 HAB. Rocks ; especially on a calcareous soil. 

 This differs from most of the British species of Tortula by 

 the great length of the stems, and from all by the undulated 

 margins of its leaves when dry. Barbula inclinata of Schwae- 

 , gricheris Suppl. comes very near to this species ; but its stems 

 and leaves are short ; these latter being more erect when moist ; 

 and by its more curved capsule. 



13. T. fallax; stem elongated branched, leaves lanceolate acu- 

 minated carinated patent or recurved the margins reflexed, 

 capsule oblong, lid with a long beak. (TAB. XII.) 

 a. stem about an inch high, leaves recurved.
