BMTISH MOSSES. 



From Hobkirk's " Synopsis " we have extracted two or three 

 descriptions of recently discovered species, which may be of ser- 

 vice as indicating the character of that work, and its claims upon 

 all students of British Bryology. 



Baxtramia (Philonotis) adpressa. Ferg.— Plant widely ceespitose, 

 erect, 2-3 in. either dull, glaucous green or reddish ; leaves papil- 

 lose, erect when moist, with one wide plica on each side of nerve, 

 incurved towards apex, slightly twisted when dry, widely ovate from 

 an amplexical base, not acuminate, apex either obtuse or cucullate, 

 with a very slight mucro, or in the slender forms rather acute, 

 margin denticulate, slightly reflexed ; nerve very thick, continuous; 

 areolae small, ovoid above, shorter and wider towards the base. G. E.
