been established in ponds and lakes in Kent, and there 

 flowered freely for several years in succession. 



The figure of the rootstock here given is taken from 

 Herbarium specimens collected in the St. John's River by 

 Mr. Curtiss. It has also been found in the Miami by Mr. 

 Grarber, and in a few other localities, all in Florida. 



Desce. Rootstock cylindric or oblong, apparently not 

 creeping. Peduncles and petioles dark green. Leaves two 

 to six inches in diameter, orbicular elliptic or broadly 

 oblong, green often blotched with dark red, margin entire 

 or waved ; basal lobes subacute or obtuse, parallel, with a 

 narrow sinus. Floivers four inches in diameter, pale 

 yellow, opening at noon and remaining expanded till sunset. 

 Sepals linear-oblong or oblong-lanceolate, subacute, rather 

 darker yellow than the petals, with a faint rosy tinge 

 externally towards the margin ; nerves very slender. Petals 

 of the same form as the sepals, but rather paler, the inner 

 shorter and broader. Stamens numerous, suberect ; filaments 

 of the outer dilated in the middle, and much longer than 

 the anther ; of the outermost short, broad, concave, and 

 petaloid ; of the innermost narrower and linear ; anthers 

 linear, connective hardly produced, tip rounded; cells 

 parallel. Stigmatic rays about eight, short, broad, obtuse, 

 incurved, inappendiculate. — J. D. H.
