peats its type only in a very small proportion 

 of its seed. 



All in all we thus have a group of a dozen new 

 types, springing from an original form in one 

 restricted locality, and seen to grow there, 

 or, arising in the garden from seeds collected 

 from the original locality. Without any doubt 

 the germs of the new types are fully developed 

 within the seed, ready to be evolved at the time 

 of germination. More favorable conditions in 

 the field would no doubt allow all of the de- 

 scribed new species to unfold their attributes 

 there, and to come into competition with each 

 other and with the common parents. But ob- 

 viously this is only of secondary importance, 

 and has no influence on the fact that a number 

 of new types, analogous to the older swarms of 

 Drab a, Viola and of many other polymorphous 

 species, have been seen to arise directly in the 

 wild state.
