This plant in the curious structure of the perichztium will rank 
vith Tortula convoluta, revoluta, and T. pilifera of this work 
(Tas. XI.) , differing from all in its flexuose fruitstalks, and their 
great length. The operculum and the peristomium too are re- 
maikably long, as well as the pericheetial leaves.
