77. Salix reticulata, L. 
Distribution. Victoria Land: Minto Inlet (KH) and Cambridge Bay, Ander- 
son (ex HooKER, Coll.); King William Land: Gjöa Harbour, Lindström (ex Osten- 
FELD, Gjöa Exp.); [Boothia Felix ?, John Ross (NHM)]; North Sommerset: Port 
Kennedy, Walkp:r (ex Hooker, Exp. Fox); [Melville FeninsuLa: Duckett Cove, Parry 
(NHM); Mansfield and Nottingham Islands, Bell (ex iMacoun, Cat.)J; Baffin Land: 
Big Island, Tarr (ex Rowlee & Wiegand, Cornell list), Scotts Bay, Taylor (Pl. 
Baff.), Ponds Bay, Walker (ex Hooker, Exp. Fox), Borden (ex Macoun, App. 
Neptune), Port Bowen, J. C. Boss (ex Hooker, App. Parry III). 
Geo gra ph i c area. Arctic and subaretic North America, Rocky Mountains, 
arctic and subaretic parts of Asia and Europé, and mountains to the south. 
Notwithstanding the many records from Baffin Land I am somewhat in doubt 
about the occurrence there, as no specimens are available. The close resemblance 
to this which broadleaved forms of S. arctica may assume always makes an error 
possible. 
Betulaceae, Ag. 
78. Betula nana, L. 
Distribution. Baffin Land: Cumberland Gulf, Kumlien (Plants). 
Geographic area. Greenland, Labrador, Hudson Bay region, western arctic 
North America (?), Siberia (?), Nowaja Semlja, Spitzbergen, northern parts and moun- 
tains of central Europé. 
It is rather curious that Kumlien alone should have found the dwarf birch 
in Cumberland Gulf, the more so, as Taylor expressly states to have looked for 
it in vain (Pl. Baff., p. 330), but the only mistake possible is a confusion of this 
species with B. ghndnlo^^a, Michx., such as has often taken place and still makes 
the areas of both species indistinct. Most probably, liowever, the identification is right.
