Characteristics

Plants 60-100 mm high, including flowers. Corm ± 7-8 mm diam., ± bell-shaped, usually 40-60 mm below ground; tunics dark brown, fairly smooth, basal margin lightly serrated with teeth directed downward. Stem usually branched, then from base, compressed and lightly 2-angled, angles smooth or lightly serrated. Leaves 3 to 6 (or more), lowermost usually conspicuously longer than others, ± twice as long as stem, linear, ascending to falcate, 2.0-3.5 mm wide, strongly ribbed, upper cauline leaves shorter, sometimes resembling bracts and not ribbed, usually subtending branches. Inflorescences 2-to 4-flowered spikes; outer bracts green, firm, 20-35 mm long, lanceolate, acute, slightly keeled, margins hyaline, those of lower flowers unifacial and ribbed distally; inner bracts forked at tips, transparent in centre, ± 1/2-2/3 as long as outer. Flowers zygomorphic, cream-to ivory-coloured, fading to dull pink, pink on outside of tepals and tube, lower tepals each marked with a small yellowish basal mark surrounded by a dark purple zone, usually with a small claw-like cusp at base of lowermost or all 3 lower tepals; perianth tube 30-35 mm long, widening and lightly curving outward near apex; tepals unequal, lanceolate and acute, dorsal largest, ± 20 x 7 mm, initially erect or arching forward over stamens later reflexed, upper lateral tepals slightly reflexed, lower three tepals united for ± 2 mm, ± 13 x 5 mm, held at right angles to tube, tilted at ± 30° below horizontal. Stamens unilateral, arcuate; filaments ± 9 mm long, reaching mouth of tube or exserted up to 2 mm; anthers contiguous, 3-5 mm long, mauve; pollen pale violet. Style dividing opposite middle of anthers; style branches ± 3 mm long, divided for ± 2/3 their length. Capsules oblong, 12-15 x ± 7 mm, apices of locules forming auriculate lobes decurrent on weakly developed locular ridges. Seeds globose, ± flattened or lobed at chalazal end, ± 1.6 mm diam., red-brown.
