Flowers are a beautiful thing, but do you know what the smallest flower in the world is? In ponds and rice fields, there is a plant called Wugen Ping. Its flower is the smallest flower in the world. The diameter of the flower is only the size of the tip of a sewing needle. In ordinary ponds and rice fields, there is a kind of aquatic plant floating on the surface of the water, which is the non-root-weed of the Lemna family. It has no roots or leaves. It is shaped like a small ball, about 1 mm long and less than 1 mm wide. For such a small plant, its flowers are even smaller. The diameter of the flower is only as large as the tip of a sewing needle. Note that I can’t see it yet, it can be regarded as the smallest flower in the world.
Rootweed is a kind of duckweed. It is too small, only more than 1 mm long and less than 1 mm wide, which is much smaller than sesame. The shape of Pingya is similar to that of common Pingya. They are flat on the top and bulge on the bottom. As the name suggests, this plant has no roots. Interestingly, this tiny plant also has flowers, which are of course smaller, only as big as needle tips.
The structure of P. arundinacea is very simple. The whole plant body has no difference between roots, stems and leaves. It has an oval appearance and is filled with small air chambers. It is mainly composed of parenchyma cells that can be used for photosynthesis. Because the plant body is too small, even the remaining vascular tissues of other duckweeds are completely degraded. How small is Wugenping? There are 11 species of Asparagus in the world. The smallest is Wolfia globosa. The plant is about 0.4-0.9mm long and small enough to pass through pinholes. Their fruits and seeds are even smaller than salt grains.
