 Root perennial, creeping, long. Stem about 2 feet long, branching, procumbent. 

 or twining round other plants, twisted, a little hairy. Leave* an inch to an inch

 rounded. Corolla pale red, or reddish white, about 3 fourths of an inch lonr. 

 Stigma Mobed ; lobes long, linear. Capsule globose, mucronate. Seeds angular, 

 brown* 



gab. Cultivated grounds; near Downingtown: rare. Fl. June— July. TV. Aug. 



Obs. This is an introduced plant; and, happily, rare in the county. Collected 

 by D. ToWHSBOT, Esq. in 1831. It has been found exceedingly pernicious in colli 

 1 grounds, in Europe,— choking and destroying whole crops; and is, moreover, 

 rt-ry difficult to subdue. Nothing short of total eradication will effect its destruc- 

 tion* It therefore behoves our farmers to attend to it, wheneverthey find it on their 

 iremiscs. Prof Eaton and Dr. Berk arc entirely mistaken in supposing this ma> 

 he the C.sagittifolius, of Mx. I have received the latter from my friend Mr. CUB 

 tlfl, of N. Carolina; and find it to be a totally distinct plant.
