 ner over the nerve as to make the stalks appear almost round or at least semi- 

 cylindrical. Between these leaves, at their base, on the under (!) side, may be 

 discovered other lesser leaves, or auricles, nearly of the same shape with the lar- 

 ger ones. In the young plants the leaves are round, plain, alternately and more 

 thinly set, very variable in size, and without auricles. The fructifications we 

 have never yet been able to discover. In bogs, rivulets, and cascades, by the sides

 a microscope, but none on the under side."
