Family, Water Lily. Color, yellow. Leaves growing well out of water, large, 18 to 20 inches across, roundish, sinking in the center, where the stalk joins the blade. Sepals and petals, like those of the water lily. Summer.
The flower is from 1 to 5 inches in diameter, scentless, growing, as do the leaves, on tall stems, from a rootstock. The numerous pistils are hidden in a concave receptacle, and they produce bean-like, eatable seeds. The plant also produces edible tubers. Found in a few ponds in southern Connecticut, westward and southward; rare in the Middle States. Dr. Gray says, probably introduced by Indians.
