Characteristics

Plants 250-350 mm high, stem unbranched, base sheathed by membranous to ± dry, brown cataphylls. Corm 9-18 mm diam., tunics of fine fibres extending upward as a collar. Leaves 2, lower 1 ± basal, upper 1 sheathing the stem in lower 1/2 to 2/3, free distally for up to 100 mm, blades linear, (0.5-)1.0-1.5(-2.0) mm wide, margins and midrib lightly thickened, hyaline when dry. Spike erect, ± straight, (1-)2-4(-6)-flowered; bracts membranous, translucent, sometimes suffused with purple distally, outer 5-7 mm long, prominently 3-veined and usually with secondary veins evident, acutely 3-cuspidate, sometimes central cusp smaller, inner ± as long as outer or slightly longer, 2-veined and 2-cuspidate. Flowers rotate, pale mauve-pink; perianth tube filiform, 3-4 mm long, clasping style; tepals spreading, ovate-elliptic, 12-15 x 4-6 mm. Stamens symmetrically arranged, erect; filaments inserted at mouth of tube, linear, straight, 0.6-1.8(-2.5) mm long, ± pale pink; anthers oblong, 2.0-2.6 mm long, erect, yellow, thecae slightly recurved basally and acute, dehiscing completely from base by longitudinal slits. Style dividing at or shortly above base of filaments, branches ± straight and diverging to slightly arched, 2-5 mm long, usually longer than stamens, filiform-involute, stigmatic and sometimes forked at apex, pale pink. Flowering time: mostly late Jul.-early Sept., occasionally later.
