The species seems to be fairly constant in all its essential characters. As in other 
species, the leaves are somewhat variable but within definite limits. Figure 38 rep- 
resents the typical leaf form exhibited by the greater number of specimens. Figure 
39 shows a leaf outline characteristic of the southern representatives of the species. 
There seem to be no concomitant characters which, combined with the difference 
in leaf form, might separate the northern and southern plants.
