Under the above numbers there are several plants that will 
perhaps some day be separated from this typical species, which, 
as above enumerated, includes many difi'erent forms : in some 
the leaves are pale, of larger size, and cordate at base ; often 
they are regularly oval, frequently are darker and rigidly coria- 
ceous, sometimes smaller, broadly ovate, upon longer and more 
slender petioles ; and this last form will probably constitute a 
distinct species, as well as another with oblong acute leaves. 
The leaves are l;f-2| inches long, lff-2|- inches broad, on a
