LIST OF PLANTS COLLECTED ON THE STEFANSON- 

 ANDERSON ARCTIC EXPEDITION, 1908-12 



By p. a. Rydberg 



A small collection of arctic and subarctic plants was recently 

 turned over to me for naming. They were collected rather 

 incidentally by Professor R. M. Anderson and kindly donated by 

 him to the New York Botanical Garden. One species of Astra- 

 galus is probably new and several of the plants are very rare. 

 The list is by no means complete as to the vegetation of the 

 region, but may be of some interest. 



Smith's Landing, Slave River, Alberta, June 5, 1908: 



Rosa acicularis Lindl. Small depauperate form. 

 Prunus corymhulosa Rydb. In good flowers. 



Bear Rock, mouth of Bear River, Fort Norman, Mackenzie, 

 July 9, 1908: 



Cypripedium passerinum Richardson (?). Only in leaf, and the 

 ' species doubtful. 



Mouth of Kogaryuak River, 18 miles east of Coppermine 

 River, Coronation Gulf, Arctic coast, Canada, June 18, 191 1: 



Salix arctica Pallas. Rather small specimen. 



Draba hirta L. Tall specimen. 



Astragalus sp. An unknown species, somewhat resembling A. 

 alpinus, but more slender, with small, narrow, grayish, hirsute 

 leaflets, white flowers, purple only on the tip of the keel, 

 black-hairy calyx shorter than in A. alpinus. No fruit was 

 found, which makes it impossible to characterize the plant 

 fully. 



Lupinus arcticus S. Wats. A form more grayish-pubescent than 

 the Victoria Island specimen. 



Hedysarum Mackenzii Richards. A low specimen. 



Rhododendron lapponicum L. 



Cassiope tetragona D. Don. Luxuriant specimens. Used as fuel 



by the Esquimeaux.
