Dut occasionally met. with in Ct. and N. Y. Rhizoma creeping in mud in 

 depths of water from 2 or 3 to 6 f. From this arise the simple scapes and 

 petioles to the surface. Leaves 10—18' diam., the petioles inserted on one side 

 of the centre. Flowers several times larger than those of Nymphsea odorata, 

 and without fragrance. Petals concave, of a brilliant white, becoming yellow 

 towards the base. The nuts imbedded in the torus are about the size of acorns, 

 and are used for food by the Indians. June.
