1 always removed the stamens of all Iris flowers out early each morning, 

 and no flower not hand-fertilized set a pod that year. The resulting 

 seedlings in each case were quite uniform to type, and about what 

 might be expected from the cross. Here where there are more bees 

 I have many bee-crossed pods of seed every year, and I have sowed 

 a few. The resulting seedlings are never uniform in type, and are 

 sometimes very mixed. 



The crosses were made in 1906 and the last seedling flowered 

 in 1917, but the majority flowered before 1912. As regards the 

 characters, no record was made of any difference of intensity of the 

 colouring of the leaves. The tipping of the beard does not seem 

 to be a sharply marked character (with the varieties used), and I 

 found a difficulty in classing the cases where the tipping was weak 

 or slight, but I give the figures as I recorded them, noting these doubtful 

 cases. The classing of the colours of the flowers proved unexpectedly 

 easy, the criterion of the division between the two classes being 

 presence or absence of yellow. Thus they are practically divided 

 into " blue " or blue-purple toned Neglectas and Amcenas on the one 

 side, and more or less reddish-toned yellow-suffused Squalens and 

 Variegata on the other. (This division was chosen the first year 

 of flowering when less than half had flowered.) In the cross G. 189 — 

 a Variegata by an Amcena — there were no Squalens, the dividing line 

 was very sharp, and it almost looks as if Amcena and Variegata were 

 allelomorphic colour varieties. In the same way Neglectas appear 

 to be Squalens in which the yellow factor is suppressed or absent.

* C. 8. a. and E. 233 were early seedlings, long since " scrapped," and at 

 that time I did not use any negative symbols, simply recording a character 

 if present and making no record if absent ; thus the beard and leaves of C. 8. a. 

 and the beard of E. 233 are not definitely recorded as being not tipped and not 

 coloured, but I think there is no doubt that they were not.
