The spateligen to lanceolate basal leaves have a denticulate to coarsely toothed leaf margin sinuate. The upper leaf surface and the leaf edge can be hairy to glabrous significantly. From the best three to six rarely up to ten stems leaves the lower spatulate as the basal leaves or broad - lanceolate, ovate to obovate are narrowed with broad and sharp teeth and a handle, the upper often short and ovate, all with geöhrtem or heart-shaped, wide Spreitengrund amplexicaul and usually smaller and smaller towards the top.

The flowering period extends from June to August. The highly bifurcated to loose Rispige total inflorescence usually has two to four (one to six) branches and he seldom contains only two, usually 5 to 25 basket- shaped part inflorescences. The mostly bare hairy bracts are 10 to 16 millimeters long and abundant glandular. The flower heads contain only ray florets. The pale to deep yellow ray florets have strongly ciliated Kronzähne.
