198 HISTORY OF BRITISH MOSSES. 



24. Bryum roseum^ Schreb. [Tlomeeons Thyme Thread 

 Moss.) Leaves spreading, obovato-spathulate, acute, ser- 

 rated, waved; ner^e reaching to the point; capsule ob- 

 longo-ovate, pendulous. — Eng. Fl. p. 63; Mull. Syn.pt. 1. 

 p. 247. 



On grassy banks and heaths, especially sucli as are par- 

 tially shaded; common. Pr, November. Brucli and Schim- 

 per, in speaking of this Moss, describe it as "the largest 

 and most beautiful of all the European species. It is easily 

 known by the shining rosette with which the stem is sur- 

 mounted.^' In Britain the fructification is rare. We have 

 had specimens gathered by the Eev. W. S. Hore, in Devon- 

 port, and the Eev. James Drummond has gathered it 

 sparingly in the west of Scotland, but it is seldom met with 

 in that state. Beautiful specimens in fruit have been sent 

 from North American stations, where it is common. The 

 beautiful horizontal tuft of leaves however makes amends 

 for this want, and a secondary tuft is often protruded from 

 its centre instead of a cluster of fruit-stalks. In habit it is 

 closely allied to the species of which the succeeding section 

 is composed. 



^'^ Leaves with their margins evidently thickened.
