it does not seem, however, to occur at or near the coast)^ 

 Scandinavia, Iceland, the Færoes and Great Britain, in 

 addition, the species extends over "ein mittel-europäisches 

 Gebirgsareal von den Pyrenäen bis zum Balkan mit Vor- 

 stössen zu den deutschen Mittelgebirgen und zahlreichen 

 Standorten im Vorland" (Schröter). In West Greenland its 

 northern limit is the Ignerit Fjord (Umanak), in East Green- 

 land it does not reach so far as to the region of Scoresby 

 Sound. Kruuse (1905, p. 177) states that the northern 

 limit there is at 68° 8' N. lat. 



Habitat. According to Warming in West Greenland 

 it grows in willow-copses and on "herb-flats"; in the most 

 southerly West Greenland Rosen vinge found it in willow 

 and birch copses, on "herb-slopes" and grassy slopes. 



As regards the conditions pertaining to the growth of 

 Bartschia in East Greenland Kruuse (1905, p. 177) writes: 

 "it is very rare north of 66° 20' and only 10 cm. high, but 

 yet it sets flower everywhere and as far as can be judged 

 from the collected material also fruit. It shuns here the 

 coast, and all finding places are well sheltered, exposed to 

 the south and have the character of herby slopes, while the 

 species more to the south prefers heath", and in the Ang- 

 rnagsalik district it is (1906, p. 249) "commonly distributed 

 on herby slopes and in fertile heath". 



Norman records it from Northern Norway as growing 

 "in bogs, on damp cliffs, in birch-woods, on flats at the river- 

 banks and on the beach, as an exception below the upper- 

 most belt of sea-weeds; it occurs chiefly on the sunny sides, 

 somewhat more seldom on the indifferent (eastern and west- 

 ern) sides and as an exception on the shady sides". A. Cleve 

 records that on the mountains in the north of Sweden it is 

 "Ein sparsamer, exclusiver Bewohner der trockenen Blüten- 

 wiese mit vollen S-Exposition . . . Ein typischer hydrophyt
