Askrigg Common.

 a stone by the side of the path. I make it Ditrichnni flexicaule 

 Hpe. var. densnm Braithw. var. hrevifoliiun Kindb. In addition 

 to its short leaves it has very small, dot-like and crowded cells, 

 distinct from type. It is described by Macoun in 'Canadian 

 Mosses ' as a sub-species, with the remark, ' perhaps a distinct 

 and proper species ; the tufts are quite barren.' So distinct was 

 the moss in situ that I gathered it for a Campylopus, although 

 I have seen Ditrichnni flexicaule in many places in Yorkshire 

 and Durham. Unfortunately the plant is quite barren, as the 

 Canadian one mentioned above. I intend to get further opinion 

 on this plant. 



Growing with the Ditrichnni was the hepatic Scapania aspera 

 Bernet, and on the moor close by are Hypnum inter^nedium Ldb. 

 and H. fluitans V2^x. Jeanhernati Ren. forma tenella Ren.
