Stem erect or flexed slightly outward above sheath of second leaf, rarely with short branch from upper leaf axil. Leaves (3)4(5), lowermost reaching base of spike or not, linear or falcate, 60-130(-190) x 1-3(-4) mm, thick-textured and plane with main vein not thickened or raised when fresh and usually without evident secondary veins, rarely with 1 secondary vein visible on each side, uppermost leaf entirely sheathing, well separated from spike. Spike erect, moderately densely 5-to 25-flowered; bracts shortly overlapping, outer 3-5 mm long, up to 1 internode long, acute, green below or entirely brown and leathery with narrow membranous margins and papery tip, without evident veining, inner ± as long as or slightly longer, ± membranous with narrow brown zone along veins. Flowers suberect, pale blue, lower 3 tepals white at base with purple median chevron in lower 1/4, strongly honey-scented, perianth subactinomorphic; tube narrowly funnel-shaped, 1.0-1.5 mm long, included in bract; tepals elliptical-oblanceolate, subequal, spreading and slightly cupped, 7-9 x 3-4 mm. Stamens unilateral but laterals slightly spreading; filaments arcuate, 3-4 mm long, exserted 1.5-2.5 mm from tube; anthers 4-5 mm long, dark blue; pollen pale blue.
