Plant with a tubular or utriculate, 15-50 cm tall rosette. Leaves 11-47 cm long, the outer ones often much reduced and sheath-like; sheaths suborbicular to oblong, densely imbricate, 6-24 cm long, very densely brown-appressed-lepidote; blades erect, ligulate or narrowly subtriangular, often undulate near the base, rounded or obtuse, but sometimes attenuate. Inflorescence with the branches often turning to one side (secund); scape sparsely lepidote or floccose; axis often curved; rachis persistently lepidote. Sepals 4.5-5 mm long, subdensely lepidote throughout.
