Stem slender to moderately stout, suberect, simple or rarely with 1 or 2 short suberect branches, 2-3 mm diam. Basal leaves 1 to 3, dry at flowering, blades lanceolate to linear-lanceolate, 150-320 x 5-20 mm, acuminate, (2)3-to 5-veined, narrowed below (not pseudopetiolate); cauline leaves 4 or 5, lowermost small, leaf-like or subulate and clasping, upper 1 or 2 bract-like, dry and reddish brown. Spike moderately densely or laxly 3-to 10-flowered, 20-160 mm long, lateral spikes 1-to 3-flowered; bracts dry, brown, leathery, lanceolate, (12-)15-50 mm long, acute to acuminate, inner up to 9 mm longer than outer. Flowers zygomorphic, pale to deep salmon-pink or mauve-pink, lower tepals with red median streak or line, unscented; perianth tube subcylindric or widening slightly and evenly from near base, straight or slightly curved, (20-)40-70 mm long; tepals unequal, dorsal arched over stamens and recurved distally, oblanceolate, 25-40 x 6-10 mm, obtuse or subacute, others suberect but recurved in distal half, oblanceolate-spathulate, 18-35 x 4-8 mm, lower 3 joined for 4-8 mm. Filaments arched, later suberect, 15-20 mm long; anthers 8-10 mm long, purple, with recurved bipartite apiculus 1.5-2.0 mm long. Style (30-)60-90 mm long, dividing shortly below or beyond anther tips, branches 5-7 mm long. Capsules inflated, ellipsoid or ovoid, 20-30 x 10-12 mm. Seeds up to 8 mm long, usually broadly winged on angles at base and apex and narrowly so laterally.
