HYBRIDS — 17 
Hyprips. 
Where two species grow in close association, individuals are 
occasionally to be found which are not referable to any known 
species, and which combine more or less the characters possessed 
separately by the species with which they are growing, and also 
at the same time present other features not shown by their 
associates. Such individuals occur sporadically, and only in close 
association with two or more distinct species. Hitherto I have 
plants as hybrids is very strong, and, indeed, to anyone seeing 
these plants growing side by side with the supposed parents it is 
quite convincing. ; 
_ A feature of all these hybrids is the very characteristic altera- 
tion in form of the stipules. These become enlarged, the base of 
the stipule is much broadened, and the lateral lobes are carried 
a long way up the stipule and are often shortened. This form of 
hybrid nature of a plant, evenif I did not see this plant associated 
with its supposed parents. 
The following hybrids have been recognized :— 
petals suffused with blue; petals not longer than the sepals. 
Growing with both parents at Wallasey, Cheshire (H. and 
H. Drabble).
