Trapa japonica
is an annual that grows in colonies in ponds
or marshes. Leaves floating on the water surface are 3-6 cm in
length and width, with an overall diamond shape, glossy surfaces,
hairs on the back sides, and petioles. The middle parts of the
petioles swell in a spindle shape and play the role of bladders.
Flowers, white, measure about 1cm in diameter and occasionally tinge
light red, with four petals, sepals, and stamens. Bloom time:
June-October. |
