Collection of Arctic Plants. 3jg 



an elevation of 10,000 feet above the level of the ocean, near 

 the limit of perpetual snow. The author however observes, 

 that the species found there differs somewhat from ours, in 

 having the flowers uniformly diandrous and the leaves not 

 emarginate. 



25. Polygonum. 



43. P. viviparum. 



This, like the last plant, is of common occurrence in the 

 north of Europe, of Asia and America, particularly the arctic 

 districts. In the alps of the south of Europe it also appears, 

 but always growing at a great elevation above the level of 

 the sea. 



Besides being common in Arctic America, it is found in La- 

 brador and Canada ; and my friend Mr. Boott has gathered it 

 upon the summit of the White Mountains. 



26. KoNIGIA. 



44. K. Islandica. 



Found in Iceland (as its specific name implies) ; also in the 

 Faroe Islands and Greenland ; and, as far as my knowledge 

 goes, no where else. 



AMENTJCEjE. 



27. Salix. 



45. S. arctica. Br. 



First discovered in Baffin's Bay, during Captain Ross's 

 voyage ; afterwards in Greenland, Melville Island, and Igloo- 

 lik ; thus well deserving of the appellation which Mr. Brown 

 has applied to it.
