ON TWO REMARKABLE HEPATIC MOSSES. 36l 



On two remark-able Hepatic Mosses found in North 

 Carolina, by L. D. Schweinitz. Read November 

 26, 1822. 



In my specimen of North American Cryptoga- 

 lnous plants, published at Raleigh, N. C. last year, 

 1 have noticed two Hepatics, which appear to de- 

 serve further investigation. One is the Sphaerocar- 

 pus terrestris of Micheli, heretofore found exclusive- 

 ly in Italy and England, greatly differing from others 

 of the family, by its remarkable thallus and fructifi- 

 cation, and still very imperfectly known. The other, 

 altogether new, and no less distinguished, was ar- 

 ranged by me, in the little work just cited, as a se- 

 cond species of Targionia, and named T. orbicularis. 



These two Hepatics, figured in the annexed draw- 

 ing, I shall now endeavour to illustrate, by such ob- 

 servations and descriptions, as an attentive study, un- 

 der the compound microscope, has suggested.
