 took the type of the variety. These intermediate leaves shade

tudied the plant in the field, that the broad glabn 

 leaves were the extreme form, were they not accompanied by an 

 extreme in floral development which is more significant than the 

 leaf characters on which Prof. Rowl< the variety. 



This is in the development of the secondary aments at th 

 of the terminal. In the variety the aments often form clusl 

 of half a . all opening at nearly the same time a thing 



which is rarely seen in S. interior itself. The flowering period is 

 also distinctly later in the variety than in the species. ( )n
