290 PLANT LIFE OF ALABAMA. 



Alabama, the Raccoon Mountains in Morgan County, and Lookout 

 Mountain in Dekalb County. The writer communicated his collection 

 made in southern Alabama, 1868 to 1878, to the authors of the Manual 

 of the Mosses of North America, and also to C. F. Austin and to Dr. 

 Karl Mueller in Halle, the latter describing Hypnum homalostcgiuni ' as 

 a new species. His collections made subsequently in different parts of 

 the State were submitted to Mr. Holzinger and Mrs. Elizabeth G. Britton 

 for identification. To the peat mosses special attention was given 

 in the attempt to contribute to the Sphagna exsiccata to be issued 

 by Professor Eaton and Mr. Faxon. Most of the specimens of this 

 difficult genus were placed in the hands of Professor Warnstorf for 

 identification, who found two species among them not described 

 before Sphagnum mohrii and Sphagnum mobiliense? To Mrs. Britton 

 thanks are due for the examination of the species of Bruchia and many 

 others and for the revision of the catalogue of Alabama mosses. The 

 collections made recently by the Biological Survey of Alabama in the 

 vicinity of Auburn have added to our knowledge of the distribution of 

 mosses in the "State. 



To obtain data for the exhibition of the geographic distribution 

 of the mosses known from Alabama, the following authorities were 

 consulted : 



Bridel, Bryologia Universa, 1826-27. 



Hornschuh & Sturm, Bryologia Germanica, 1823-1825. 



Hornschuh, Musci, in Martins' Flora Brasiliana. 



Mueller, Karl, Synopsis Muscorum Frondosorum, Halle, 1851-1853. 



Sullivant, W. S., Musci and Hepaticae of the U. S. in Gray, Man. 1856. 



Sullivant & Lesquereux, Musci Boreali-Americani. 1865.

Lesquereux & James, Manual of the Mosses of North America, 1884. 



Macoun & Kindberg, Catalogue of Canadian Plants, Part 6. 1872. 



Besides these, use has been made of the papers on mosses published 

 by Various authors in the contributions of the department of botany, 

 Columbia University, in the Botanical Studies of Minnesota, Vol. 1, 

 and in the botanical reports and floras of New Jersey, New York, 

 West Virginia, Ohio, Illinois, and Nebraska. 



In the arrangement of the families, genera, and species, Lesquereux 

 & James's Manual has been mainly followed. 



GENERAL DISTRIBUTION. 



At present 153 species and 13 varieties with 4 sub varieties or forms 

 of Musci are known from Alabama. Of these, 112 species, or 70 per cent,
