Characteristics

Plants 140-240 mm high. Corm 10-15 mm diam.; tunics of coarse, matted fibres, accumulating with age. Stem erect. Leaves 4, lowermost exceeding spike, ± dry at flowering, linear, 200-250 x 2-3 mm, closely 3-or 4-ribbed, uppermost leaf with short blade 20-30 mm long. Spike erect, densely 7-to 15-flowered; bracts overlapping for 1/2-2/3 length, 8-10(-13) mm long and two or three internodes long, outer acute, either green below or entirely brown and leathery, conspicuously and closely veined, with narrow membranous margins, inner slightly shorter, ± membranous with narrow brown zones along veins. Flowers suberect, cream-coloured to pale flesh-pink, flushed purple on tube, lower three tepals with median linear maroon streak extending halfway along blade; perianth weakly zygomorphic; tube slightly curved outward in distal 3 mm, (17-)20-23 mm long, ± 1.5 mm diam. at mouth, ± cylindric but widening slightly distally, exserted 13-15 mm beyond bracts; tepals linear-oblanceolate, inner three slightly smaller, spreading and slightly cupped, 12-15 x 1.5-3.0 mm. Stamens arcuate; filaments 4-5 mm long, exserted 2-3 mm from tube; anthers 4 mm long, blackish purple; pollen purple. Style arching above anthers, dividing between base and middle of anthers, branches, ± 3 mm long, divided to near base. Capsules narrowly ovoid, 5-7 x 3 mm. Seeds ellipsoid-angled, ± 2 mm long, yellowish brown, testa striate-colliculate.
