number of species in close genera of 4 & upwards

number of species having vars

number of vars


(The total number of species having vars is 88 ) omitting the 4 genera

[243v]

The total number of species is with 4 genera omitted 662 [-] 339 [=] 323

In genera having 4 species & upwards there 339

In genera having 3 species & under the 323 species

In the 339 species in the large genera ie 4 & upwards have 51 species presenting vars —

In the 323 species in small genera ie 3 & less 37 present vars. But as below, there ought to have been 48.5

In proportion of 339 : 323 [x] 51 [=] 16473 [÷] 339 [=] 48.5 :: 51 : 48.5

(New Zealand)

Conclusion

The 339 species in large gen have 51 with vars

The 323 ought to have 48.5 — they have really 37

The above 339 species in large genera have 94 varieties

― 323 sp. in small genera have 76, they ought to 89 1/2

So that the Rule holds with the number of vars. themselves, but not in same proportion for as the 51 species in the large genera have 94 vars, the 37 species in small genera ought to have had only 68.1 vars, but they have really 76, ie 8.1 too many vars

NB The plan wd be to calculate as

339 : 323 [x] 37 [=] 11451 [÷] 339 [=] 3 :: 37 : X 323 : 339 :: 37 : X» 323 : 339 [x] 37 [=] 12443 [÷] 323 [=] 38.5 : 37 : X = 38.5
