Plants 200-400 mm high. Corm globose, 7-15 mm diam.; tunics of fine to medium-textured netted fibres, sometimes thickened and claw-like below. Stem flexed at base of spike, simple or rarely with a single branch subtended by silvery, attenuate bracts and prophylls up to 4 mm long. Leaves 3, lower 2 linear-filiform, 0.8-1.2 mm wide, main vein heavily thickened and raised, thickened secondary veins sometimes present, margins not thickened, uppermost leaf usually entirely sheathing. Spike slightly flexuose, 1-or 2(3)-flowered; bracts 6-8 mm long, outer 3-veined and 3-toothed, inner ± as long as outer, 2-veined, forked apically. Flowers nodding, salver-shaped, with unilateral stamens, white or flushed pale mauve, with a ring of dark streaks at tube mouth, pale mauve outside, with dark lines on tube; perianth tube cylindric, (12-)15-20 mm long, ± 2 mm diam., straight; tepals ± elliptic, subequal, 12-15 x 6-8 mm, spreading at right angles to tube.
