It is a grass flower. Such trees are usually found in paddy fields. These are again known as weeds. This weed or grass flower grows in large quantities in our paddy field. It is not necessary to remove them knowingly, otherwise they cause a lot of damage to the rice crop. Also, where these rice seeds are transplanted to produce rice seedlings, such weeds grow in abundance and cause damage to the crop. They are much taller than rice plants.
The leaves of this grass and the leaves of rice plants are similar green in color. In the first stage they are not well understood even if they are grown with the Dan tree. But after some time these plants become very tall and bigger than rice plants. And the flowers that appear on them after a few days produce small dots of seeds, and when they turn black, they fall by themselves to the ground. As a result, this grass or weeds grow separately from them. This weed has grown in large numbers in our paddy field this year. When I went to collect paddy in the morning and saw them, most of these grasses were visible. Then I took some photos.
