Hab. Thin soils: old fields, and pastures: common. 1 to 2 feet high: flowers white, odorous. 



Obs. The infusion of this is a popular medicine in dysenteries; but probably not very valuable. I strong:- 

 ly suspect that this is the plant referred to by Barton, in Flor. Philad. under G- margaritaceum, as bem^ 

 " every where abundant" in old fields, &c- It is, however, certainly distinct from G- margaritaceum, as I 

 have received it, from New England.

Obs. This foreigner is gradually becoming naturalized. The infusion is highly popular among the good 

 ladies, as an emmenagoguc; and it certainly possesses some tonic virtues,— combined with pretty strong arc- 

 malic properties.

Hab. Fields, meadows, and borders of woods: frequent. 12 to 20 inches high: rays white, disk yellow. 



Obt. This foreigner is perhaps the vilest weed which has yet invaded our farms; and is spreading itself 

 in a manner calculated to excite the serious concern of reflecting Agriculturists. It is a plant which cattle 

 generally refuse to eat: it takes almost exclusive possession of the soil,— is difficult to eradicate, complete- 

 ly'— and produces seeds in great abundance. It has not, as yet, become so prevalent in this immediate 

 vicinity, as it is in several other districts,— especially to the northward and eastward of us; but there can be 

 little doubt tliat it will speedily pervade every part of our country, — unless resisted by the vigilant and ac- 

 tive co-operation of the whole agricultural community. It i? in vain for one, or a ie'w, to contend agains; 

 suchapest, whilst Others supiaely or nesligently permit itto flgurish on their premises.
