[total] 159 / 15

There are 159 species with 1 species in genus & these have only 15 species presenting vars

On other hand 95 species in genera with 2 sp. each present 16 species So that they vary more than the monotypic genera —

∴ No progression. —

On whole I think best way to divide into great masses—
