Characteristics

Plants (20-)40-200 mm high. Corm globose, obliquely flattened toward base with crescent-shaped basal ridge ± as wide as corm, 7-15 mm diam., tunics splitting into fine parallel fibrils along ridge, sometimes forming fibrous neck above. Stem subterranean or aerial, exserted up to 200 mm. Leaves 3 to 5 (rarely more), lowermost 2 basal, terete or compressed-cylindric and narrowly 4-grooved, 0.5-1.5 mm diam., sometimes ciliolate along rib margins. Peduncles mostly up to 4, rarely up to 12, semiterete, sometimes ciliolate on sharp angles, suberect or spreading in fruit; outer bracts green with narrow membranous margins, 10-25 mm long, widely striate (3 or 4 veins/mm), inner bracts with broad, colourless membranous margins. Flowers pale violet, lilac-pink, white or cream-coloured, sometimes with dark lines in throat, cup pale to golden-yellow or orange, outer tepals green or irregularly blotched or streaked on reverse, sweetly scented; perianth tube funnel-shaped, 3-7 mm long; tepals elliptic, 12-40 x 4-12 mm. Filaments 4-10 mm long, pilose at base, yellow; anthers 4-9 mm long, pale or golden-yellow. Style dividing below or above anther tips, branches 2-4 mm long, divided halfway. Capsules ellipsoid, 8-10 mm long.
