Obs. This plant I never met vrith, hereabouts, until after that portion of the catalogue to which itbelonscs 

 ■was struck off. It grows luxuriantly, in a small patch, on ihe south side of the west branch of Brandy wine! 3 

 few rods above the tork. I found it was known to the neighbors by the name of Breast-treed— thp.v bf ing 

 in the practice of collecting its porous roots, and applying them, bruised, in form of cataplasm, to inflamed 

 breasts. Mr. Elliott notices a similar practice. The leaves have much resemblance to those of Aristo- 

 lochia serpentana,— except that they are larger, and somewhat more cordate. 



Arenaria LATERIFLORA .'p. 54. 1 have recently received, from Dr. Torrey, specimens of Arenaria lat- 

 eriflora, which satisfy me that my friend Mr. Schweinitz was rather hasty in pronouncing upon my plant; 

 I am pretty well convinced it is nothing more than the Stellaria lanceolata, of Torrey. It is remarkable, 

 however, that the slender pedicels are frequently bibractcate, after the manner of Arenaria lateriflora. 



Verbena URTiciEFOLiA. p. 66. By a typographical error, this species is stated to be "noi common." 

 It is very common. 



Carex xanthophysa. p. 98. It is stated in the observation annexed to this species, that the C xan- 

 thophy a, of Muhlenberg, is a distinct plant— being the C striata, of Mr. Schweinitz. In a letter lately 

 j-eceiv from Mr. S. he informs me, that on further examination he has been induced to drop his C striata; 

 believing it, and of course Dr. Muhlenberg's, to be identical with our plant.
