Stem ± straight, simple or 1–3-branched from lower nodes, lateral rhipidia sessile, each subtended by sheathing leaf often entirely concealing rhipidia. Foliage leaves 3 or 4(5), linear, ascending below, bent and trailing distally, lowermost longest, 250–600 mm long, progressively shorter above, 6–12(–20) mm wide, ± flat or channeled. Rhipidial spathes attenuate, dry at tips, inner 35–5.5(–7.5) mm long, outer slightly shorter. Flowers fugaceous, stellate, pale yellow, usually only outer tepal limbs with inconspicuous, slightly darker yellow nectar guides, odourless or faintly scented; tepals with claws ± 2 mm long clasping filament column, limbs spreading, outer with limbs 19–27 × 8–11 mm, inner 16–23 × 6–9 mm. Filaments 4–6 mm long, united in lower 2–3 mm; anthers 5–6 mm long before anthesis, yellow; pollen yellow. Ovary 8–12 mm long, exserted, style branches divided to base in filiform, horizontally extended arms 4–6 mm long. Capsules obovoid-clavate, truncate, 12–16(–23) mm long, exserted, splitting for 1/2 to 3/4 their length. Seeds angular, 2.0–2.3 mm long. Chromosome number 2n = 24.
