The Origin of Linaria Vulgaris Peloria. 207 



on the highest lateral twig below the main flDwer- 

 spike. 



The qnestion snggests itself, Is the power of i)ro- 

 dncing isolated peloric flowers inherent in all plants of 

 Linaria vulgaris} Or are there two races, one with and 

 one without this faculty? This question seems not to 

 have been investigated as yet. 

 From the observations already 

 described it must be concluded 

 that this point can never be de- 

 termined in the field, for the 

 absence of the abnormality on 

 ]:)articular days, or even in par- 

 ticular years proves nothing in 

 itself. Personally I think it 

 likely that both kinds exist and 

 that there are localities for Li- 

 naria vulgaris in which these ab- 

 normalities are never found. 



Holland however is not one 

 of these. By paying attention 

 to them when out on an expe- 

 dition, one will find isolated pe- 

 loric specimens fairly frequently 

 and in the most diverse localities. 

 When I wanted a specimen to 

 photograph for an illustration (Fig. 41), I asked my 

 wife to look for one in the neighborhood, and it was 

 not long before I had one. The power to produce them 

 is, therefore, widely distributed in this country; and 

 also obviously heritable although in a latent state as a 

 rule. Whether or no there are localities in which this 

 character does not occur, I cannot tell.
