Motes on the Tegetation of the North-Fri- 

 sian Islands and a contribution to an 

 eventuel flora of these islands. 



By 



C. Raunkiær. 



•Whereas the vegetation of both the West-*) and the 

 lEast-**) Frisian Islands is described in various excellent bo- 

 tanical works, we are still without a complete work on 

 the vegetation of "the North-Frisian Islands, and the absence 

 of this work is not corrected by one upon the general flora 

 '^of Sleswic Holstein, because in such a work proper allow- 

 .'ance cannot loe nrade for the situation of these islands 

 -•as part of a very peculiar and interesting coast. The ve- 

 getation of the Frisian Islands altogether is not very remark- 

 .able if looked upon simple as a link of the flora of the 

 ■adjacent mainland, ^but studying the coast from Skallingen 

 "to .Helder and duly considering its origin and history and 

 the greät alterations it has undergone in the present geolo- 

 :gical period, we shall be able correctly to understand the 

 .special character of the flora of the Frisian Islands. I hope 

 on a subsequent occasion to refer more extensively to this 

 question making only a few remarks here upon the vegeta- 

 tion of the North-Frisian Islands and giving a list of the 

 botanical results of a joTirney to the islands Amrum, Føhr, 

 Sylt and Romø in the summer of 1887. The hst contains
