Imidica, Lundstr., are synonyms as far as they ha ve reference to mere varieties of 
the species liere in question, and so also is the case with S. cordifolia, Pursh, at 
least when it is used for arctic specimens. I have also made use of several state- 
ments where the author only speaks of »willow», »dwarf» or »groundwillow», as 
1 think these records to be referable to this species, even if I must admit that some, 
for instanee from southern Baffin Land, especialiy when they are described as 
»almost a shrub», may perhaps bear upon S. glanca also. 
? Salix Macounii, Rydb. 
Distribution. [Mansfield Island, Bell (ex Rydberg, Wiilows)].

S. arhutifolia, Taylor, Pl. Baff. 
Distribution. Victoria Land: Prince Albert Sound, Andeeson (ex Hooker, ColL, Akm-

it in Klutschak'8 collection also, and Balfour in Taylor's. Andersson has several other records 
of wiilows which are impossible to identify, among them a new species, S. arbusculoides, described 
in Mon. Sal., p. 147, and afterwards by himself (de Oandolle, 1. c, p. 248) renamed S. humillima. 
The locality given for this is the same as the above-mentioned of Hooker, but as collector 
Miertsching is natned. 
74. Salix uva ursi, Pursh. 
Distribution. Baffin Land: White Strait, Tarr (ex Rowlee & Wiegand, 
Cornell list). 
Geographic area. Eastern arctic and subarctic America, White Mountains. 
This beautiful little species is found nowhere else in the Archipelago, but as 
it is so characteristic that it can hardly be confounded with any other and as its 
distribution does not make its appearance in Baffin Land improbable, I think I am 
right in entering it in the list on the authority siated above.

S. polaris, Hooker, Coll. (ex parte ?). 
Distribution. jBoothia Felix ?. John Ross (NHM); Melville Peninsula:
