This is scarcely half the size of our common C. palustris. The re- 

 cumbent slems send forth roots from several of the lower joints, 

 creeping to a considerable extent. Leaves from 1 to 2 inches 

 broad, more triangular than heart-shaped, sharply crenate ; the 

 radical ones on very long s]er\der footstalks. Petals the colour 

 of the foregoing, about half as large, more obovate, or sometimes 

 obliquely wedge-shaped. Germens 7 or 8. A double variety of 

 this is cultivated about London.
