APPENDIX 



HELPS TO IDENTIFICATION OF THE MOST 

 COMMON AND CONSPICUOUS MOSSES 



Note. Only the conspicuous characteristics are given here. These may 

 vary at different seasons of the year. 



A. Fruit at the apex of the stem or of a well-developed 

 branch, sometimes appearing lateral by the new growth 

 of the plant. Stems generally erect, and often not 

 branched; or, if slightly branched by forking, usually 

 wath not more than two or three branches. ^ Acrocar- 

 pous Mosses, p. 77. 



B. Fruit on the side of the stem or on a very short lateral 

 branch. Stems prostrate or ascending, rarely erect, 

 usually much branched (with more than two or three 

 branches).^ Pleurocarpous Mosses, p. 172. 



A (Acrocarpous Mosses) 



Manner of growth 



Individual plants of the acrocarpous mosses can nearly 

 always be easily separated, as the stems are erect and 

 do not interweave. In some cases the stems are matted 

 together below with a felt-like mass of radicles, called 

 tomentum. 

 Stems of most acrocarpous mosses are erect, and often not 

 branched; or if slightly branched by forking, usually with 

 not more than two or three branches. ^
