HAB. On moist banks. 



We have noticed above that this species can scarcely be 

 distinguished from D. falcatum and D. Starkii, but by the 

 absence of a struma at the base of the capsule. 



26. D. subulatum ; stems branched, leaves from a broad sheathing 

 base subulato-setaceous secund entire, capsule ovate sub- 

 cernuous, lid with a long beak. (TAB. XVIII.)

HAB. Moist banks. About Forfar, Scotland. Highland 



mountains, not unfrequent. Mr. Drummond. 

 Mohr united this species with the preceding one, and 

 we must confess that we can perceive no other differences 

 than those mentioned in our specific characters. 



27. D.fulvellum ; stems rather short thickly tufted simple, leaves 



subulato-setaceous scarcely secund those of the perichsetium 

 convolute, fruitstalk scarcely longer than the leaves, capsule 

 erect turbinate sulcated when old, lid conico -rostrate. ( SUPPL.
