It often falls to pinnately parted, with 3-7 pairs of lobes, long and shaped lobes at the apex, pointed or hooked at the apex, long and narrow at the base, and few hairs. The involucral bract has three layers, the tips of the outer two surfaces have few small angles, and the inner 1 layer is twice as long as the outer layer.

3. Dandelion leaves. It is long and inverted in the northeast of China, 9-20cm long and 2-5cm wide. The big head is pinnately cleft or deeply cleft, the lobes are slightly backward, triangular or narrowly triangular, the top lobe is large, oblate rhombic or triangular, and the four sides are pubescent. The outer involucral bracts are hornless or angular, and the inner layer is 2-2.5 times longer than the hornless outer layer.
