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.]
