Taxon Profile     (Last Modified On 10/13/2016)
Description: Plants 300–600 mm high. Corm subglobose, 10–15 mm diam.; tunics of fine-textured fibres, sometimes with a papery neck. Stem inclined outward above uppermost sheath, usually unbranched or rarely with 1 branch from near middle. Leaves 4–8, linear, suberect in basal fan, ± 1/2 as long to as long stem, 80–200 × (1–)2–5 mm wide, acuminate, striate with main vein and submarginal vein thickened, intervening secondary vein slightly thickened, cauline leaves smaller and sheathing, uppermost often concealed by upper foliage leaf. Spike inclined, moderately dense or dense, secund, 2–10-flowered; bracts dry-membranous, translucent or straw, flushed dark reddish brown, speckled in upper half, outer 8–10, acute or 3-toothed, inner ± as long or shorter, bifid. Flowers zygomorphic, dark red drying to blackish purple; perianth tube obliquely funnel-shaped, 15–17 mm long, lower cylindric portion 3–6 mm long, widening above to 6–8 mm diam.; tepals obovate, dorsal larger, slightly hooded over anthers, often paler inside, upper laterals spreading, lower deflexed, upper tepals 10–14 × 5–10 mm, lower tepals 8–14 × 4–8 mm, each with quadrate callus near base, with median 2–4 mm high and yellow, lateralssmaller. Filaments unilateral, arcuate, 10–12 mm long, shortly exserted; anthers 5–7 mm long, often curved, dark. Style dividing opposite anthers, branches 3–4 mm long. Flowering time: December to January.
Country: South Africa
South African Province: Eastern Cape
Distribution and ecology: a local endemic from east of Butterworth in Eastern Cape, known from a few records between Kentani and Willowvale; in grassland.
Diagnosis: readily recognized by its stiff, linear leaves (1–)2–6 mm wide with the main vein, submarginal and intervening veins moderately thickened, the blades thus striate, and the dark red flowers drying blackish purple. The lower median tepals bears a yellow, axe-shaped callus and evidently smaller, dark calluses on the lower lateral tepals. It has a superficial resemblance to Tritonia disticha but this species has broader leaves, (5–)8–12(–20) mm wide and orange to red flowers without evident calluses on the lower tepals. It is more likely to be confused with T. drakensbergensis, which has similarly narrow (but not striate) leaves and red flowers with yellow calluses on the lower tepals but this is a high altitude species from basalt soils and the calluses are lower and triangular in shape.
