The difference between rice bag grass and duck tuo grass

Difference 1: Leaf petiole

Everyone knows that there are petioles on the leaves, but the length or shape of the petioles is different for each plant, and the same is true for rice bag grass and duckweed. The petiole of the rice bag grass is very obvious and slightly longer; while the petiole of the duckweed is almost non-existent, and the leaves are directly connected to the stem.

Difference 2: The handle of the involucre

Most flowers are generally connected to the stem by the stalk of the involucre, but the involucre of the rice grass is directly connected to the stem without a stalk; the involucre of the duckweed is connected by a stalk, and the stalk is relatively long. So this is also an observation point.

Difference 3: Flower color

What often confuses people may be the color of the flowers, because they are all blue and the difference in shade is not much. However, the three petals of the rice bag grass are all blue, and the filaments in the stamens are also blue; the two petals of the duckweed are blue, but the petal near the bottom of the petal is white, and the filaments are also white.

Difference 3: Fruit

When the fruit is produced by the rice bag grass, there are three fruit chambers, two of which contain two fruits, which are what we often call seeds; when the fruit is produced by the duckweed grass, there are only two fruit chambers, each of which contains two seeds.

After reading the above differences, have you learned how to identify them? In fact, it is very simple. To sum it up, you need to look at the petiole, then the petiole of the involucre, then the flower, and finally the fruit of the flower, which is the seed. The easiest way is to look at the flowers as soon as you see it, because the fundamental difference between them lies in the flowers. As long as the filaments are white, it is duckweed, and if the filaments are blue, it is rice bag grass.

That’s all I’m going to introduce to you this time. In short, as long as you pay more attention to the flowers and plants around you, you will still see a lot of interesting things!
