on each side of the stigmas.

Oba, First recognized in the Brandywine, En 1828, by Mr. JosiruA Hoopes. 

 Every boy, and fisherman, who goes barefoot into the shallows of the Brandy* inc. 

 is familiar with this plant, without suspecting that it ovor bears visible flowers, li 

 had always passed for some kind of crisp aquatic mops, until Mr. Hoopbs detected 



it in bloom. It flowers much more abundantly when the waters are eo shallow as 

 occasionally to expose the plant to the air. 



Our species comes very near the P. abrotanoides^ described by Mr. Nut fa?/, in 

 the Journal of the Philadelphia Academy, Vol. 7. p. 105,— except that the pedun- 

 cles are solitary* Mic/iaux's figure seems to have been taken from a dried speci- 

 men ; and does not well represent the habit of the plant. No other species, than 

 the two here mentioned, are known in the United States.

Qbs. I strongly suspect this is an introduced plant,— at least in this Countv : 

 and it seems to be very closely allied to the V. olitoria, of Europe. D. ToWtfaM&p 

 Ksqr. found it with white flowers, near Black Rock. The young leaves ara saiii 

 te make a good salad ; but 1 believe they are not used here.
