Salix babylonica a gold-yellow in autumn. The flowers are arranged in catkins produced early in the spring; it is dioecious, with the male and female catkins on separate trees. "Salix babylonica" was described and named scientifically by Carolus Linnaeus in 1736, who knew the species as the pendulous-branched ("weeping") variant then recently introduced into the Clifford garden in Hartekamp in The Netherlands. Early Chinese cultivar selections include the original weeping willow, "Salix babylonica" 'Pendula', in which the branches and twigs are strongly pendulous, which was presumably spread along ancient trade routes. These distinctive trees were subsequently introduced into England from Aleppo in
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
