NATHORST (N. W. Gronl.), at first excluded this species from the list, 

 notwithstanding the statements about it in the works of HAYES and DUR- 

 AND; but afterwards he inserted it, as he found 'birches" mentioned, 

 also by KANE (I Grinnell Exp., p. 143). Now indeed both these evid- 

 ences are of somewhat doubtful value, but later on it has been recorded 

 from our district by WETHERILL also, and is consequently to be recko- 

 ned as a citizen of the area. 



Occurrence. S. Cape York (WETHERILL); between that point and 

 Cape Dudley Digges (KANE); Port Foulke (HAYES). 



Distribution: East and West Greenland, Labrador, Hudson Bay 

 region, 1 Novaja Semlja, Spitsbergen, Russia, Scandinavia, Prussia, moun- 

 tains of Middle Europe, Scotland, Iceland. 



Salicaceae. 

 Salix arctica, PALL. 



S. arctica, SIMMONS, Fl. Ellesm.; OSTENFELD, Plantes N. E. Gronl. 



Under this name I feel myself fully justified in uniting all the 

 Salices, reported from Greenland north of Melville Bay, with the sole 

 exception of S. herbacea. INGLEFIELD, SUTHERLAND, KANE, HAYES, DUR- 

 AND, BESSELS, HART, and NATHORST have used the name ''arctica" with 

 either BROWN or PALLAS as author. "S. Brownii" is mentioned by 

 WETHERILL, "S. glauca" by KANE and WETHERILL, "S. lanata" by 

 KANE, "S. uva ursi" by KANE. Even without having seen the speci- 

 mens th'us determined, I cannot doubt that they all belong to the multi- 

 form ,S. arctica. For particulars about the different forms and their 

 synonymic, I must refer to my Fl. Ellesm., p. 130132, and to the lite- 

 rature quoted there, especially LUNDSTROM, Weid. Nov. Semi.; here, it 

 may be enough to point out that S. uva ursi, PURSH, is a species of 

 far a more southerly distribution, found nowhere in Greenland. The same 

 is the case with S. lanata, L. (with the exception of some indetermin- 

 able, sterile specimens in the Copenhagen herbarium, conf. LANGE, Consp. 



1 Several authors, indeed, for instance HOOKER (1. c.) and J. D. HOOKER, Outl. of 

 Distrib., have given it a far wider range in America; but, in the northwest at 

 least, B. glandulosa, MICHX., has certainly been taken for it by the earlier 

 botanists, who have reported B. nana, which has also been the case in several 

 parts of Asia. Therefore even the statements about its distribution in LEDEBOUR, 

 1. c., are not to be indiscriminately used, even though it is not improbable, that 

 the present species is spread also in Asia.
