The complex of species related to Salix purpurea is one of those groups within the genus Salix L. that are the most challenging for understanding.So far there is neither consensus, nor sufficient clarity in interpretations of this group in the literature.The situation with the species from East Asia is the most uncertain: at least 14 species have been named there by different authors in addition to S. purpurea.
