lens Simpson, 1900: cladomics
13 Recent valid species (13 total species)

Cladomics Summary

number of species = 13 (13 total)
analyzed in 64 cladograms in 41 publications
maximum number of terminals in an analysis = 11 (mean = 2.84, median = 1.5)

Basic Monophyly

number of cladograms that test basic monophyly (i.e., more than 1 included species) = 32
maximum number of included terminals = 11, (mean = 4.69 median = 4)
proportion of cladograms that support basic monophyly = 0.94

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.
