The stems in this species are an inch or more in height, 

 much branched. Leaves generally dark green. Capsules 

 nearly immersed in the leaves. The teeth of the peristome, 

 when dry, are erect; when moist they lie flat over the mouth 

 of the capsule, and resemble a horizontal membrane. 



* * Peristome ivlth eight ciliary professes. 



3. 0. crispum ; leaves lanceolato-subulate, much crisped when 



dry; fruitstalks much exserted ; capsule striated ; peristome 

 with eight ciliary processes : calvptra very pilose. (TAB. 

 XXI.)

This can scarcely be confounded with any British species, 

 having striking characters in its large size, very crisped fo- 

 liage, and exserted fruitstalks. It is not so easily distin- 

 guished from the Continental 0. Ludwigii of Schwaegr. 

 Suppl. 9 between which and Hedwig's figure, above quoted, 

 we can perceive no essential difference. With regard to 

 Hedwig's plant, Mohr and Schwaegrichen have already obr 

 served how incorrectly the peristome is represented. We 

 may add, too, that the capsule is equally so ; for with us 

 at least this part, especially when ripe, is evidently striated, 

 as in most of the remaining species of the genus. 



The teeth, though apparently only eight, have each of 

 them a dark line of separation down the middle, and each 

 of these divisions is again marked down their centre with a 

 fainter line. The ciliary processes are always eight, fili- 

 form, jointed. 



4. 0. Hulchinsice ; leaves lanceolate, erect, and nearly straight 



when dry ; fruitstalks much exserted ; capsule striated ; 

 peristome with eight ciliary processes; calyptra very pilose.
