Untangling two Chinese Salix species (Salicaceae) published by C. K. Schneider, with lectotypification of four names

Salix rhoophila C. K. Schneid. was originally described based on three collections. The specimens in these collections belong to two different taxa: S. rhoophila as currently recognized and a species that until now has usually been called S. alfredii Goerz cx Rehder & Kobuski. The original material of S. polyclona C. K. Schneid. and S. mictotricha C. K. Schneid. also represent the same two species. The names S. alfredii, S. mictotricha, S. polyclona and S. rhoophila are lectotypified. The orthography of S. wuana K. S. Hao ex C. F. Fang & A. K. Skvortsov is corrected (originally spelled as "Wuiana"). Salix affredii, S. mictotricha and S. wuana are recognized as synonyms of S. polyclona.
