60 MUSCI-ACROCARPI-PERISTOMI. \Bryum. 



cave, of a thin texture with a strong nerve disappearing below the sum- 

 mit. Capsule oblong, approaching to oval, slightly contracted at the

 Funck, and with the figure in Schwaegrichen. 



11. B. argenteum, Linn, {silvery Thread-Moss); stems 

 branched, leaves closely imbricated broadly ovate suddenly and 

 sharply acuminated sub serrulate very concave, the nerve dis-

On the ground, and on walls and roofs of houses, very common. Fr. 

 March.— This plant has, as its name implies, a very silvery hue, the 

 upper portion of the leaves being scariose and white, while the lower 

 part is green. The acuminated points, especially when dry, are patent 

 and resemble hairs. 



12. B. Zierii, Dicks. (Zierian Thread-Moss); stems branched, 

 leaves closely imbricated more or less broadly ovate acuminate 

 very concave reticulated entire, nerve running nearly to the 

 point, capsule clavate cernuous. Dichs. Or. Fasc. 1. t. 4. f.

Rocks, especially of sandstone. Not unfrequent on garden-pots, 

 especially in stoves and green-houses. Fr. June. — This differs from all 

 other Brya in the remarkable shape of its leaves, which are almost wholly 

 composed of nerve, except at the base, and there deeply serrated. The 

 caj)sides and setce are a bright orange colour when mature. 



14. B. capilldre, Linn, {greater matted Thread-Moss); stems 

 short, leaves obovate twisted when dry entire their nerve pro- 

 duced into a hair-like point, their margins slightly thickened, 

 capsule oblong pendulous. Linn. Sp. PL p. 1586. Turn. Muse.
