90 HISTORY OP BRITISH MOSSES. 



Zygodon, i. e. the absence of tbe peristome. Mr. Wilson, 

 a deservedly trustworthy authority, has indeed found spe- 

 cimens of this plant in a locality in Wales, in which there 

 are distinct traces of a peristome : his interesting account 

 will be found in the description of the species. Midler 

 enumerates four varieties of tliis species. — Engl. Fl. jp, 11. 

 Mail. Sijn.pt. 1.^. 660. 



17. Hymenostomum (Gymnostomum) phascoides, Wil- 

 son. — Weissia phascoides, Synop. Muse. Fr. ii, 634. 



Lower cauline leaves lanceolate and linear-lanceolate, 

 upper ones crowded into a squarrose tuft, linear-lanceolate, 

 very long and flexuose, with the midrib running out into a 

 point, both surfaces from the middle to the point minutely 

 papillose; several setae from the same branch; capsule 

 erect or oblique, as short again as the perichsetial leaves, 

 subspherical, ovate or elhptical ; lid couvexo-coiucal, shortly 

 rostellate, subpersistent. 



Found in damp sandy and clayey soil, near Mere in 

 Cheshire, by Mr. Wilson, and also by Mr. Mitten in 1847, 

 at the margin of a drained fishpond near Hurstpierpoint in 

 Sussex. Nearly allied to the H. squarrosum, a rare Conti- 

 nental species.
