Diagnosis

Stems 40–50 cm tall. Rosulate leaves narrowly lanceolate to lanceolate, base narrowly cuneate, apex triangular, with small serrate teeth, rather thick, grass-green, with sparse simple hairs 0.5–1 mm long and sparse to rather dense stellate hairs above, on short petioles. Cauline leaves similar, ca. 3. Phyllaries broadly triangular, with rather acute apex, 10–11 mm long, grey-green, with or without a few simple hairs at the base, with rather dense to dense glandular hairs 0.5–0.8 (1) mm long and sparse to rather dense stellate hairs throughout, apex with few short ciliae. Synflorescence branches without simple hairs, with sparse glandular hairs 0.3–0.5 mm long and stellate hairs. Styles with slightly dark (yellowish) papillae. Ligules glabrous.
