Diagnosis

Stems 40–50 cm tall. Rosulate leaves narrowly lanceolate, base narrowly cuneate, apex narrowly triangular, with numerous minute teeth, rather thick and rigid, pale glaucous-green, glabrous above, with simple hairs ca. 2 mm long along the margins, on rather short petioles. Cauline leaves similar, 2–3. Phyllaries very narrowly triangular, with narrowly attenuated apex, ca. 11 mm long, grey-green, with sparse simple hairs 1–1.5 mm long, sparse to rather dense glandular hairs 0.1–0.3 (0.4) mm long and sparse to rather dense stellate hairs throughout, apex with numerous long flexuous ciliae. Synflorescence branches with sparse simple hairs, rare to sparse (rather dense) glandular hairs 0.1–0.2 (0.3) mm long and stellate hairs. Styles with discoloured papillae. Ligules glabrous.
