Lastly
Of genera with 5 species & upwards there are ― with 4 & 3 species — with 2 & 1 spec |
sp 251 157 254 |
sp with var 35 22

Hence we see that the very large genera & very small genera have nearly equal number of vars !!

[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—
