How to identify sea sand

1. Morphological identification

The sea sand is a perennial herb, which is about 1 to 5 meters tall. The plant is relatively tall, and the rhizome underneath grows horizontally. It has a relatively tough texture and many small fibrous roots distributed on the edges. The surface color is dark brown, which looks relatively dark, and is covered with some small hairs.

2. Leaf identification

There are a lot of them growing on the leaves, distributed on both sides of the short branches on the stem. They look symmetrical, and there are sparsely distributed short hairs on the leaf axis. In summer, tassel-like spikelets grow on the underside of the leaves. The spikes are about 2 to 5 mm long and have small warts on the surface.
