Hab. 



Prov. Kanhok : in paludosis Kinkok tractus Kyojyo (T. Nakai no. 

 6841 S , 6842 9 ) ; in paludosis inter Moho & Nojido (T. Nakai 

 no. 1938) ; ibidem (M. Furumi no. 438 fr.) ; in paludosis districtus 

 montis Paiktusan (T. Mori no. 88 fr.). 



Distr. Manshuria. 



This variety is chiefly distinguished from var. typica by having the 

 young leaves whitish or brownish silky. Salix finnmarckica Willdenow 

 or Salix rugulosa var. finnmarckica has rugose leaves. So, it is not rea- 

 sonable to reduce it to Salix myrtilloides as Trautvetter and Meyer did.
