Leaves 2 to 8, all evidently basal, terete-filiform and narrowly 4-grooved, 0.5-1.5 mm diam. Peduncles up to 5, semi-terete, recurved but straightening and suberect in fruit; outer bracts greenish or purplish, with narrow, colourless membranous margins, 20-30 mm long, closely veined (± 8 veins/mm), inner bracts with wide, brown or brown-streaked membranous margins. Flowers old-rose-pink to terracotta-coloured with pale or greenish yellow cup, with purple-reddish blotches in throat with median line extending into cup, outer tepals irregularly streaked on reverse; perianth tube funnel-shaped, 5-8 mm long; tepals oblanceolate, (25-)30-40(-50) x 7-14 mm. Filaments (6-)9-12 mm long, pilose basally; anthers 7-12 mm long, yellow or with dark lines. Style usually dividing opposite upper half of anthers. Capsules oblong or ellipsoid, acute and shortly beaked, ± 10 mm long.
