Aii elegant and distinct moss. The fimbriae are by 

 no means, as Schwagerichen presumes, the laciniae of the 

 This is only three cleft — the divisions round- 

 The fiimbriae, on the contrary, are long linear Ian- 

 ,u snow white organs, of a very different kind, and 

 in great number, flexuosely proceeding from a white mar- 

 gin! of the receptacle, and sometimes even from the pedun- 

 cle. The dons is very narrow, green, usderneath purple 

 and veined, turning up the margin when dry. 



Mctnark* Imperfect specimens of other hepatics prog- 

 nosticating some new species have been observed by me. 

 Among the rest. Mr. Le Conte found one, probably a very 

 distinct Marchantia, in the mountains. It is however nc 

 cessary to wait till these are found in fructification before 

 they can be determined.

This generic description of Roth suits exactly the cha- 

 i acter of the hepatic below described ; so that it must be 

 considered as belonging to the Genus. But it is certainly 

 a different species, as the Thallus is so greatly different, 

 and from its not agreeing at all with tiie European speci- 

 mens of T. hypophylla in my collection. 



Both Weber and Schwaegerichen cite the T. hyfophtl- 

 la as found in Carolina. I have not met with it, but al- 

 most suspect that they have seen imperfect frondes of 

 Marchantia hirsuta, and taken them for the Targionia. 

 Weber, p. 108. Schwagerichen, p. 35. I have not adopt- 

 ed it as an American species on that account, especially 

 as Muhlenberg does not mention it.
