HAB. Woods and shaded banks in the north of England 



and Ireland. Not uncommon in Scotland. 

 Whole plant, when growing, of a very yellowisKhue. Stems 

 simple, about an inch high. Leaves of a lurid green, especially 

 if dry; when seen under a microscope the margin and 

 nerve are of a deep blood colour, and the veil is of a red or 

 orange hue, which renders the moss very discernible at first 

 sight. 



We are indebted for many important remarks relative to the 

 serpyllifolia tribe of the Brya to our kind friend the Rev. Mr. 

 Dalton, as well as for excellent specimens of all the species.
