IV. The species of plants found in lat 80°-83°, but which 

 do not occur in Spitsbergen, Melville Island, or Greenland, 

 are Androsace septentrionalis, an Arctic plant and native 

 also of the cold Alpine regions of the New and Old World, 

 but which finds its northern limit elsewhere in 72° on the 

 south shores of the Polar islands opposite the American 

 coast ; and Pedicularis capitata, a beautiful plant confined 

 to Arctic Asia and America, but not hitherto found north of 

 Port Kennedy in lat. 72°. The recurrence and the abun- 

 dance of these two plants in the extreme latitudes visited by 

 the Expedition are very singular facts. To these plants 

 might also be added the Deschampsia ccvspitosa, which, 

 though so common a plant of the Temperate Zone and the 

 Arctic Regions generally, is found nowhere either in Tem- 

 perate or Arctic Greenland, except on its east coast ; a 

 peculiarity which it shares with Ranunculus glacialis, 

 Saxifraga Hirculus, S. hieraci folia, and others, all of 

 which are either unknown in W. Greenland or are very 

 rare there. 



Of seventy-three high Arctic plants — namely, such as 

 reach the north coast of the Spitsbergen Group (lat. 80° to 

 80° 40') — Malmgren cites thirteen as not found elsewhere 

 in those islands ; and of these he remarks that they establish 

 a relationship with the Polar island flora, while the rest
