Characteristics

Plants mostly 300-400 mm high, with 1 to 3(-5) branches from base. Corms 10-20 mm diam., tunics of fine, pale, netted fibres. Leaves 5 to 10 in a basal fan, narrowly sword-shaped, acuminate, reaching ± to base of spike, 10-20 mm wide, closely veined with prominent main vein. Spike suberect, ± straight, 2-to 5-flowered, initially 2-ranked but ultimately subsecund; bracts dry, crinkled, light translucent brown with darker streaks, without visible veins, outer 20-30 mm long, narrowly deltoid, entire, later upper margins lacerate, inner usually slightly shorter, forked apically. Flowers radially symmetric, bright orange-scarlet, yellow in centre broadly edged with dark red-brown, unscented; perianth tube funnel-shaped, 9-12 mm long, lower narrow part ± 4.5 mm; tepals subequal, broadly lanceolate-ovate, 25-35 mm, outer 15-20 mm wide, inner 13-16 wide. Stamens symmetrically arranged; filaments 6-7 mm long, closely surrounding style, yellow; anthers linear, 8-9 mm long, weakly diverging, pale yellow; pollen white. Style dividing opposite lower 1/3 of anthers, branches 2-3 mm long, expanded in distal 1/3, notched at apex. Capsules ± barrel-shaped, 6-7 mm long, showing outline of seeds. Seeds globose, glossy reddish brown, ± 2.0-2.5 mm diam., 4 to 8 per locule.

Herb 10–30 cm high. Corm 1–2 cm diam. Leaves 5–10, linear to oblanceolate, acute, 8–20 cm long, 5–15 (–18) mm wide. Scape unbranched. Spike flexuose, 2–6-flowered. Bracts lanceolate, acute, shallowly lacerate, 2.3–2.8 cm long. Flowers broadly funnel-shaped. Perianth tube c. 8 mm long, narrow at base, widened above, bright yellow; lobes oblanceolate to lanceolate, 2.5–3 cm long, c. 1 cm wide, orange to dark red with black sagittate mark at base. Stamens equilateral; filaments 6–7 mm long; anthers erect, c. 8 mm long, yellow. Style erect, not exceeding anthers; branches cuneate, 1–2 mm long, yellow. Fruit not seen. Bulbils few, in lower leaf axils only. [This description from Cooke (1986a: 56) requires revision, it possibly includes elements of Sparaxis pillansii L.Bolus, as material from Western Australia, e.g. specimen Royce 4371 (PERTH), was included in the S. tricolor treatment -Editor, 29 September 2020.]
Plants 10–40 cm. Corms tunicate; tunic with fine, whitish fibers. Leaves several, ± reaching base of spike. Spikes: spathes pale brown with darker brown streaks, subequal, dry, crinkled, outer with entire or lightly lacerate margins, inner forked apically. Tepals bright orange, yellow in center, with heart-shaped yellow mark in proximal 1/3, outlined distally with dark reddish brown band, lanceolate, subequal, 25–33 mm; perianth tube funnel-shaped, ca. 8 mm; stamens symmetrical; filaments contiguous, 6–7 mm; anthers yellow, linear, 8–9 mm; style slender, branching opposite anthers; branches 1–2 mm, expanded apically.
Tufted, grass-like, to 20 cm high. Corm c. 2 × 1.5-2 cm; tunic grey-brown, closely woven. Leaves to 20 × 0.6-1 cm reaching to c. level of lowest flowers in basal fan; cormils few in lowermost leaf-axils. Inflorescence a spike; spathe-valves 2-3 cm long, marked with minute red-brown flecks, entire or lacerate at tip. Flowers (1)-2-5, ± 4 cm long, 4-5 cm diam.; tube c. 1 cm long, enclosed by spathe-valves; lobes variously coloured from deep orange-red through scarlet-red to dark purple-red, internally all with a dark brown blotch above bright yellow tube.
