Plants mostly 450-900 mm high, sheathed below by prominent, pale, dry-membranous, often irregularly torn cataphylls. Corm 12-18 mm diam.; tunics of medium-textured fibres. Stem usually with 2 to 5 short branches up to 5 mm long, branches subtended by pale, dry, attenuate scale-like bracts and prophylls 2-4 mm long. Leaves 3, lower 2 linear ± 1/2 as long as stem, mostly 1.5-2.0 mm wide (when alive), leathery succulent, main vein slightly raised; margins thickened and fleshy; uppermost leaf entirely sheathing. Main spike 2-or 3-flowered, lateral spikes 1-or 2(3)-flowered; bracts silvery membranous, translucent with darker veins, 9-11 mm long, outer 3-veined and 3-lobed to 3 toothed, inner 2-veined, shallowly forked at apex. Flowers nodding, white with a pale bluish cast, with pale green marks at tepal bases, faintly rose-scented; perianth tube broadly funnel-shaped, ± 5 mm long; tepals spreading distally, ovate, 15-16 x 6.5-7.5 mm, outer tepals wider than inner. Filaments ± 5 mm long, exserted ± 2 mm from tube; anthers 4.5-5.0 mm long, parallel or slightly diverging when flower fully open. Style dividing opposite lower 1/3 of anthers, branches ± 2 mm long.
