Indigenous Endemic

Morphological description

Small, geophytic herb, 50-150 mm high. Rootstock a short, vertical, corm-like rhizome, 15 x 20(-25) mm; roots few, semisucculent. Leaves 3-6, erect to spreading, semiterete with a poorly defined double keel, 100-150 x 1.0-1.5 mm, bright green with a purplish membranous base; apex distinctly acute and hooked. Spathe valves 2, longest 4 mm, purplish brown, scariose at anthesis. Flower scape thin, reddish brown, especially in lower half, as long as or little shorter than leaves, carrying 2-4 flowers. Pedicels 7 mm long, greenish purple. Flowers regular, bisexual, facing upwards, 5.5-7.0 mm long, bell-shaped, white fading pink to magenta, lasting a single day. Perianth segments connate for 2 mm in lower half; outer segments flaring outward, spathulate, white at anthesis, pinkish towards tips, keeled with purplish tips, pale pink midvein on inside, 4.5 mm long, 2 mm wide in upper third; inner segments broadly oblong- ovate, spathulate segments shorter than outer segments, 1.5 mm wide in middle, greenish hyaline with faint green midvein. Staminal filaments 6, filaments facing outer perianth segments 3, thread-like, fused to edges of petaloid appendages of inner filaments for more than half their length; filaments facing inner perianth segments 3, originating at base of inner perianth segments, dilated into oblong retuse-erose petaloid wings on adaxial sides; 6 staminal filaments forming a cylindrical pseudocorona. Anthers bright yellow, sagittate, 0.3 x 1.5 mm, attached to tips of thread-like filaments and middle of petaloid wings of short filaments, slightly protruding above rim of pseudo-corona. Gynoecium: ovary 3-locular, obovate-triangular with rounded corners, 1 mm long, as long as coalescing base of perianth segments, shiny green; style filiform, exserted shortly beyond dehiscing anthers, 3 mm long, thin; stigma capitate, papillate. Capsule mitre-like when ripe, with dry perianth segments persisting at base. Seeds triangular-elongated, 2 mm long, black. From: Vosa, CG; van Wyk, AE; Siebert, SJ; Condy, GS. 2011.
