Willow are very cross-compatible, and numerous hybrids occur, both naturally and in cultivation. A well-known ornamental example is the weeping willow ("Salix × sepulcralis"), which is a hybrid of Peking willow ("Salix babylonica") from China and white willow ("Salix alba") from Europe. The hybrid cultivar 'Boydii' has gained the Royal Horticultural Society's Award of Garden Merit. Numerous cultivars of "Salix" L. have been developed and named over the centuries. New selections of cultivars with superior technical and ornamental characteristics have been chosen deliberately and applied to various purposes. Most recently, "Salix" has become an important source for bioenergy production and for
Salix pedicellata cylindrical, about 1.25 mm long and 0.5 mm wide. "Salix pedicellata" was first described by René Desfontaines in 1799. "Salix canariensis" is treated by some taxonomists as a subspecies of "S. pedicellata", under the name "S. pedicellata" subsp. "canariensis", so that the species "S. pedicellata" becomes "S. pedicellata" subsp. "pedicellata". It hybridizes with "Salix atrocinerea". "Salix pedicellata" is native to some of the countries around the Mediterranean, in Europe (Portugal, Spain, mainland Italy, Sicily, mainland Greece and Crete), western North Africa (Morocco, Algeria and Tunisia) and Western Asia (the East Aegean Islands, Turkey and Lebanon-Syria). It has been introduced to
