Characteristics

Plants 120-350 mm high, stem simple or with 1 or 2 upright branches, sheathed at base by long, chestnut-brown cataphylls and a collar of fibres. Corm 12-20 mm diam., tunics of medium-textured fibres. Leaves usually 4 or 5, lower 3 or 4 with sword-shaped to falcate blades, ± 1/2 as long as stem and (2-)3-5 mm wide, uppermost leaf entirely sheathing, main veins and margins slightly to moderately thickened. Spike flexuose, erect, 2-ranked, mostly 6-12-flowered; bracts membranous, translucent, 4-5 mm long, outer with prominent central vein or secondary veins equally prominent, 3-lobed with central lobe largest or ± equally 3-lobed, inner slightly shorter than outer, 2-veined and 2-toothed. Flowers nodding with tepals held vertically, deep pink (sometimes called purple), white (sometimes edged with dark pink) at base of tepals, unscented; perianth tube filiform but expanded near mouth, 3-5 mm long; tepals spreading, oblong, (8-)10-14 x 4-8 mm. Stamens symmetrical in bud, becoming unilateral in open flower, straight, held horizontally at right angles to tepals; filaments inserted at mouth of tube, filiform, 2-3(-4) mm long, white; anthers oblong-linear, 2.5-4.0 mm long, yellow, dehiscing completely by longitudinal slits. Style dividing between base and lower 1/3 of filaments, style ± 2 mm long, branches tubular, strongly falcate, stigmatic apically, white. Flowering time: mid-Aug. to late Sept.
