THE material used for this paper has been entrusted to me for 

 examination by the Botanical Garden, Copenhagen. It embraces 

 in all 438 samples collected by the following: cand. O. Davidsen 

 (O. D.f), Dr. phil. Helgi Jonsson (H. Js.), Professor Chr. Gronlund 

 (Grld.f), Mag. scient. R. Horring (H0r.), Inspector W. Lundbeck (Lb.), 

 Dr. phil. C. H. Ostenfeld (C. H.O.), Dr. phil. O. Paulsen (O. P.) and 

 Adjunkt B. Ssemundsson (B. S.).*) 



Dr. Thoroddsen has given me valuable assistance as regards the 

 spelling of the names of the various localities, and has also shewn 

 me the kindness to go through my list of names, without which 

 my paper, in this respect, would scarcely have been in agreement 

 with his work : The Botany of Iceland I , and for this assistance I 

 tender him my hearty thanks. As regards the habitats given by 

 the various collectors, I have specified these when a form appears 

 in up to 3 samples, by adding the parts of the coast where it has 

 been collected, as well as the name of the finder. In case a form 

 is found in more than 3 samples, the number of samples and the 

 parts of the coast are given only. As to the limitation of the diffe- 

 rent parts of the coast, see Helgi Jonsson, the Botany of Iceland I, 1, 

 page 6, and the map page 7. The samples are, according to the 

 parts of the coast, apportioned as follows: 



South, given in the text as S 58 samples 



South-West ----- S.W 191 



North-West - - - N.W 30 



North - - - N 98 



East - - - E 53

Total 438 samples 



*) The letters in brackets affixed to the names of the collectors indicate 

 the abbreviations of their names, as used in the text; a f signifies, that the person 

 is by now deceased.
