Shrubs or trees, 0.2–8 m. Buds alba-type and intermediate. Leaves: stipules on late ones foliaceous; largest medial blade (rarely amphistomatous), 2–8 times as long as wide, adaxial surface not glaucous. Staminate flowers: filaments glabrous or hairy basally. Pistillate flowers: adaxial nectary shorter than stipe; stipe 0.6–4.2 mm; ovary glabrous; stigmas with flat, non-papillate abaxial surface, or stigmas cylindrical, or plump, 0.1–0.4 mm.
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.
Selected References
None.
