Salix hallaisanensis is the earliest valid name for this species since 

 the East Asiatic Salix Caprea is distinguished from the Europaean 

 type. Salix hallaisanensis is a glabrescent variety while the variety 

 orbicularis or Salix Hulteni Floderus represents a sericeous variety. 

 The writer's knowledge of Europasn Salix Caprea is only by the dried 

 specimens. As he did not care much about Salices in Europe, he is 

 not able to make a good judgement on the method of distinguishing 

 between Salix Caprea and Salix Hulteni employed by Dr. Floderus. 

 However, the Korean specimens agree perfectly with the descriptions 

 of Salix Hulteni. Mr. Kimura distinguished the Japanese type of Salix 

 Caprea from the continental form as in the former the longitudinal 

 striations on the woody part are seen when the bark is stripped off. 

 Dr. Ueki, Professor of the Higher Forest School at Suigen has given 

 the similar test on the Korean plant upon my request, and found that 

 the Korean form has also the striation as the Japanese type.
