The leaves are obovate-lanceolate, obovate-lanceolate or oblong-lanceolate, the apex is blunt or acute, the edge is sometimes wavy or pinnately parted, sometimes pinnately parted or pinnately parted, the top lobe is large, triangular or triangular-halberd-shaped, whole or dentate, with 3-5 lobes on each side. This is an academic description. Simply put, the leaves are serrated, triangular, small egg-shaped, and the bottom of the stem is purple. The roots have obvious taproots, which are long and brown. After the roots of dandelion were cut off, they were milky white and smelled a little bitter. In the process of picking, there will be a plant whose leaves are similar to dandelion, which will confuse us and attract our attention. Its roots are whisker-shaped, and there is no obvious main root. The bottom of the leaf-cutting stem is not purple, and there are obvious hairs on the leaves. Don't pick such fake dandelions.
