The Root. Some of the Hepaticae seem to be The root, 

 destitute of a root altogether, or are at least not 

 furnished with any conspicuous root, as in Junger- 

 mannla asplenoides ; but where a root is present 

 it consists of a number of small and fibrous pro- 

 ductions, issuing from the base or under surface of 

 the herbage, and fixing it to the soil or substance 

 on which it grows. 



The Herbage. The herbage, in a few species, The herb- 

 consists of a stem furnished with distinct leaves ase<

 formis, and some others, in which the loaves are 

 so distributed as to give the shoot a sort of wing- 

 like appearance. But in the greater number the 

 herbage is frondose, though not upright in its 

 growth like the frond of Ferns (PL VII. Fig. 11.), 

 being seldom furnished with any thing like u stipe ;
