Hypnace^.] 5 [Thiidium. 



papillose, inner erect, lanceolate, irregularly plicate, suddenly narrowed 



into a long serrulate subula, the margin with a few simple or rarely 



branched, erect nearly smooth cilia. Capsule on a smooth red seta, 



curved, longish cylindric, rufous ; lid conic with an oblique beak ; 



annulus of 2 rows of narrow cells. Peristome yellow-brown, endostome 



yellow with 3 cilia. 



Hab. — Damp woods, very rare. Fr. 10. 



Tyn-y-groes, N. Wales, c. fr. (Holt Dec, 1885) ! ! Lodore, c. fr. (Binsiead Dec, i88g) ! 

 growing intermixed with T. tamariscifolium. 



This plant has now been found in various parts of France, Switzerland, 

 Austria, Germany and Scandinavia ; and indeed was found first in Germany 

 by Roth in 1798. Its identity was first determined by Lindberg on male 

 specimens collected in the island of Hogland. In America it takes the place 

 of our T. tamariscifoHwn.

Dioicous ; stem trailing, bipinnate. Cauline leaves widely cordato- 

 triangular, acuminate, densely papillose at back. Perich. bracts not 

 ciliate. Apex of ramuline leaves broadly emarginate, the terminal cell
