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
corollas, 3,4cm in diameter, are deep into five segments; their tips
have one dent each, and the margins are cleft in a thread way.
Stamens are 5 in number and pistils 1. Bloom time: June-August. |
