Discussion

Species 7 (7 in the flora).

All of the species in sect. Cordatae, with the exception of Salix turnorii, were treated by R. D. Dorn (1995) as subspecies or varieties of S. eriocephala. These taxa have relatively distinct ranges and, although they hybridize where they come into contact, their integrity is not jeopardized. For those reasons, they are treated here as species.
