Salix Euxina
''Salix euxina'', the eastern crack-willow, is a species of flowering plant in the willow family Salicaceae, native from Turkey to the Caucasus. It was first described by I. V. Belyaeva in 2009. It is one of the parents of the common crack-willow, ''Salix'' × ''fragilis''. Description ''Salix euxina'' is a tree that can reach 15–20 m high with a trunk diameter of up to 1 m. It has a wide crown, and old trees develop deeply fissured bark on their trunks. The olive green branchlets are hairless (glabrous) and very brittle at the base, so that branches easily break off. These are able to root and propagate the species. The leaves are pale green and glabrous. They have stomata only on the undersurface. The catkins are relatively thick with somewhat densely clustered flowers.
