Plants stemless or short-caulescent, sometimes branching. Leaves subrosulate, 10-15 cm long, recurving and often more or less secund, covered with subspreading cinereous scales; sheaths variable in size, distinct; blades narrowly triangular, attenuate, involutesubulate for most of their length, 8 mm wide. Scape erect or slightly curved, slender, largely obscured by the leaves; scape-bracts erect, densely imbricate, elliptic with foliaceous laminae, membranaceous, subinflated, roseate, lepidote. Inflorescence simple and polystichous-flowered by the reduction of the spikes to a single flower each, densely fusiform or ellipsoid, 2-8-flowered, 5-6 cm long; axis straight, slender, short, lepidote; primary bracts like the upper scape-bracts but obtuse or apiculate, ample, 35-40 mm long, much exceeding the sepals. Floral bracts lanceolate, membranaceous, much shorter than the sepals; flowers erect. Sepals lanceolate, acute, membranaceous, 10-30 mm long, the posterior narrowly carinate; petals linear, tubular-erect; 4-5 cm long, violet; stamens and pistil exserted. Capsule subcylindric, equaling the sepals.
