Characteristics

Plants 30-150 mm high. Corm obovoid to oblong, obliquely flattened toward base with high, crescent-shaped or ± flattened or wavy basal ridge, 10-15 x 5-10 mm, tunics splitting into fine parallel fibrils along ridge. Stem subterranean. Leaves 4 to 12, apparently all basal, often 2-ranked, lowermost arcuate or spreading, terete to oval in section and narrowly 4-grooved, 1.0-1.5 mm diam. Peduncles 1 to 4, rather short, up to 50 mm long, semiterete, initially arcuate in fruit but later erect; outer bracts submembranous or greenish in upper half, finely rust-or brown-speckled, finely and widely striate (3 to 5 veins/mm), with colourless or brown-spotted membranous margins, 6-10 mm long, inner bracts membranous or somewhat herbaceous in centre near tip with wide, prominently brown-spotted or-blotched membranous margins. Flowers pale mauve to lilac or rarely white, with greenish yellow cup, usually with violet circle in throat, outer tepals greenish or mottled on reverse; perianth tube funnel-shaped, 1.5-3.5 mm long; tepals elliptic, 4-9 x 1.5-2.5 mm. Filaments 2-4 mm long, glabrescent; anthers 1.5-2.0 mm long, pale yellow. Style dividing near tops of anthers, branches ± 1 mm long, divided. Capsules ellipsoid, 9-15 mm long.

Plants small, 60-200 mm long. Corm usually somewhat elongated vertically, with a high crescent-shaped basal ridge. Stem short, hidden. Leaves basal, often distichous, filiform to compressed cylindrical, 60-200 x 0.5-1.5 mm, often arcuate, grooves narrow. Bracts submembranous or greenish upwards; inner bract almost wholly membranous, with wide, usually brown-spotted membranous margins. Flowers 7-15 mm long, pale mauve or lilac, rarely whitish, often with a violet circle in the throat, cup greenish yellow, outer segments greenish or mottled on the backs. Perianth tube to 3.5 long; segments 4-9 x c. 2 mm. Filaments 2-4 mm; anthers 1.5-2 mm. Style 4-6 mm. Capsules ellipsoid, up to 15 mm long, on arcuate peduncles which straighten later.
Corm with obliquely flattened base; tunic split into fibres at base, extended as fibrous neck at apex. Leaves several, basal, 6–20 cm long, 0.5–1.2 mm wide, almost terete. Stem absent. Scapes 2–5 cm long. Outer bract ovate, 6–10 mm long, herbaceous with scarious margin, often brown-blotched; inner bract 5–9 mm long, scarious, brown-blotched. Perianth tube 2–3 mm long, dull yellow; lobes elliptic, obtuse, 5–9 mm long, pale pink to lilac; sepals greenish outside. Filaments 2–4 mm long, glabrescent; anthers 1.5–2 mm long. Style 4–6 mm long; stigmas hardly exceeding anthers. Capsule cylindrical to obloid, 1–1.5 cm long, on decurved scapes which straighten at maturity.
Perennial herb, geophyte, 0.06-0.20 m; corm obliquely flattened with spathulate basal ridge; stem hidden by leaf bases. Leaves several, basal, narrowly 4-grooved, filiform. Bracts submembranous, or greenish above, ± ovate, margins often brown-speckled, membranous. Flowers 1-4, pale mauve with yellowish cup; perianth tube 1.5-3.5 mm long; tepals 4-9 mm long, elliptical, obtuse. Stamens erect; filaments 2-4 mm long, glabrescent; anthers 1.5-2.0 mm long, pale yellow. Style 4-6 mm long; stigma 1 mm long. Flowering time July-Sept. Capsule ellipsoid.
Cormous geophyte, 30-60 mm tall, corm with a spathulate basal projection. Basal leaves several. Flowers tiny, up to 15 mm long, pale blue-mauve with yellowish cup, anthers ± 2 mm long, exserted from cup, inner bracts conspicuously spotted with brown.
Cormous geophyte, 3-6 cm, corm with a spathulate basal projection, basal ridge fibrous. Basal leaves several. Flowers tiny, to 15 mm long, pale mauve with yellowish cup, anthers ± 2 mm, inner bracts conspicuously spotted with brown.
