1. F. synanthus. — By this name it is proposed to designate the 

 synoicous species confused in Schimper's ' Synopsis,' ed. 2, p. 113, 

 with Wilson's F. viridulus var. pusillus, Bry. Brit. p. 303, where 

 it is described as monoicous, as are his specimens. The specimens 

 sent to Schimper by Dr. "Wood from Pontefract, like the excellent 

 ones from Saporta, are synoicous. The species is found also in 

 Cheshire and Sussex. The limb is sometimes incomplete or 

 nearly obsolete on the vertical lamina ; in the perichaetal leaves 

 the apex of the horizontal lamina is unequal. In the ' Manual 

 of North- American Mosses,' F. synoicus, Sull., is referred to 

 F. inconstans. 



2. F. betoides of all recent authors, Braithtv. Brit. Moss- 

 Fl. t. x. E. a. — Hypnum bryoides, Linn, et Hedwiy. 



Antheridia enclosed in buds or naked, or even solitary in the 

 leaf-axils of the apical fruiting stems. 



Common in Britain and on the continent, ascending to 0000 

 feet in the Alps ; also in America, whence the specimens have a 

 slightly different appearance; but it is there a greenhouse 

 plant.

Foliage rigid and dense in substance. Pyrenees and Britain,

4. F. impae. — Similar to small F. bryoides ; but with more 

 oblong leaves, having shorter and wider points, the inferior 

 edge of the vertical lamina not continued to the base, mostly
