In Hookers Flora of New Zealand, there (with those in Supplement)

of Phanerogams Subtract on account of variability & size Veronica 1. Carex 1 Coprosma 1 Senecio 1 4

Genera 288         4 Genera 284

sp. 24 22 19 19 84

sp. 746 N. B. If these 4 genera had not been excluded the result wd. have been more striking 84 662 species

So for one calculations these 284 Genera —with 662 species

Of these 284 genera 70 67 have either one or more species with one or more vars. & these 70 67 genera include 326 266 species, so have on average

67)266 (3.97

70/326 (4.6species to each genus.

Consequently the remaining genera (284 - 70 67 =) 2147 include (682 - 326 266 =) 396 species, not having one offering a var. so that these genera have on average

214/336 (1.57

217/396 (1.82 Hence, the genera having one or more species presenting vars marked by Greek letter, contain rather more than twice the species on average, than do those genera with no vars. —

(Hooker told me that he rather objected to introduction of vars.)

à (The 67 genera have only 86 species with vars. ie on average each genus has 1.28 species with vars. But the 86 species have altogether, 168 vars, so that Each species has on average almost 2 vars each. —)
