years by occasional visitors, e. g. Ostenfeld from his visits to the islands 

 in 1895 — 96 as a member of the Danish Deep-Sea Expedition in 

 the »Ingolf«, and the officers belonging to the Danish General Staff, 

 among whom we may mention Lieut. Lomholt and Lieut. Heiberg- 

 Jiirgensen, a Swedish botanist, H. G. Simmons, also wrote several 

 important papers on the flora and made the first attempt at a 

 description of the algæ- vegetation with regard to its formations. 

 He visited the Færoes in 1895, somewhat later than Borgesen and 

 traversed the islands partly in company with him and partly alone 

 from July 12th to Sept. 13th. He made collections especially of 

 marine algæ. 



I may also mention that the above-named visitors to the is- 

 lands in 1895 — 1900 took photographs of the vegetation and land- 

 scape, and the officers of the General Staff, especially Captain K. Rime- 

 stad, also took a series of excellent photographs of the islands. 



On the basis of this rich material we have thoroughly revised 

 the list of the flora and studied the vegetation of the Færoes. 



The writings of the above-mentioned authors and some others 

 are named in the following list only in so far as they deal with 

 the whole of the flora or the nature of the isles, papers treating 

 of single classes of piants being mentioned under these classes.
