—Description: “Habit of a very broad-leaved Hieracium Čelakovskyanum , but with 6 stem leaves, the middle ones undistinctly amplexicaule at base; also very similar to H. longifolium . Stems 30 cm, violet at base, thin, the lower part moderately to subdensely hairy by simple hairs, the upper part sparsely hairy by simple hairs, only with one capitulum, peduncle moderately hairy by thickfooted glandular hairs and simple hairs. Involucre 10 mm, very thick, phyllaries in many rows, dark, not very wide, obtuse to subacute, the inner with green margin, all with moderate simple and glandular hairs and sparse stellate hairs. Ligulae light yellow, ciliate. Stem leaves (ca. 6) together with petiole up to 10–15 x 10–35 mm, ovate-lanceolate to elliptic-lanceolate, short to long narrowed, longly and widely petiolate, apex subacute to acute, margins short dentate to denticulate, leaves light to yellowish green, petiole and margin with many +/- short rigid and simple hairs, the upper surface with few to moderate rigid simple hairs, glandular hairs only few along the margin. Outer basal leaves small, ovate-lanceolate, rapidly narrowed into a winged petiole, with rigid simple hairs, the lowest and the second stem leaf with the shape of the basal leaves, but the second leaf already much smaller, lanceolate, with a shorter petiole, the other leaves petiole-like narrowed (sometimes undistinctly panduriform), sessile or indistinctly semiamplexicaul, the upper leaves small to bract-like, margin denticulate, with moderate rigid, short simple hairs.”— K. H. Zahn (emend.).
