NOTES ON RARE AND LITTLE KNOWN MOSSES. 



Bryum proligerum (Lindb.) Kindberg. Br. Eu. & N. 

 Am. 2:384. 1897. 



IVebera proligera (Lindb.) Kindb. Enum. Bryin, Dov- 

 rens. App. no. 309. 1888. 



This species has been included with IVebera annotina 

 Schwagr. by American authors and is still described with 

 that species by Dixon in his Handbook of British Mosses. 

 The " crowded, green, foliaceous, 2-3 pointed gemmae," be- 

 long to B. proligerum. The several varieties and the 

 foot-note indicate that British specimens still require more 

 study. Although this species was fully described and con- 

 trasted with W. annotina \>y Limpricht in his Laubmoose, 

 it was not until Correns figured and described it, that 

 it began to be known in America. Neither Macoun's Cata- 

 logue nor Kindberg's Enumeration record it for North 

 Br-^ proi.g.ru». America, and Prof. Holzinger's note in The Bryologist and 

 Mr. Huntington's in Rhodora give the only two published stations. This 

 year I have found it at two widely separated localities in the Catskill 

 and Adirondack Mountains of New Vork; it was fruiting at both sta- 

 tions. At Woodland Valley, near Phoenicia, it grew on the margin of a 

 spring, while at Chilson Lake, Essex Co., it grew on wet crumbling road- 

 side banks. Even with a low magnification the characteristic gemmae may 

 be recognized, and they are formed from April to November. The accompany- 

 ing illustrations were made from fresh specimens on June ist; they show the 

 three and four pointed apex, and one shows three rudimentary rhizoids. 

 They are magnified 120 times. A study of the material in our herbar- 

 ium shows the following stations and distribution: 



Stations — White Mountains. N. H., Oakes; James, 1866; Closter, N. J., 

 Austin, 1866-1879; Charleston, S. C, J. D. Smith; Sand Lake, N. Y., Peck, 

 1864; Minnesota, Holzinger, 1897; Massachusetts, J. W. Huntington, 1900; 

 Mt. Washington, Mass., Aug. Catskill Mountains and Adirondack Moun- 

 tains, E. G. Britton, 1901 ; Vancouver Island, Macoun, 1875. The stations 

 recorded in Macoun's Catalogue for W". annotina doubtless include several 

 referable to this species.

Sei.igeria Doniana (Sm.) CM. 



This moss stands in the manual as A nodus Donianus Br. & Sch., and 

 was originally described as Gymnostonum Donianus Smith, because it has no 

 peristome But with this exception, this species is hardly distinguish- 

 able from Seligeria pusilla (Ehrh.) Br. & Sch.. near which all recent authors
