50 ¢ Canadian Arctic Expedition, 1913-18 
The occurrence of Populus tremuloides here, about Lat. 67-5°N., is inter- 
esting. The species has previously been observed on Hulahula river, Alaska, 
by Dr. Anderson! and in the delta of Mackenzie river. These three localities 
therefore indicate its approximate northern limit on this continent.? 
South Side of Coronation Gulf 
A few points concerning the vegetation in general has been given on the 
preceding pages under topography; and as I did not visit the region myself I 
can only give a list of the known flowering plants, compiled from the published 
records of plants collected. Apart from a small collection made by R. M. 
Anderson at the mouth of Kogaryuak river, 18 miles east of Coppermine river, 
June 18th, 1911, I only know, of more recent collections, Hanbury’s along this 
coast in 1902. Members of the Southern Party of the Canadian Arctic expe- 
dition secured, in 1914 to 1916, fairly representative collections of plants at 
certain points, viz.: Tree river, cape Barrow, outer part of Bathurst inlet, 
besides smaller collections at Grays bay and the inner part of Bathurst inlet. 
These collections were made by Messrs. J. J. O’Neil, J. R. Cox, and R. M. Ander- 
son. Hanbury’s plants were identified by R. A. Rolfe? and the locality is 
merely given as the Arctic coast from Ogden bay to Coppermine river. From 
Hanbury’s narrative! it appears, however, that coming from the east he first 
began collecting plants in June at Bathurst inlet, and we can therefore make 
use of his full list. Anderson’s plants from Kogaryuak river in 1911 were 
identified by P. A. Rydberg.® 
The vascular plants collected by the Southern Party of the Canadian 
Arctic expedition were identified by J. M. Macoun and Theo. Holm.* In the 
following list, species not secured by the Canadian Arctic expedition in the region 
in question are marked with an x.

7 As these plants have been identified by three different botanists, it is probable that some of them are the same, 
although listed under different names. This refers particularly to, e. g. Stellaria longipes, Caltha palustris, Lupinus noot- 
katensis, Oxytropis campestris, Armeria vulgaris, Matricaria inodora, Senccio palustris. j
