Although the specimens are incomplete, and without ripe fruit, I 

 think they cannot belong to the European Nasturtium sylvestre; but 

 they accord very well with what I take for a variety of N. palustre in 

 the Northern United States with more or less hairy stems, and with 

 rather shorter pods than I have ever observed in the European plant.

Our specimens are indifferent, wanting the lower leaves. The 

 pods are not as large as they are described by Dr. Hooker, being only 

 an inch long, and barely a line wide. The radicle is occasionally 

 oblique, as in certain Sisymbria.
