Diagnosis

Stems 30–70 cm tall. Basal leaves reduced in size, often withering at anthesis; cauline leaves 5–10, decreasing in size from the stem base, lowermost ones narrowly oblong-lanceolate, base narrowly cuneate to attenuated, apex narrowly triangular, with sparse minute teeth, rigid, greyish-green, glabrous, but with sparse to rather dense stellate hairs above, on indistinct petioles. Phyllaries (narrowly) triangular, with acute apex, 9–10 mm long, dark grey-green, without or with solitary to very rare black-based to half-black simple hairs 0.5–1 mm long, sparse glandular hairs 0.2–0.5 mm long mostly along the middle line and sparse to rather dense stellate hairs throughout, apex without ciliae. Synflorescence branches usually without simple and glandular hairs and with stellate pubescence. Styles with black papillae. Ligules glabrous.
