Characteristics

Plants (40-)70-200 mm high. Corm globose, obliquely flattened toward base with crescent-shaped basal ridge ± as wide as corm, 7-15 mm diam., tunics splitting into fine parallel fibrils along ridge, sometimes forming fibrous neck above. Stem usually aerial, exserted up to 200 mm, very slender, almost wiry. Leaves 3 to 4, lowermost 2 basal, filiform and narrowly 4-grooved, 0.5-1.0 mm diam. Peduncles up to 3, semiterete, suberect or spreading in fruit; outer bracts green with narrow membranous margins, 8-15 mm long, finely striate (5 or 6 veins/mm), inner bracts with broad, membranous margins colourless or brown-flecked along edge. Flowers deep (rarely pale) pink, with short dark lines or small blotches in throat, cup golden-yellow, outer tepals streaked on reverse, rose-scented; perianth tube funnel-shaped, 4-6 mm long; tepals elliptic, 9-22 x 4-6 mm. Filaments 3-5 mm long, pilose at base or throughout, golden-yellow; anthers 3-4 mm long, pale yellow. Style dividing just below or just beyond anthers apices, branches ± 2 mm long, divided halfway. Capsules subglobose to ellipsoid, 5-8 mm long.

Plants sometimes up to 600 mm long. Stem extended above ground, very slender, often somewhat bent or flexuose, 100-250 mm long. Basal leaves usually slender, flaccid, less than 1 mm in diam., glabrous. Inner bracts sometimes brown-dotted on the largely colourless membranous margins. Flowers 15-30 mm long, magenta-pink, sometimes with small dark blotches in the throat, cup golden-yellow. Perianth segments elliptical, 9-22 x 4-6 mm. Filaments 3-4 mm, minutely pilose almost to the tops, widened in the middle, as long as the anthers. Style 7-10 mm; stigmas at or above the anther tips. Capsules globose or ellipsoid, on straight spreading peduncles.
Similar to R. schlechteri but with slender, elongate stem. Flowers magenta-pink with yellow cup, filaments swollen in middle.
