Characteristics

Plants 120-250 mm high, with axillary cormlets below ground. Corm bell-shaped, ± 10 mm diam.; tunics dark brown, often glossy, basal margin finely serrated, teeth directed downward. Stem simple or more often branched and then mostly well above ground, ± terete. Leaves 3 to 6 (or more), lowermost usually exceeding others, linear, suberect or falcate, 2.0-3.5 mm wide, strongly ribbed, generally exceeding stem, up to 350 mm long, upper cauline leaves shorter, sometimes resembling bracts and not ribbed, usually subtending branches. Inflorescences 5-to 12-flowered spikes, usually crowded; outer bracts green or flushed reddish, often white to semitransparent below, firm, 8.5-12.0 mm long, obtuse or acute, usually folded in midline or channelled, margins hyaline, inner bracts 1/2-2/3 as long. Flowers zygomorphic, white or sometimes flushed with pink to lilac (aging pink), lower tepals often with pink to purple streak in midline and bearing tooth-like ridge in lower midline; perianth tube short, 7-10 mm long, narrow below, curved and widening toward apex; tepals unequal, lanceolate, acute, dorsal 14-16 mm long, erect, separating from tube below lower tepals, margins undulate, remaining tepals joined for ± 4 mm, upper lateral tepals sharply reflexed shortly above base, lower 3 tepals united for additional 2-3 mm, ± 12 mm long, bent at right angles shortly above base, directed downward distally. Stamens unilateral and arcuate; filaments ± 6 mm long, exserted 4 mm from tube; anthers ± 4 mm long, white; pollen white. Style dividing opposite anther tips; branches forked for ± 2/3 their length, recurved. Capsules obovoid, 4.5-7.0 mm long, apices of locules forming auriculate lobes decurrent on low locular ridges. Seeds ± globose, flattened at chalazal end, 1.0-1.2 mm diam., light brown.
