Plants 60-150 mm high, 4-to 10-branched, branches subtended by bracts (1-)2-5 mm long, these sometimes leaf-like below and longer, stem ± flexuose, compressed and 2-winged. Corm obconic, 10-15 mm diam., tunics blackish, splitting vertically from base and apex. Leaves 2 or 3, lower 1(2) basal, usually falcate (or ± lanceolate), 100-130 x 4-8(-10) mm, subacute to acute, with prominent main vein and 1 or a pair of secondary veins on either side slightly less prominent, margins ± straight, slightly undulate, rarely slightly crisped, uppermost leaf inserted in middle 1/3 of stem, 25-80 mm long, narrowly oblong, not or hardly sheathing at base. Inflorescence a congested, flat-topped false panicle, ultimate branchlets bearing 1 or 2 sessile flowers; bracts green, leathery, 3.5-7.0 mm long, margins usually red, obtuse or inner slightly emarginate. Flowers actinomorphic, light to dark blue with white throat and lower half of tepals with white, bracket-shaped band (rarely ± white with pale blue markings), not scented; perianth tube funnel-shaped, 4-7(-8) mm long; tepals elliptic, obtuse, 6-10 x 2.3-3.5 mm. Stamens symmetrically arranged around style; filaments 5-6 mm long, exserted 3-4 mm; anthers 1.8-3.0 mm long, usually blue; pollen blue to grey, or ± white. Style dividing between base and upper 1/3 of anthers, often deflexed in older flowers; style branches 1.5-2.0 mm long, divided for ± 1/2 their length. Capsules top-shaped, 3-lobed, 4.5-6.5 mm long, with up to 6 seeds per locule. Seeds ovoid, reticulately sculptured, flattened to concave at chalazal end, dark brown, 0.7-1.0 mm long; funicular collar up to 0.5 mm long.
