The Curled-leaf Mosses 



The leaves are narrowly lance-shaped from a broad oval base 

 and are usually curled when dry. It is this character which 

 gives them their generic name from oiAcm??, curled. 



The cells are very narrow, coloured and thickened along the 

 median line while the marginal cells below are transparent in 

 several rows.
