This is old list made a year or two ago, but I have marked it. C.D July 1857

(Conclusion)

Hence we see under what may be called a Fourth Category, viz forms which are considered even by Babington (3d Edit) as varieties, & distinguished by Greek Letters that there are enumerated 250. But I shd state that genera Rubus, Rosa, Hieracium, Salix & Carex are omitted; & further that a very few varieties have been excluded, these being rather alluded to, than fully admitted by Babington. I say there are 250 varieties belonging to 182 species, belonging to 117 genera as admitted in Loudon Catalogue, which I have taken as standard of comparison to save time.

These 117 )250 genera in the Loudon Catalogue have 607 species, hence each genus on average has 5.18.— Now the standard of comparison, or average in the Loudon Catalogue for all genera (the 5 excluded) we have seen is only 2.63. So that Babington vars. (vars which are or have been species in eyes of some very few Botanists) follow same law & belong on average to the larger genera. —
