IL New collections belonging to the Botanical Museum at 

 Copenhagen from the second half of the last century made by 

 following travellers: 



1. Professor G. Grönlund, the author of „Islands Flora", 

 travelled in Iceland in 1868 and 1876. He gathered some marine 

 algæ in N. Iceland and SW. Iceland. His plants were determined 

 and published by F. R. Kjellman 1 ). 



2. Dr. L. Kol der up Rosenvinge, who stopped at Rey- 

 kjavik for a few days on his journey to Greenland 1886, gathered 

 some marine algæ. 



3. Mr. Hjalmar Jensen gathered in 1890 few specimens in 

 NW. Iceland and SW. Iceland. 



4. Mr. W. Lundbeck gathered some marine algæ in NW. Ice- 

 land in 1892 and 1893. 



5. Mr. G. H. Ostenfeld, Inspector of the Botanical Museum 

 at Copenhagen, has, as botanist of the Ingolf Expedition (1895 — 96), 

 brought together a large and valuable collection of marine algæ from 

 several places round Iceland. 



6. The author of this paper has in 1894, 1897 and 1898 

 gathered marine algæ in many places round Iceland. 



7. Mr. Ölafur Daviösson has in 1897 and 1898 gathered 

 many specimens in N. Iceland (Eyjafjöröur and Grimsey).

 Mr. C. Hansen, Mr. R. Hørring, Mr. A. G. Johansen and 

 Mr. G uö m un dur Guömundsson have gathered some few 

 specimens at the Icelandic coasts. 



III. Mr. H. F. G. Strømfelt travelled in Iceland in 1883 and 

 brought together a large collection, now to be found in the Riks- 

 museum at Stockholm. I have been able to use this collection, as 

 by the kindness of the authorities of the Riksmuseum it has been 

 lent to me here at Copenhagen. 



Of the collections mentioned Mr. Ostenfelds, my own and 

 Mr. Strømfelts are the most valuable and this paper is chiefly 

 based upon them. 



I have made references to the book of Strömfeit and the
