Ottelia japonicum
is an annual herb that occurs in paddies, water ditches, ponds, or
similar environments. It lays its leaves in water. The blades are
10-30cm long, 2-15cm wide, and broadly lanceolate, with long
petioles and margins that curl in a wave-like pattern. Flower stalks
arise among the leaves, and 2-3 cm in diameter, white or light
red-tinged flowers are on the water's surface. Flowers are bisexual;
stamens are 3-6 in number, styles are 6, and both are yellow. Bloom
time: August to October. |
