But if Families with 2 genera be added other proportion is 14.6. !!!

Here only 14 genera with 1 species in each.

35 x 8 = 280 genera

Genera of all kinds exactly single species

306

Orders with 3 genera in each

[table not transcribed]

See whether as in case of orders with 2- genera by renaming only a few orders, the number per genus can be reduced

306v

Orders with 4 genera in each

[table not transcribed]

307

Class or alliance with 3 orders do with 2 or 1 order

[table not transcribed]

Orders in alliance & in 1 class

Hence each oder has on average 22.93 ~~genera~~ average in class 27.6

[table not transcribed]

Genera of all kinds exactly those with single species
