Plants slender, 180-350 mm high. Corms globose, 7-10 mm diam.; tunics of fine fibres. Stem simple or rarely 1-branched. Leaves mostly (2)3, occasionally 4 but then uppermost very small, ± linear to narrowly sword-shaped, 1/4-1/2 as long as stem, mostly 1.5-3.0 mm wide, relatively soft-textured, pale grey-green, when alive main vein slightly raised (appearing thickened when dry), margins not raised (rarely undulate, then blade up to 5 mm wide). Spike mostly 4-to 10-flowered, flowers mostly 10-15 mm apart; bracts 2-3 mm long. Flowers nodding, deep magenta with tepal bases yellow edged with darker magenta (or pale pink or white, throat pale yellow); perianth tube 3.0-3.5 mm long, expanded in upper 1 mm; tepals 8-9 x 4-5 mm, oriented vertically with lowermost tepals recurved. Filaments unilateral, ± 2 mm long; anthers 2.0-2.5 mm long, parallel. Style with branches ± 1 mm long, reaching to ± middle of filaments.
