Characteristics

Plants 400-600 mm high, with glabrous cataphylls. Corm depressed-globose, 20-30 mm diam.; tunics firm-papery to leathery, fragmenting irregularly. Stem straight and erect, occasionally branched, slightly compressed. Leaves 5 or 6, lower 4 basal in a 2-ranked fan reaching to ± base of spike or occasionally somewhat longer, leathery, often puberulous, lanceolate or rarely almost linear, 14-20 mm wide, margins strongly thickened and hyaline, main vein not or barely distinguished from secondary veins, these also prominent but not hyaline, cauline leaves overlapping and uppermost inserted on middle of stem, largely sheathing and enclosing stem and sometimes base of spike. Spike straight and erect, 14-to 20(25)-flowered; bracts pale green and soft-textured, slightly inflated, outer (18-)25-37 mm long, slightly more than 2 internodes long, pleated in lower 1/2, dry toward apices and folded back, inner ± as long, lower margins fused around ovary. Flowers bluish grey to cream-coloured, minutely speckled with blue to red, more densely so along midline of upper tepals, lower lateral tepals yellow in lower half, unscented; perianth tube obliquely funnel-shaped, ± 16 mm long, lower cylindric part ± 8 mm long; tepals ovate-lanceolate, unequal, dorsal and upper laterals nearly equal, ± 28 x 17 mm, dorsal arching horizontally over stamens, lower laterals directed forward or curving outward toward apices, lower 3 tepals united for ± 2 mm, curving outward and downward from base, lower laterals ± 23 x 8.5 mm, lower median ± 25 x 11.5 mm. Filaments 11-12 mm long, exserted ± 4-5 mm from tube; anthers ± 12 mm long, mauve; pollen cream-coloured. Style dividing between base and middle of anthers, branches ± 6 mm long. Capsules oblong, 3-lobed and auriculate above, retuse, ± 25 mm long. Seeds oval to round, 6 x 5 mm long, broadly and evenly.
More
Flowers white to pale-blue or purple, usually densely speckled with minute purple to pink dots, these more crowded towards the midline of the tepals, the lower tepals each with a central yellow streak in the lower half; perianth tube 15–16 mm long, shortly exserted from the bracts, narrowly funnel-shaped; tepals 25–33 mm long, lanceolate, the uppermost larger than the others and arching over the stamens, the lower 3 tepals united for 2–3 mm, narrower below, curving downward throughout, usually slightly exceeding the uppermost when viewed in profile.
Foliage leaves 3–4 basal, longer than the others, reaching at least to the base of the spike, rarely shortly exceeding it, 10–15 mm wide, narrowly lanceolate (to linear), sometimes minutely pubescent, the margins thickened and hyaline, the midrib less so and some other veins equally prominent; the upper leaves deceasing progressively in size, the uppermost sometimes entirely sheathing.
Cormous, glabrous geophyte, up to 0.8 m high; without hairs. Leaves in a compact fan, shorter than spikes, acute with many fine close-set similar nerves, without prominent midrib. Flowers: in a 14-20-flowered spike; bracteole with 2 long teeth; anthers > 12 mm long, mauve; perianth white, speckled with purple or rarely plain white; Nov.-May.
Spike erect, distichous, 9–15-flowered; bracts green or somewhat dry and light-brown above, 2–3 cm long, usually imbricate, often 1.5(2) internodes long, clasping the stem below, apices curved outwards, the inner about as long as the outer and bifid with acuminate-setaceous apices.
Cormous herb, up to 0.8 m high. Plants glabrous. Leaves in a compact fan, acute with many fine close-set similar nerves. Spikes up to 25-flowered. Bracteole with 2 long teeth. Flowers white, speckled with purple or rarely plain white.
Corms 2.0–2.5 cm in diameter; tunics membranous to coarsely fibrous.
Style dividing near the anther apices, style branches c. 5 mm long.
Filaments 8–10 mm long, exserted for 3–4 mm; anthers 8–11 mm long.
Capsules c. 2.5 cm long, nearly ellipsoid.
Stem erect, rarely branched.
Plants 35–80 cm high.
