A very beautiful plant, two, or two and a half feet hig-h, 

 With a single lieart-shapeil leaf, and tine Prussian-blue Mowers 



in a crowded spike On the marshy shores ofthc Delaware, 



Schuylkill, and .smaller streams emptying 1 into them, growing 

 with splatterdocks, very common and rery abundant Peren-

There is a smaller variety with long, narrow hastate or tri- 

 angular leaves, growing 1 along the holders of the Delaware 

 w the nary-yard, that appears to tit Pursh's description 

 of P. a lia, which he collected in the mountain-lakes; 



and I really think it is the plant intended by that author, under 

 the name just mentioned. I hare collected many specimens, 

 but in none is the difference in the breadth of the corolla seg- 

 ments observable. I therefore consider it u mere variety. 

 The plant I allude to, is distinct from Muhlenberg's P. lan- 

 cit'olia, of which I have examined specimens in the Muhl. 

 II i Mr. Klliot seems inclined to the opinion that even that 

 is but a variety of P. cordata. I should not think so from Muhl- 

 enberg's specimens.
