178 HISTOEY OP BEITISH MOSSES. 



loosely imbricated, lanceolate^ with reflexed margin, carinate ; 

 capsule oblongo-pyriform, broadly striate, brownish-yellow ; 

 calyptra campanulate, slightly pilose ; teeth of the peristome 

 eight, bigeminate. — Ilornsch. ined. ; Br'ul. Bryol. Univ. v. 1. 

 p. 789; Milll. Sijn.pt. \.p. G97.

6. Orthoteichum eupimcola, Funck. {RocJc Bristle 

 Moss.) Stems erect or procumbent; leaves suberect, 

 straight, rigid, broadly lanceolate ; capsule furrowed above ; 

 teeth sixteen, patent; calyptra very hairy. — Bnj. Fl. j). 54. 

 Orthotrichum rupestre, Miill. Sjn.pt. I. p. 707. 



On rocks and stones on the mountains. Fr. June. This 

 species is very rigid in habit, with some of the general cha- 

 racter of 0. affme, but affecting quite a different habitat.
