growth. In the marked development of branches from the base 

 there is increased growth or at least development of buds that 

 usually remain dormant. 



There is no series of characters of either H. oculiroseiis or H. 

 Moscheutos that can be considered as combining in hybridization 

 to give the dwarf. 



The simultaneous appearance of variations involving modifi- 

 cations of groups of characters and of intermediates of various 

 kinds exhibit sporadic variations of various degrees of intensity 

 quite in line with the general evidence of the sporadic nature and 

 wide range of such variations.
