shores of Hudson Bay. The species has also been reported from 

 southwestern Greenland by Durand (in Jour. Acad. Nat. Sci. Phil. 

 II. 3:197 [PI- Kaneanae Groenl.] 1856), but Lange (Consp. Fl. 

 Groenl. 1:108. 1880) made the following statement: "S. Uva Ursi 

 Durand ex descriptione (PI. Kan.) ad formam nostram 3 [S. arcio- 

 phila lejocarpa] retuli, etsi specimina Kaneana non vidi, quare 

 dijudicare nequeo, an forsan ad veram S. Uva Ursi Pursh .... 

 pertineant, species, quae tamen a nemine aHoquin in Groenlandia 

 lecta esse constat." I am inclined to believe that Kane's specimens 

 represented the true 5". Uva-ursi, because this species is apparently 

 identical with 5. Myrsinites parvifolia Lange and S. ivigtiitiana 

 Lundstr. Lange said that he did not see specimens of the t>^ical 

 S. Myrsinites L. from Greenland, and his var. parvifolia seems to be 

 distributed from about the 70th parallel to the very south in Green- 

 land. I have seen one specimen from the Tunugdharfik Fjord, 

 Kingua, Ig. L. K. Rosenvinge, August 17, 1888 (fr.; G.), which 

 fully agrees with Lange 's and Lundstrom's descriptions, and, in 

 my opinion, cannot be separated from 5. Uva-ursi, the presence of 

 which may be expected in this part of Greenland. The leaves are 

 distinctly glaucous beneath, while they are green and shining on 

 both sides in 5. Myrsinites. Andersson's var. lahradorica (1868) 

 from near Oakak on Labrador is scarcely different from the type. 

 He based it on Hohenacker's no. 92% which I have not yet seen. On 

 the other hand, the forms referred to 5". Uva-ursi by Hooker (Fl. 

 Bor.-Am. 2:152. 1839) seem to belong at least partly to 5. arcto- 

 phila, but I have as yet seen only a few leaves of Morrison's speci- 

 men in Herb. Bebb in C. which do not have stomata in the upper 

 epidermis, as is always the case in Pursh's species. 



7. S. Peasei Fernald in Rhodora 19:223. 191 7. — This willow 

 is known only from the type locahty in New Hampshire, southwest 

 gully of King's Ravine on Mt. Washington, where it was first 

 collected by Pease (no. 12091; the type is Fernald and Pease, 

 no. 16847, fr.; G.). It is certainly a very peculiar species, and 

 needs further observation, the male plant being still unknown. 

 Fernald's description is, as usual, ample and fitting. I am almost 

 sure that it has to be regarded as of hybrid origin. I visited King's 

 Ravine on September 18, 1918, and I found the willow growing in
