Plants (80-)120-300 mm high. Corm globose, 8-10 mm diam., slightly asymmetric with one side obliquely flattened below and extended downward shortly, tunics dark brown, imbricate, notched below into ± regular segments, drawn into points above. Stem suberect or inclined, flexed at base of spike, minutely and sparsely puberulous below, sometimes with 1 branch. Leaves usually 3, sometimes 4, lower 2 basal, ± as long as stem, 2-4 mm wide, third leaf cauline, sheathing below, shorter than basal, fourth leaf, if present, shortest and becoming scale-like, blades evidently flat but margins raised and narrowly winged, main vein also raised, with margins, main and sometimes secondary vein edges ciliate. Spike inclined, flexuose, 2-to 8-flowered; bracts green, becoming dry, membranous and pale near apex, outer mostly 8-12 mm long, inner smaller, enclosed by outer. Flowers actinomorphic, salver-shaped, blue to blue-mauve; perianth tube cylindric, widening near throat, (7)8-11 mm long, reaching apex or just exceeding bracts; tepals elliptic, 14-18 x ± 4 mm. Filaments erect, equal, 5-6 mm long; anthers usually 4-6 mm long, yellow; pollen yellow. Style dividing opposite middle to upper 1/3 of anthers, often tilted downward, branches 2-3 mm long.
