Tending To Vary 



The wild dahlia evidently had unusual propensity to 

 vary; otherwise it would hardly have been possible to develop 

 the extraordinarily complex flowers that are now to be seen in our 

 gardens within the comparatively short period of time since the 

 dahlia was brought under cultivation. Here we see illus- 

 trated the tendency to variation even among 

 flowers growing from the same stem.
