their flowers, which continued expanded during- the noon-du\ 

 heat, Hid then quickly closed. This singular plant is evidently 

 augmenting its range in this vicinity. Within a few jears 

 past, it was located m two or three places ; now it I ti- 



fully found in numerous dirty shallow ponds, on (! >il, 



on the Pennsylvania side of the Delaware, and I last tummer 

 detected it in profusion in Jersey. I am inclined to think it is 

 not so circumscribed in its geographical range, as Mr. Nuitall 

 says it is, for 1 have found it in small quantities in the state of 

 Delaware, on the road from New Castle to I renchtown. and 

 also in Maryland, on the Baltimore road, about two miles AS m 

 Wise's tavern, (23 miles from Baltimore). In the neighbour- 

 hood of Philadelphia, common ; in the stagnant shallow waters, 

 on yellow clayey soil, opposite to the entrance to the Wood- 

 lands, and close to the road, abundant ; in ditches in the Neck, 

 and on the road to Lemon hill, frequent In a ditch on the 

 south side of the road from Market-street firry t> Cooper's 

 creek, Jersey, and about three quarters of a mile from the 

 ferry, in great profusion. Perennial. July, August.

An aquatic submersed plant, looking like long grass, and 

 generally mistaken for it, round every where in the greatest 

 profusion, in the shallow water of the Schuylkill, but particu- 

 larly abundatit opposite to Belmont. It flowers at low-tide, or 

 rather its flowers are expended and visible at that time. They 

 are of a beautiful yellow colour, and have a pleasing appear- 

 ance when fully opened on the surface of the stn an . I ha\e 

 collected man} specimens of this plant, in company with Dr. 

 Bberk . on the banks of the Concstogoc net k, near Lancaster,
