Plants 55–85 cm high. Corms unknown. Foliage leaves 6, the lower 2 usually more or less basal and larger than the others, reaching to the base or middle of the spike, 4–5 mm wide, nearly linear, the midrib and margins slightly thickened; upper leaves cauline and progressively shorter above, the uppermost usually entirely sheathing. Stem simple or with a short branch. Spike 10–18-flowered, inclined from the base; bracts evidently membranous below and dry and brown above at anthesis, 12–16 mm long, the inner about two-thirds as long as the outer. Flowers pale-yellow or greenish, tepal markings if present unknown; perianth tube c. 10 mm long, obliquely infundibuliform, widening and curving outwards near the apex, c. 10 mm long; tepals unequal, the upper three 15–17 mm long, (often less when dry), larger than the others, broadly lanceolate, the uppermost inclined over the stamens, c. 12 mm wide, the lower 3 tepals united below for c. 2 mm, 9–10 mm long, abruptly expanded in the upper half, the apices inclined toward the ground. Filaments c. 10 mm long, exserted 6 mm; anthers c. 5.5 mm long. Style arching over the filaments, dividing between the base and middle of the anthers; style branches 2–3 mm long, never reaching the anther apices. Capsules c. 10 mm long, obovoid.
