CLASSIFICATION AND CHART 



THE American Dahlia Society has adopted 

 the following nine classes into which the 

 forms of dahlias may be divided. The defi- 

 nitions are as clear as possible, and the sub- 

 divisions place the hybrids. It has been a 

 difficult problem to solve, and yearly becomes 

 more so, for new varieties are constantly appear- 

 ing which either blend the forms of two classes 

 or are so totally different that it is almost im- 

 possible to classify them. 



CLASS I. 



CACTUS DAHLIAS 



(a) True, fluted type: Corollas long, narrow, incurved 

 or twisted, with sharp or fluted points and with the mar- 

 gins re volute (rolled backward or outward), forming in the 

 outer florets a more or less perfect tube for more than half 

 the length of the corolla. 



Typical examples: Pierrot; Mrs. Douglas Fleming; 

 J. H. Jackson; Valiant. 



(b) Hybrid cactus or semi-cactus type: Corollas short 

 as compared with previous type, broad, flat, recurved or
