Origin of Wild Species 603 



issions we may ptate that wild new elementary 

 Jecies and varieties are recorded to have 

 ppeared from time to time. Invariably this 

 appened by sudden leaps and without interme- 

 iates. The mutants are constant when prop- 

 gated by seed, and at once constitute a new 

 ice. In rare instances this may be of sufficient 

 ciperiority to win a place for itself in nature, 

 at more often it has qualities which have led to 

 s introduction into gardens as an ornamental 

 lant or into botanical gardens by reason of the 

 iter est afforded by their novelty, or by their 

 Qomaly. 



Many more mutations may be supposed to be 

 iking place all around us, but -artificial sowings 

 a a large scale, combined with a close exam- 

 lation of the seedlings and a keen appreciation 

 F the slightest indications of deviation seem 

 squired to bring them to light.
