Contribution to the description of an endemic Turkish Salix species.

摘要

Salix rizeensis A. Guner et J. Zielinski is an endemic species and was recorded from NE Turkey in 1993. Since the generative organs could not be collected, its description was based only on sterile shoots. In this study, specimens of both sexes were collected for the first time and their description, new to science, is given together with the line drawings. The species shows most resemblance to Salix caesia Vill. as regard to both generative and vegetative characters, and belongs to section Helix Dumort. Subsection Ceasiae A. Skvortsov..
