Plants 100‑200(‑300) mm high, stem simple or 1- or 2-branched from base. Corm globose, ± 15 mm diam., tunics of fine pale closely matted fibres. Leaves 7–9, ± basal, ± two thirds as long as spike, lanceolate(–oblong), 9–12 mm wide, abruptly expanded adaxially above sheath, obliquely apiculate, closely veined with ± prominent central vein. Spike 1–2(–3)-flowered, weakly flexuose, flowers spirally arranged; bracts dry, crinkled, translucent with light brown streaks, lateral margins lightly and irregularly serrate, 2–2.5 mm long, distally drawn into long tapering cusps, outer with 3 prominent veins, 3-cuspidate, inner with 2 prominent veins and 2-cuspidate. Flowers actinomorphic, bright yellow, tepals each with dark maroon-purple heart-shaped mark with central yellow streak in lower third, unscented; perianth tube funnel-shaped, 6–7 mm long, narrow basal part ± 2.5 mm long; tepals subequal, ± oblong, 27–35 × 8–10 mm. Stamens symmetrically arranged, filaments erect, 6–7 mm long, anthers linear, diverging, contiguous below, 9.5–11.0 mm long, pale yellow. Ovary globose, ± 2.5 mm long, style dividing opposite the lower third of anthers, branches filiform, 4.5–5 mm long, extending outward between upper third of anthers. Capsules ± globose, shortly stipitate on stalks ± 1 mm long, 6–9 × 5–6 mm, not splitting at apex, walls eventually fragmenting by horizontal cracks. Seeds reddish brown, up to 8 per locule, ± 2 mm diam. Chromosome number unknown. Flowering time: late August and September.
