Note Salix is a genus of over 500 species, widespread except in Australia and the South Pacific. In north temperate regions, species of Salix are frequently the dominant species, especially along watercourses and in marshes and other wet places. Salix wood is used in some countries for basketry, for building dykes and locks and for support for mud-covered houses. Trees are often fast growing.
