Characteristics

Plants 500-900 mm high, stem sheathed below by membranous cataphylls, usually 2-3-branched, branches held at right angles to main axis, ascending distally, subtended by short, acute bracts and prophylls. Corm globose, 7-12 mm diam., tunics of medium-textured fibres, often with cormlets at base. Leaves 3 or 4, lower 2 or 3 with sublinear to narrowly sword-shaped blades, ± 1/2 as long as stem, 4-8 mm wide, main vein moderately thickened, uppermost leaf sheathing lower half of stem. Spike flexuose, 7-16-flowered, lateral spikes with fewer flowers; bracts membranous, translucent, 4.5-7.0 mm long, outer with 3 prominent, purple veins, 3-or 5-toothed, inner 2-veined and 2-toothed. Flowers zygomorphic, half nodding, pink, white to yellow edged deep pink at tepal bases, sweetly scented, perianth tube filiform, ± 5 mm long, expanded in upper 0.5 mm, tepals subequal, ovate, ± obtuse, 9-12 x ± 5 mm. Stamens unilateral, ± horizontal, inserted at mouth of filiform part of tube, filaments ± 3 mm long, filiform below, curved at right angles in upper 1 mm and becoming flattened and as wide as anthers, anthers ± 3 mm long, oblong, yellow, thecae acute and recurved near base, dehiscing incompletely from base. Style dividing at base of filaments, style branches ± 2.5 mm long, tubular, falcate, bifid at apex, stigmatic apically. Flowering time: late-Aug.-mid Sept.
