Nymphoides peltata is an aquatic perennial herb
inhabiting ponds and marshes, the rhizomes crawling long in the
bottom's mud and bearing thick, long stems. Leaves, with long
petioles, float on the water surface, are 5-10cm in diameter, ovate-
or orbicular-shaped, the bases deep-heart-shaped, and the margins
have shallow, wavy serrations around. The leaf's bottom side tinges
are brown-purple. Axils emerge flower stalks and put yellow flowers
on the water's surface. The 3,4cm in diameter corollas are deep into
five segments; their tips have one dent each, and the margins are
cleft in a thread-like manner. Stamens are 5 in number and pistils
