SOME HEPATIGAE FROM MATINICUS ISLAND, MAINE 



Annie Lorenz ' 



A collection of hepatics from Matinicus Island, Maine, the result of a hasty 

 trip made by Messrs, E. B. Chamberlain and A. H. Norton, August 16-17, 1916, 

 has been kindly communicated to the writer by Mr. Chamberlain for examina- 

 tion. They proved to be of such interest that it was deemed advisable to write 

 them up for The Bryologist. 



Matinicus lies 18 miles out from Rockland and is the largest of a small 

 group of those islands farthest from the Maine coast. For a most interesting 

 description of the island the reader is referred to W. H. McAtee's article in Rho- 

 dora for February, 19 16. From a perusal of this paper, as well as the study of 

 these specimens, the similarity of Matinicus to the small islands off Mt. Desert, 

 as Cranberry and Baker's, is evident, and one gains a most attractive impression 

 of the place. As the writer is at present busy with the revision of the Mt. Desert 

 hepatic list, this collection is peculiarly opportune. 



The 18 packets in the collection contained 21 species, these being either 

 several numbers of the same species, or several species in the same packet. This 

 was particularly the case with the material from "The Heath." (Mt. Desert 

 nomenclature again). These packets were a mixture of Riccardia latifrons 

 Lindb.; Mylia anomala (Hook.) S. F. Gray; Cephalozia connivens (Dicks.) 

 Lindb.; Cephalozia macrostachya Kaal. (especially fine material); Calypogeia 

 sphagnicola (Arn. & Perss.) Warnst. & Loeske, (second station for Maine, see 

 Evans, Rhodora, September, 1919); and Lepidozia seiacea (Web.) Mitt. 



Two species in particular, the writer would be very glad to have on the Mt. 

 Desert list, Calypogeia Neesiana (Massal. & Carest.)C. Miill.and, rather curiously, 

 fine Scapania paludicola Loeske, in a spring-hole, between the dunes and High 

 Head. Everything observed in a suitable station on Baker's Island was plam 

 but good Scapania irrigua (Nees.) Dum. 



Aside from the inhabitants of the sphagum bog, which are the same all over 

 New England, the hepatic flora, Hke that of Mt. Desert, is not particularly arctic, 

 nor even of the sub-alpine character of White Mountain regions like Waterville. 

 It consists chiefly of the usual species that grow everywhere, every one of them 

 being common to Connecticut. 



The November number of The Bryologist was published February 17, 1920.
