BRYOLOGICAL NOTES 



II. Two Mossics Nicw TO Fria^AM) 



By a. LkRoy Anijkkws 



Present knowledge of the moss-flora of Iceland rests sub- 

 stantially upon the work of Oronlund,* who besides his own 

 collecting was at considerable pains to bring together previous 

 collections and publications and subjected everything to a

 bryologists as Zetterstedt, Berggren, Lindberg and C. Jensen. 

 These lists are supplemented somewhat by notes of Helgi 

 J6nsson contained in oecological papers on the flora of various 

 parts of the island,! his bryophytes also having passed through 

 the hands of C. Jensen. The Botany of Iceland, edited by 

 Rosenvinge and Warming, of which two parts have already 

 appeared,! promises soon a part on the bryophytes by A. 

 Hesselbo. My own collections were made in the summer of 

 1914. I have already! called attention to an hepatic not hitherto 

 known from the island. The two following mosses are likewise 

 additions, I trust of sufficient interest to justify this note. 



Dicranum Anderssonii (Wich.) Schimp. This species was first 

 recognized by Wichura among his collections from Lapland 

 (Swedish) in 1859II and is distinguished from its nearest relatives, 

 D. fulvellum and D. hyperhoreum, and for that matter from all 

 other northern Dicrana by its very short seta, the capsule not
