A native of pools of sweet water, where it floats, often not reach- 

 ing the bottom with its roots. Flowering time the wet and cold 

 season. 



Root annual, fibrous — Leaves radical, petioled,- cordate, lobes 

 overlapping a little, margins somewhat scolloped, smooth, on the 

 upper side purplish green ; size various, the larger from four to six in- 

 ches long. — Petioles round, length various, on the upper side about 

 two inches below the leaf there is a viviparous tuberosity, which 

 produces the flowers as well as other leaves ana roots ; the old leaf 

 and the parent petiole decaying, leave this a new plant, each peti- 

 ole in succession doing the same. — Peduncles many, from the above- 

 mentioned tuberosity of the petiole, one-flowered, sufficiently long 

 to raise the flower above the water while expanded, afterwards they 

 drop into the water, and there ripen their seeds. — Flowers pure white, 

 about an inch in diameter. — Calyx five-leaved ; leaflets broad lance- 

 olate, permanent. — Corol of one petal ; divisions of the border oblong, 

 expanding with broad, membranaceous, waved, curled, ragged mar- 

 gins; down the middle of each of them runs a ridge, exactly similar 

 to one half of the divisions themselves, no hair on the flowers. Nec- 

 tary triple ; the exterior one consisting of while, ram o us filaments 

 crowning the mouth of the tube of the corol, as in Nerium ; the 

 middle one of five beautiful yellow, glandular bodies, which nearly fill 

 the mouth of the tube, standing alternate with the filaments ; and the 

 interior one of five hairy, yellow bodies, surrounding the base of the 

 germ. — Filaments inserted into the tube of the corol near its base. 

 Anthers oval — Style short. — Stigma two-cleft ; segments large, and 

 lobate.— Seeds a little compressed, scabrous. Receptacles parietal, 

 opposite, running down the sides of the capsules.
