Rhizoma thick, creeping under ground as well as under water, covered over with

 Leaves erect on a petiole two feet long. Lamina 6-8" in diameter, concave in the 

 central part ; lobes very unequal, ovate, the segments reaching nearly to the middle 

 of the limb, with doubly dentate or shortly lobed margins. Scapes two feet high, 

 with a small cuneate, lobed or dentate leaf below the cyme. Cyme multiform, some-
