Which of these species may be found in the Faeroes is not 

 easy to decide (cf. also Borgesen, 12, p. 795). But it does not 

 appear altogether improbable that 19 species (marked with a f 

 before the name) could occur there. 



The 51 Faeroese species which are not found in Iceland are 



the following: —

Possibly many of these species, perhaps almost half of them, 

 are to be found in S. and SW. Iceland. The 26 species marked with 

 a | before the name may possibly be found in Iceland, though 

 with many of them this is doubtful. 



If it should appear from further investigations that some of the 

 species considered not common to the Faeroes and Iceland are com- 

 mon to them, it should not be assumed from this that the floristic
