 mountain back of Kadiak village, F. A. Walpole, 1900 (No. 11S2). 

 Specimens of this willow were brought from a mountain back of

 not preserved. 



Alaska Penitisula. — At Kukak Bay, Coville and Kearney (Nos. 

 1618, 1680), Trelease and Saunders (No. 34S2). 



The history of this species, briefly stated, is as follows : In the year 

 1 888 Mr. M. S. Bebb published two closelv related new species of 

 willows, commutata ^ and conjuncta,'^ which he considered interme- 

 diate hetw een g-lauca and cor data. Later, in the light of further col- 

 lections, he recognized and alluded to ^ the close relationship of these 

 species with the older Salix Barclay i of Andersson and his own Salix 

 calif ornica.^ Still later he described^ Barclay i as a species exhibit- 

 ing " a degree of variation remarkable even among willows," and was 

 inclined to refer to it as synonymous his coffi??iutata and co7zjuncta, an 

 inclination to which he afterward yielded as evidenced by his identifi- 

 cations of willows sent to him from the National Herbarium. From 

 the large series of specimens now available and from field observation 

 of these willows in the Cascade Mountains and in Alaska, I do not 

 hesitate to express the opinion that Salix barclayi and Salix commu- 

 tata are two valid species, and that conjuncta is a synonym of bar- 

 clayi. No botanist with mature leaf specimens of the two plants be-
