HAB. Woods. Rare in fructification; but found most! 

 abundantly in that state by Mr. tlobson near Manchester, j 



The columella is produced, and reaches the top of the! 

 lid, which, when the capsules are ripe, and in a dry state] 

 of the atmosphere, it raises up, turning in a spiral manner,* 

 and thus perhaps permitting the discharge of the seeds. Ill 

 in this state moisture be applied to the mouth of the cap-j 

 sule, the lid on the top of the columella will descend, as this! 

 last performs a spiral volution, and the capsule becomes! 

 completely closed again. The segments of the interior pe-J 

 ristome being cleft at the base has induced Weber and! 

 Mohr to make a distinct genus of it. 



f f Stems lelow leafy. 

 4- Capsules erect. 



28. H. curvatum^ branches fascicled, curved; leaves ovato-el-J 

 liptical, concave, serrated at the points, nerve disappearing 

 beyond the middle j capsule ovate, erect ; lid rostrate!

HAB. On trees and rocks. 



The nerve is, as Mohr has justly observed, sometimes 

 forked. In habit it somewhat resembles the two last, bui 

 is considerably smaller, and the stems are leafy throughout 1

HAB. On trunks of trees and rocks, especially such as ar<| 

 calcareous. 



This can only be confounded with the preceding species I 

 but its more slender habit, its leaves more acuminated, les|j 

 concave, with their shorter nerve, reflexed margins, serrate^ 

 nearly their whole length; will ever keep it distinct^
