216 HEPATIC M. [_Anthoceros. 



bling the young germen of a Jungermannia, Again, and much 

 more rarely, we have found one of these pistilliform bodies 

 enlarged into a perfectly sphaerical form, tipped with a short, 

 slender style, the whole not larger than an eighth of the calyx ; 

 the contents of so small a body we could not satisfactorily ascer- 

 tain, but they appeared, when pressed out, to consist of a pulpy 

 substance. 



We can state nothing more respecting the fructification, from 

 our own observation. Micheli informs us, that the calyces 

 contain a single sphserical capsule, filled with seeds, but desti- 

 tute of filaments. Smith has figured a similar large sphserical 

 body at the bottom of the calyx, but has not noticed its con- 

 tents. Now, if these capsules were similar to those of Riccia 

 crystallina, that is to say, if the seeds were covered with a 

 single membrane, we presume the style or mucro which we 

 have seen in the young state of the fructification, would be 

 apparent in the more perfect fruit; yet neither Micheli nor 

 Smith have represented it. 



III. ANTHOCEROS. 



Capsule pedunculated, linear, bi-valved, having a central columella, 

 to which the seeds are attached, and arising from a tubular 

 perianth.
