What cultivar does this plant most closely resemble and how does it differ? This plant resembles no other plant to my knowledge.

Unusual characteristics or comments: N. ‘Yellow Watermelon’ blooms very well and the substantial flowers are held high above the water on strong pedicles. The root travels about a foot a year in fertile soil in a mud pond. Has a large spread of leaves. The flowers are continuous and uniquely beautiful but the real show is the leaves.
