D. EVER-SPORTING VARIETIES 



Lecture XI 



STRIPED FLOWERS 



Terminology is an awkward thing. It is as 

 disagreeable to be compelled to make new 

 names, as to be constrained to use the old 

 faulty ones. Different readers may associate 

 different ideas with the same terms, and unfor- 

 tunately this is the case with much of the 

 terminology of the science of heredity and 

 variability. What are species and what are 

 varieties? How many different conceptions 

 are conveyed by the terms constancy and varia- 

 bility? We are compelled to use them, but we 

 are not at all sure that we are rightly under- 

 stood when we do so. 



Gradually new terms arise and make their 

 way. They have a more limited applicability 

 than the old ones, and are more narrowly cir- 

 cumscribed. They are not to supplant the older 

 terms, but permit their use in a more general 

 way.
