The variety differs from the species in having the leaves nearly 

 entire, a few usually completely so in some plants, though, as a rule, 

 the apex at least is distinctly lobed. The white woolly indument 

 characteristic of this species is often so reduced in amount as to make 

 the stems and leaves appear green rather than the typical cottony 

 color. The several different aspects have been assigned specific values 

 in the North American Flora.
