HAB. a. and /3. not uncommon in the mountainous parts of 

 England, Scotland, and Ireland, upon rocks, particularly 

 near waterfalls. 



In our former edition of this work we were induced to unite 

 the present with the following species. But we have since had 

 the opportunity of seeing the latter, which we then knew but 

 imperfectly, in great abundance upon the mountains, and we 

 are disposed to agree with our friend Dr. Greville in consider- 

 ing it a distinct species, depending for its most essential charac- 

 ter upon the distinctly sulcated capsule, and the nature of the 

 cilice of the calyptra. In E. ciliata, these ciliae, or teeth, are 

 of a nature as thick as the calyptra itself, and apparently 

 set on to it with a margin, thus not appearing to be a continua- 

 tion of the calyptra. In E. rhaptocarpa the ciliae seem rather 

 to be the torn or lacerated margin of the calyptra itself, more 

 thin and membranaceous than the rest of the calyptra, and 

 hence more easily broken off; so that the fringe often appears 

 wanting, and is generally so figured. 



4. E. rhaptocarpa ; stems more or less elongated, leaves oblong 

 apiculate, the points of the same colour, capsule cylindrical 

 sulcated, calyptra ciliated at the margin, ciliae deciduous.

 HAB. Ben Bulben in Ireland, J. T. Mackay, Esq. On 

 the higher of the Scotch mountains, perhaps not un- 

 common. On the Breadalbane mountains, near the 

 summits, plentiful. 



Dr. Greville has well illustrated this plant in his beautiful 

 Scottish Cryptogamic Flora.
