journeys in 1895 — 96 — 97, especially in 1897 when I in company 

 with Mr. Jac. Hartz traversed the islands for six weeks for the 

 purpose of studying the vegetation and making collections. 



In the following treatment I have only numbered those species 

 which I have actually seen and which must be regarded as belonging 

 to the islands, or at least completely naturahzed; a f placed before 

 a species denotes that it has been accidentally introduced. On 

 the other liand 1 have omitted all more or less doubtful state- 

 ments of prcvious authors; as on looking through the older collec- 

 tions, I have arrived at the conclusion that the determinations are 

 at least as often wrong as not, many of Landt's in particular being 

 undoubtedly incorrect, a faet which may be explained by remem- 

 bering that he was not a botanist and that he wrote his Flora 

 after returning to Denmark; as it is, he has mentioned many com- 

 mon Danish piants as belonging to the Færoes, though this is 

 evidently a mistake in the majority of cases. The distribution of 

 the species on the different islands is naturally not fully known, 

 but I have given as many details as possible, based mainly on 

 Rostrup's and my own observations. Wherever possible, I have 

 also given the vertical distribution and the time for flowering and 

 fruiting. 



The discoverer's name is given in brackets after that of the 

 habitat. I have seen specimens from nearly all the habitats (espe- 

 cially Rostrup's).
