Color of leaves 



The color of the leaves of most mosses varies from light 



or yellowish-green to dark green. 

 Leaves usually conspicuously light or yellowish-green 



24, 25, 31, 34. 



Leaves glaucous or whitish green especially when dry 



.... 9. See also Sphagnum (p. 73). 

 Leaves bluish-green .... 3, 41. 

 Leaves usually conspicuously dark or olive-green .... 



19, 20, 21, 22, 28, 36, 38. 

 Leaves sometimes with a reddish tinge .... 39. See also 



Sphagnum (p. 73). 



Color of seta 



The seta of most mosses is reddish-brown. 

 Seta yellowish .... i, 2, 6, 8, 24, 25, 30. 

 Seta dark red .... 4, 27, 41. 



Setae clustered .... 8, 29, 30, 39. 

 Most mosses have a single seta. 



Seta very short or apparently absent, so that the capsule is 

 partially concealed by surrounding leaves 19, 22, 36. 



Position of capsule 



Capsule erect 2, 6, 8, 10, 20, 22, 23, 24, 38, 39, 40, 41. 



Capsule inclined (between erect and horizontal) ....

Capsule horizontal .... 27, 28, 29, 30, 35, 41. 



Capsule hanging down .... 25, 26, 27, 28, 29, 30, 41. 

 25 and 27 are especially conspicuous in the spring 

 and early summer on account of the capsules being 

 thickly crowded together; they are bright green at first 

 and then change to brown. 



Capsule partly concealed by leaves .... 19, 22.
