HAB. On the lower part of the trunk of a Beech-tree at 



Fotheringham, four miles south of Forfar, Scotland. 



Very rare, only a small patch found in fructification. 



Mr. Drummond. 



This moss is not uncommon in Switzerland, where we have 

 gathered it abundantly, and whence Dillenius received it ; but 

 in Britain it was unknown till lately, when it was found by 

 Mr. Drulfhmond, though only in one spot, and there very 

 sparingly. It is intermediate, as to size, between N. pumila, 

 and N. crispa, and may, besides, be readily distinguished from 

 both those species by the different form of its leaves and im- 

 mersed capsule. 



3. N. crispa ; leaves bifarious oblong acuminulate transversely ru- 

 gose, fruitstalk much exserted, capsule ovate. (TAB. XXII.)

HAB. On trees and rocks in subalpine countries, especially 



in a calcareous soil. 



Scarcely any moss can exceed the present in beauty. Its 

 size, being often from six to eight inches in length, its regularly 

 pinnated branches, its large, shining, and crisped leaves, give it 

 more the appearance of some of the fine tropical mosses, than 

 of those of our own country, where it is far from uncommon in 

 the mountainous districts, and frequently covers a great extent 

 of surface upon the trunks of old forest-trees. In this, as well 

 as the preceding species, the extremity of the leaves is, under a 

 magnifying power, slightly serrated. The present has the 

 fruitstalks much exserted, in which it differs strikingly from N. 

 pumila, as well as from N. pennata ; and the capsule is ovate, 

 approaching to spherical.
