Great Bear Lake (Pullen) . 
On the banks of the river Buckland this speeiea is a tree from sixteen to twenty feet high, forming 
thickets ; in Kotzebue Sound it reaches the height of about eight feet ; at Cape Lisbnrne it is two feet 
high, and further to the north, not seen. 
Plate X. Fig. 1, brunch with male flowers j 2 and 3, male flowers ; 4, branch with female flower ; 
6, oviii-j- and stylo ; 7, catkin with ripe carpels ; 8, ripe carpel : — all, except 1, 4, and 7, magnified. 
189. Salix Richardsoni, Hook. Fl. Bor. Amer. vol. ii. p. 147. t. 172. From Kotzebue Sound 
to Cape Lisburne. 
The specimens collected in Western Eskimaux-land difier from those collected on the Mackenzie river, 
by Iianug the ovaries covered with a slight down. No other diiference is perceptible. 
190. Salix Uva~ursi, Pursh; dccumbcns, ramis foliisque pubescentibus vel dcniuni glabris, foliis 
conaceis obo\atis vel oblongis obtusis vel emarginatis integerrimis vel versus basim subdenticidatis 
supra nitidis subtus glaucescentibus, stipulis caducis, amentis coEetanois terminalibusj squamis. 
cuueato-obovatis obtusis pilosis ovario multo brevioribus, ovariis glabcrrimis, stigmatibus bipar- 
titis. ^ .—Pursh, Fl. Amer. Sept. vol. ii. p. 610. Wainwright Inlet ; between Point Barrow and 
Mackenzie River [Pullen); Kotzebue Sound, and Island of St. Paul (Ckamisso). 
Without authentic specimens it is almost impossible to determine any of the Willows, except a few 
well-marked species. Of S. Uva-ursi nothing appears to be known save the short diagnosis given in the 
Fl. Amer. Sept., and Pursh himself does not seem to have seen any but cultivated specimens. I do not 
think, however, that I am wrong in naming the specimens before me S. Uva-nrsi. Both Erman and Cha- 
miBSO gathered specimens agreeing with those collected by myself and Pullen. Chamisso, according to a 
manuscript note in the Hookerian Herbarium, referred his with a query to 8. mi/rtilhides, but that species 
is always erect, even when growing in Laplnnd, and has thin, delicate leaves, while S. Tlva-ursi is decum- 
bent, and has a thick, coriaceous foliage. If I am right in referring all the specimens to one species, the 
geographical range of 8. Uva-ursi extends from Siberia to Labrador.
