Leaves 3 to 9, lower 2 basal, straight or weakly to strongly sinuous, terete and narrowly 4-grooved or compressed and broadly 4-grooved, 0.5-4.0 mm diam., glabrous or ciliate on rib margins. Peduncles up to 9, hemiterete, glabrous or ciliolate along angles, suberect or spreading in fruit; outer bracts green with narrow, colourless or brown-flecked membranous margins, 10-25 mm long, finely striate (4 or 5 veins/mm), inner bracts with narrow or wider, colourless or brown-flecked membranous margins. Flowers magenta to salmon-pink, apricot-coloured or coppery orange, with or without reddish or violet blotches in the throat, with pale or golden-yellow cup, outer tepals mostly darker on reverse, sometimes with paler median stripe; perianth tube funnel-shaped, 3-6 mm long; tepals oblanceolate to elliptic, 15-35 x 6-12 mm.
