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 Ethiopia. Salix pedicellata Salix pedicellata is a species of willow. It is a shrub or small tree to about 6–8 m tall, native around the Mediterranean Sea from Portugal to Lebanon and Syria in the north and from Morocco to Tunisia in the south. "Salix canariensis" may be treated as a subspecies of "S. pedicellata". "Salix pedicellata" is very variable in appearance. It forms a shrub or small tree up to 6–8 m tall. Its trunk may be up to 1.4 m, but is usually shorter. Its twigs are dark brown, initially with short hairs (tomentose), later smooth (glabrous). If
