 erect, often fascicled ; leaves from a broad sheathing base, broadly 

 lanceolate, acute, concave, much recurved, and directed to every 

 side, crisped when dry; "capsule ovate, subcernuous; lid rostrate."

 lanceolate, somewhat undulate, nerved throughout, the upper 

 half toothed ; fruitstalks not 1 inch ; capsule ovate, subcernuous ; 

 lid rostrate. 



Hab. On stones at the sides of burns, in shaded sandy 

 places, plentiful. Spring. 7/ 



9. D. polycarpum, stems tufted, rather short ; leaves linear-lan- 

 ceolate, concave, entire, crisped when dry ; fruitstalks i ; capsule 

 ovate, erect, or slightly inclined ; lid half as long as the capsule, 

 pointed, inclined. 



Hab. On rocks, in light green tufts. Humbledon Dean,

10. D. bryoides, stem simple; leaves elliptic-lanceolate, entire, 

 bifarious, the parichaetial ones like those of the stem ; fruitstalks 

 terminal ; capsule erect ; lid conical, acuminate.
