The Mosses of Monroe County. 



By F. L. riCKETT AND MlLDK!.!) NOTIIXAOKT.. 



The nuly lists of IndiiUia nujsses the writer has been abh> to find are 

 as follows : A list of (i!) species reported from Jefferson County by A. H. 

 Yoniin in ls7(i, and published in tlie I'otauical (lazette of that date; a list 

 of 13 species reported Iiy W. S. Blatchley in March, 1887, and included in 

 a thesis listin.i-- tlie plants of 3Ionroe County under tiiat date; a list of 49 

 si)ecies reported by L. M. Fnderwood in the I'roc. Ind. Acad. Sci. for 1803; 

 a list of 9 species reported by Guy Wilson from Hamilton County in the 

 I'roc. Ind. Acad. Sci. for 1894. Because of tlie meagerness of some of 

 these li.sts and the changes iu classification resulting from careful study 

 of mosses sinc.,» the publication of the first of these lists, there seems to be 

 room for a new check list of Indiana mosses. As a beginning of such a 

 list the i)resent report is presented. 



E.-irly in 1911 a small collection of mosses maturing their spores in 

 spring and early summer was made. A fuller collection of forms fruiting 

 in fall and early winter was made in 1912. The material of this later 

 collection has been carefully identified, and that of the earlier collection 

 reindentified, altogether making a list of ."il species and 3 varieties from 34 

 genera and 12 families. With the exceiition of forms easily determined, 

 only fruiting forms have been considered. The list as given includes but 

 five sterile forms. 



In every case herbarium preparations have been made. These are of 

 two kinds. Fresh .specimens of individual plants and of small typical 

 groups were taken from a moist chamber and quickly dried under a pres- 

 sure of 100 iinunds to I.IO pounds and then glued to cards for preservation 

 in enveloi)es on herbarium sheets. Other specimens were allowed to dry 

 without pressure in mats (jr tufts as they grew, and then kept in card- 

 board trays. The latter specimens are of special value as material for 

 future comjiarison and to show the habit of the dried plants. Notes of 

 time and place of collection, of substrata, appearance of the sporophyte at 

 the time of collection, appearance of plants under normal conditions, and 

 any peculiarities due to season and variation from type are recorded. 

 Important observations touching these points are given under each species
