Discussion

Bark texture and foliage features have been used to distinguish geographic varieties or segregate species. Although bark texture may be consistent within populations, over the species as a whole there is complete intergradation between smooth and fibrous barks. Various forms are commonly cultivated and sometimes persistent in the southern United States.
