Sophora japonica, a famous Latin country? Natans (L.) owns it.

Stems slender, transverse, rootless, densely covered with brown short hairs. ? Three leaves (8 leaves) of Sophora japonica are in rotation, two of which float on the water, one of which is as fine as silk, forming false roots in the water, with dense knotted coarse hairs. The water surface leaves are closely arranged on both sides of the stem, which are shaped like Sophora japonica leaves. The leaves are oblong or oval, 8-13cm long and 5-8mm wide. The apex is blunt, the base is round or slightly monarch-shaped, and the midvein is obvious. There are 4 ~ 8 sporangia at the base of underwater leaves. There are differences in size, megaspore fruit is small, and there are a few large sporangia with short stalks, each containing 1 3 microspores. The fruit is slightly larger, with many small sporangia with long stalks, and each sporangia has 64 microspores.
