Stems 50–75 cm tall, with simple hairs 1.5–2 mm long at the base.

Phyllaries triangular, with narrowly acute apex, ca. 11 mm long, dark grey-green, with rare to sparse black-based simple hairs 0.5–0.8 mm long, dense glandular hairs 0.1–0.3 mm long on the whole surface and rather dense stellate hairs in the basal part, apex without ciliae. Synflorescence branches with or without very rare simple hairs and glandular hairs 0.1–0.2 mm long, with stellate pubescence. Styles with yellow papillae. Ligules glabrous.
