tantic mosses, hul have mucb fewer Alpine-Arctic than [celand, 

 und somewhat fewer than Norway. In the richness of circumpolar 

 mosses, Ihey come after [celand, bul before Norway and Scotland; 

 and in Ihe Western -Continental mosses, Ihey stand somewhat 

 above [celand, but below Scotland and Norway. They conse- 

 quently bear a closer resemblance to Scotland, a somewhat slighter 

 one to Norway, and a still slighter one to Iceland, but in those 

 points in which they diller from Scotland and Norway they draw 

 near to Iceland. The largest Alpine-Arctic and Subarctic ele- 

 ment is met with in the northern part, where the mounlains are 

 highest. 



With regard to the Freshwater Algæ F. Børgesen comes lo a 

 similar conclusion: — Greatest resemblance to West Europe, espe- 

 cially to Scotland and Ireland ; Arctic stamp most conspicuous on 

 the Nordreoer (p. 200). 



As to the other cryptogams, the conditions are less distinct, 

 probably, chielly because the investigations hitherto made pf the 

 countries in question do not permit of a fully reliable eomparison. 

 With reference to the Freshwater Diatoms, E. Østrup, however, 

 writes as follows (p. 299): — Common with Europe, with Scandi- 

 navia and with Great Britain 73 — 83%; with Riesengebirge and 

 with Greenland 34%; with Spit/.bergen 25%, etc. ; and he comes 

 to the conclusion that the Diatom-flora has »a European, especially 

 North European character« 1 . 



Regarding the Fungi, Rostrup comes to the conclusion, that 

 168 species from the Færoes are known at the present time, and 

 of these, 9 species are found in the latter islands only. Of the rest, 

 10 species are found only in the countries north of the Færoes (Ice- 

 land, Greenland, Finmark), while 149 have been met with in Tempe- 

 rate Europe, and are for the most part widely distributed (116 of them 

 occur in Denmark). As only 78 Færoese species have been found 

 in Iceland, the Fungi also point to a relationship with Europe. As 

 at the present time no less than 622 species are known to occur in 

 Greenland 2 , and 542 in Iceland 3 , it seems probable that the know- 

 ledge of the Fungus-flora of the Færoes is as yet rather imperfect. 



1 Even on the basis of his very poor material, N.Wille in 1897 Botaniska 

 Notiser) arrives at the conclusion that the flora should more particularly be 

 characterized as a poorer part of the English flora, and that the forms agree, more- 

 over, very closely with those of England.
