ON HEPATICAE. 



297 



So much so, that in my opinion the family is not admissible into 

 the group Hepaticae. So far as my observations go, there is 

 nothing analogous to the pistillum, but the capsule is developed 

 at first at a considerable depth within the substance of the 

 frond, and it is the cellular substance between it and the sur- 

 face that becomes dislodged, and which is called by botanists 

 the Calyptra. My observations go to shew that over the sur- 

 face corresponding to the situation of the nascent capsule, 

 there is a funnel shaped filament, the narrow end of which pe- 

 netrates some distance into the substance of the frond : this I 

 take to be the manner of action of the male influence. The 

 great development of the anthers, their obvious dehiscence, 

 and the free communication they have outwardly by means of 

 the large aperture of the chambers, connected with the ab- 

 sence of a pistillum, and the correspondence again of the ap- 

 pearance of the young capsules, with the brown filament just 

 mentioned, appear to me worthy of attention. 



The following list of Affghan Hepaticae is sometimes re- 

 ferred to.

in fructification.
