A hybrid between Salix triandra and S. xanthicola, occurring in the Rhodope Mountains in northeastern Greece, is described as a new nothospecies. It differs from S. triandra by having distinctly hairy young stems and more deeply serrate-dentate leaf margins, and from S. xanthicola by a smooth, unstructured (without conicoids) wax layer on the lower side of the leaves and the presence of subsessile glands on the petioles.
