This plant in the curious structure of the perichetium will rank 
with Tortula convoluta, revoluta, and T. pilifera of this work 
(Tax. XII.), differing from all in its flexuose fruitstalks, and their 
great length. The operculum and the peristomium too are re- 
markably long, as well as the perichetial leaves.
