and moistened by the hot vapor from the fumaroli or smoke holes of semi- 

 extinct volcanoes. 



The story of our Portuguese plant points to the value and necessity of that 

 interchange of ideas between the bryologists of the two continents which the 

 "Bryologist" under Mrs. Smith's able management has done so much to pro- 

 mote. 



If Dr. Best's identification of C. Whippleanum and C. leuconeurum with 

 one another and with our Portuguese plant stands, as I certainly think will 

 prove to be the case, the synonymy of the plant would seem to be as follows: 

 that of the American plants has been taken from Dr. Best's Revision of the 

 Claopodiums (loc. cit.).

NOTES ON LEPIDOZIA SETACEA 

 E. J. Hill 



In the summer of 1907 I collected this scale moss in Bergen swamp, Genesee 

 County, N. Y. A bed of Sphagnum was seen to be mixed with hepatics, and a 

 packet of it was taken. When examined some time afterward three were found 

 associated with the Sphagnum acutifolium, which formed the bulk of the packet. 

 They were Mylia anomala (Hook.) S, F. Gray, Lepidozia setacea (,Web.) Mitt, 

 and a Cephalozia which in its leaf characters answered very well to C. connivens 

 (Dicks.) Lindb., all of which are known to grow in Sphagnum. As all were 

 without fruit the determination had to be based on other characters. L. setacea 

 being new to me, and either rare or seldom detected, and liable to be confused 

 with the more common L. sylvatica Evans, some was sent to Dr. Evans, who con- 

 firmed the identification. Thus another station for this species is added to the 

 few that are definitely known in our flora. It has five in New England: Beth- 

 any, Conn.; Woods Holl, Mass.; Lonesome Lake in the Franconia Mountains, 

 N. H.; Waterville, N. H.; and Mt. Desert, Me. 



The flagella which spring from the axils of the ventral leaves of L. setacea 

 were well supplied with rhizoids. These have a globose enlargement at the 

 distal end by means of which it clings to the mosses among which it grows. 

 They sometimes adhere so firmly that the fragile stems are broken in efforts 

 to detach them. (See Warnstorf , Kryptogamenfl. der Mark Brandenburg 1 : 

 257. 1902.) I found similar spheroidal expansions of the ends of some of 

 the rhizoids of the Cephalozia. They were not as abundant as on the stems of 

 the Lepidozia, but to all appearance serving the same purpose. Contact with
