The whole grass is wrinkled and curled mass. Root conical, more curved, 3-7cm long, surface brown, wrinkled, root head with brown work yellow-white velvet, some have fallen off. Leaves basal, much crumpled and broken, complete leaves anatropous

needle-shaped, 6-15cm long, 2-3.5cm wide, greenish brown or dark gray, apex pointed or obtuse, margins invertedly lobed or pinnatifid, lobes toothed or triangular, base attenuate, decurrently stalked, main veins on the lower surface

obvious, covered with arachnoid hairs. Flowering stems 1 to several, each with terminal guaniform hairs. Flowering stems 1 to several, each terminating in a capitulum; involucral bracts multilayered, outer involucral bracts several-layered, apex with or without a small horn, inner 1-layered 1.5-2 times longer than outer, apex with a small horn, corolla yellowish brown or yellowish white. Some of them are visible as long ellipsoid achenes with numerous white crown hairs. The odor is slightly bitter.

2, alkali dandelion Leaves obovate-technical shape or narrowly lanceolate, about 48cm long, 1.2-1.5cm wide, often more regularly inverted pinnatipartite, lobes 3-7 pairs, the apex of the apex of the lobes long on the shape of the apex pointed or hooked, the base of the base is narrow and long, a few glabrous. Involucral bracts 3-layered, outer 2 surfaces with apex several hornlets absent, inner 1 layer twice as long as outer.

3, Northeast dandelion leaves oblong-obtuse shape, 9-20cm long, 2-5cm wide, large head pinnatifid or status quo parted, lobes slightly inverted, triangular or narrowly triangular, apical lobes large, compressed rhombic or triangular, entire, both surfaces are sparsely pilose. Outer involucral bracts absent or with inconspicuous minute horns, inner layer 2-2.5 times longer than outer layer, without minute horns.

4, heterobracteate dandelion Petiole base slightly purplish red, covered with arachnid hairs; leaf oblanceolate, 12-15cm long, 3-4cm wide, apex pointed, base narrow, margin pinnately parted, lobes broadly or narrowly triangular, apex acute, entire or sparsely toothed on both surfaces covered with arachnid white hairs; old leaves nearly smooth. Involucral bracts 3-layered, outer layer with small horns, inner layer 1.5-2 times longer than outer layer, slightly horny.

5, Asian dandelion Leaves bar-shaped or narrowly lanceolate, 2.5-9cm long, 0.3-0.9cm wide, pinnately lobed to y lobed, lobes slightly inverted, triangular ship shape to bar, apical lobe is larger, or shaped or narrowly pilose, glabrous or sparsely pilose. Outer involucral bracts with inconspicuous minute horns, inner layer 2-2.5 times longer than outer layer, without conspicuous minute horns.

6, red stalked dandelion Petiole short, reddish purple-brown; leaf blade long obliquely shaped or broadly obliquely shaped, 8-12cm long, 2.5-3cm wide, light Rui obtuse, the base is narrowed, the edge with regular pinnately parted, lobes triangular, entire or sparsely toothed, the surface has a red blotch, both surfaces are arachnoid hairs. Involucral bracts 3-layered, inner layer 2.5 times longer than outer layer, purplish red, with small horns.

The one with many leaves, green in color, and long roots is preferable.
