Flowers pale-yellow to cream-coloured, the uppermost tepal sometimes flushed with red; perianth tube 18–25 mm long, nearly cylindric below, curving outward and expanded in the upper half; tepals unequal, the 3 upper tepals broadly elliptic-ovate, the uppermost (20)25–28 × c. 16 mm, larger than the others and hooded over the stamens, the upper lateral tepals about as long as to c. 5 mm shorter than the upper and c. 12 mm wide, directed forward and curving outward distally, the lower 3 tepals 12–16 × 7–10 mm and down-curved, the lowermost somewhat longer than the lower laterals.
Foliage leaves produced simultaneously with the flowers on the same shoot, 4–5, the lower 2–3 leaves basal or nearly so, about a third to half as long as the spike, 5–10 mm wide and narrowly lanceolate, the blades firm-textured with moderately raised and thickened midrib and margins; the upper 2–3 leaves cauline and largely or entirely sheathing, often imbricate.
Spike (2)3–7(10)-flowered; bracts pale-green, evidently becoming dry above, 24–30(40) mm long, the inner somewhat shorter than the outer.
Corms 15–20 mm in diameter; tunics light-brown, of brittle membranous layers, the outer becoming irregularly broken or fibrous.
Style dividing near the anther apices, style branches c 4.5 mm long.
Filaments c. 16 mm long, exserted 4–6 mm; anthers 8–12 mm long.
Capsules (18)20–24 mm long, ellipsoid-obovoid.
Plants 40–60 cm high.
Stem unbranched.
