When it is considered how extremely common most of these 

 plants are throughout Europe and Northern Asia, and that some 

 of them inhabit also N. W. America, their absence in Eastern 

 America is even more remarkable than their presence in 

 Greenland. 



A small colony of Greenland plants has been found by Mr. 

 Taylor in Cumberland Gulf, on the West side of Baffin's Bay, 

 where the following Arctic Greenland plants occur, viz. : — 



Arabis alpina. 

 Gnaphalium sylvaticum. 

 Cassiopeia hypnoides. 



Phyllodoce taxifolia. 

 Euphrasia officinalis. 

 Kcenigia Islandica. 

 Luzula spicata. 



Carex Hebonastes. 



vulgaris. 



Agrostis vulgaris. 



Another singular feature of both Arctic and Temperate 

 Greenland is its wanting a vast number of Arctic plants which are 

 European, and found also in America. The following is a list of 

 most of these, excluding about 15, which are water-plants, or 

 species whose range is limited. The letter I. placed before a 

 species signifies that it is Icelandic, and is introduced to 

 show not only how many are absent from this island, but also 

 how many are present. The letter S. indicates that the species is 

 found in the south temperate or antarctic circle. The asterisk (*) 

 indicates that the species is arctic both in East America and 

 Europe : —
