Cinclidotus.-] APLOPERISTOMI. 51 



HAB. Moist banks, frequently with P. aloides, common. 

 We are quite unable to find any difference between the P. 

 nanum and subrotundum of authors ; and with regard to the 

 species itself, we have seen capsules in so exactly an interme- 

 diate state between it and P. aloides, that we have been at a 

 loss to determine to which they should be referred, and we 

 avow our readiness to subscribe to an opinion that they may be 

 considered mere varieties of the same species. 



XII. CINCLIDOTUS. 



GEN. CHAR. Fruitstalks terminal ; Peristome single, of 32 

 filiform, twisted teeth, anastomosing at their base ; Ca- 

 typtra mitriform. (TAB. I.) 



The catyptrce of all the specimens that we have examined are 

 so far split on one side as to leave some doubt as to the propriety 

 of calling them mitriform, which we do in deference to preceding 

 Botanists. We cannot hesitate, however, to confess, that in the 

 present instance we have but little reliance on the character taken 

 from the calyptra, which, among other tribes of mosses, we have 

 found to be of the greatest importance. The fruit we believe to 

 be terminal, although, in the majority of instances, situated on 

 branches so short as scarcely to leave room for more than perichse- 

 tial leaves. The general appearance of the single known in- 

 dividual of this genus is that of a Triclwstomum, whilst its peri' 

 stome approaches nearer to that of Tortula.
