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 OC. F. Austin and to Dr. 
Karl Mueller in Halle, the latter describing Hypnum homalostegium' 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 Martius’ Flora Brasiliana. 
Mueller, Karl, Synopsis Muscorum Frondosorum, Halle, 1851-1853. 
Sallivant, W.S., Musci and Hepaticae of the U.S.in Gray, Man. 1856. 
Sullivant & Lesquereux, Musci Boreali-Americani. 1865. 
Austin, C. F., Musci Appalachiani, list of labels, 1870. 
Bescherelle, E., Prodromus Bryologiae Mexicanae. 1871. 
Sullivant, W.S., Icones. 1865-1875. 
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 subvarieties or forms 
of Musci are known from Alabama. Of these, 112 species, or 70 per cent,
