764 PLANT LIFE OF ALABAMA. 
This variable species comprises two forms which are closely connected by inter- 
mediate forms and difficult to separate, although the extreme forms from the moun- 
tain region appear quite distinct by the petiolate, broader, less acuminate, and more 
coarsely serrate leaves, From the material examined in the National Herbarium 
this form appears to prevail in the Northern States. Specimens trom the coast pine 
barrens agree exactly with the description of Michaux, having the stem divided 
above into long, slender, few-leaved fastigiate branches bearing a rather close corymb, 
and the acuminate leaves with the truncate base sessile. May prove a good variety.
