their flowers, which continued expanded during the noon-day 
heat, and then quickly closed. This singular plant is evidently 
augmenting its range in this vicinity. Within a few years 
past, it was located in two or three places ; now it is plenti- 
fully fov.nd in numerous dirty shallow ponds, on clayey soil, 
on the Pennsylvania side of the Delaware, and I last summer 
detected it in profusion in Jersey. I am inclined to think it is 
not so circumscribed in its geographical range, as Mr. Nuttall 
says it is, for I have flnind it in small quantities in the state of 
Delaware, on the road from New Castle to Frenchtown, and 
also in Maryland, on the Baltimore road, about two miles from 
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 ferry to 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, found every where in the greatest 
profusion, in the shallow water of the Schuylkill, but particu- 
larly abundant opposite to Belmont. It flowers at low-tide, or 
rather its flowers are expanded 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 stream. I have 
collected many specimens of this plant, in company with Dr. 
Eberle, on the banks of the Conestogoe creek, near Lancaster, 
rooting and flowering in the earth* Perennial* Always in 
full flower about the 20th of July.
