HAB. On walls and rocks. 



Nearly allied to this is the Trichostomum funale of Schwae- 

 grichen, which we have in this work ventured to make a variety 

 of Tr. patens ; but our Gr. pulvinata is a much smaller plant, 

 having broader leaves much more suddenly acuminate. The teeth 

 of the peristome are generally perforate or deeply cleft, more 

 rarely entire ; hence it has by some writers been put among the 

 Dicrana, and by others among the Trichostoma. It is quite 

 unnaturally arranged by some authors in the genus Dicranum. 

 5. Gr. trichophylla ; stems elongated loosely tufted, leaves lax 

 waved lanceolate carinate gradually tapering into a diaphan- 

 ous point their margins recurved, fruitstalk flexuose and 

 curved, capsule elliptical-ovate sulcate, lid rostrate. ( SUPPL.

HAB. Discovered in Scotland by Dr. Greville on stone

 found to be not uncommon ; as upon Arthur's seat, and 

 on the coast of Fife ; Ravelrig Toll. Plentiful in the
