5(5 DICRANU 



HAB. On wet sides of streams and rivers. 



The more ovate, short, somewhat truncate and decidedly 

 inclined capsules furnish the principal distinction between 

 this plant and D.flavescens. 



16. D. spur mm-, stems elongated; leaves fasciculated, concave, 

 erecto-patent, directed to every side, ovate, the superior 

 ones lanceolate, serrulate; capsule oblong, curved ; lid ro- 

 strate. (TAB. XVII.)

HAB. In bogs; Yorkshire. Mr. Teesdvle. Kinnordy., 

 Scotland. Mr. Lyell; always barren, 



This singular species, somewhat allied to D, scoparium, 

 D. undidatum, and the continental D. Schraderi, differs 

 from them all in the breadth of the leaves, most pf which 

 are ovate, the upper ones being longer and narrower, and 

 serrated at the points. The teeth of the peristome of this 

 as well as some other species of this genus will not always 

 be found to be divided into two segments only ; very fre- 

 quently three divisions are apparent, 



|7. ZX crispum ; stems short ; leaves from a sheathing base se-r 

 taceous, nearly distichous, flexuoso-recurved, crisped when 

 dry; capsule ovate, erect; lid with along beak. (TAB. 

 XVII.)

HAB. On moist banks. 



This species has a strong resemblance to the D. Schre- 

 lerianum of Hedwig, which, however, decidedly differs by 

 its shorter and wider leaves, by its inclined capsule and 

 shorter lid. 



}8. D. Scottianum ; stems branched ; leaves erecto-patent, di- 

 rected to every side, subulate, their margins plane, subser- 

 rated, crisped when dry; capsule ovato-cylindraceous, nearly 

 erect ; lid with a long beak. (TAB. XVIII.)

This plant differs from Hedwig' s D. flagellare princi- 

 pally by the direction of the leaves^ which in the latter are. 

 constantly secund, yet we shall not be surprised if future ob- 

 servations on authentic specimens may prove them to be 

 the same. We can ftn4 D. montanum Hedw. to differ only
