Taxon Profile     (Last Modified On 10/18/2016)
Description: Plants mostly 300–500 mm high. Corm subglobose, 15–30 mm diam., sometimes deep-seated; tunics of fine -textured fibres, extending into a thick, fibrous collar. Stem simple or with up to 2 suberect or weakly spreading branches. Leaves 5–8, ± erect, firm, compressed-cylindric or ± terete, (150–)200–300(–600) × 1–2(–3) mm, acute, striate with translucent veins when dry but without evident thickened main vein, sometimes as long as stem, cauline leaves dry and clasping, bract-like. Spike erect or arching, rather lax, (3–)6–10-flowered; bracts dry and papery, pale and translucent below and brown speckled dark brown at tips, outer (6–)10–15(–18) mm long, obtuse or ± 3-toothed with median tooth sometimes reduced, inner subequal, bifid. Flowers weakly zygomorphic, nodding, inverted, white to cream or pink to pale pink to rose-pink, darkly veined, unscented; perianth tube cylindric, curving outward, (20–)30–45(–55) mm long, slender, widening in upper 6–8 mm to 5–7 mm diam.; tepals subequal or outer, especially dorsal, wider, spreading, oblong to oblanceolate, (15–)20–25(–30) × (5–)7–10 mm but dorsal 8–14 mm wide, without calluses. Filaments unilateral, ± horizontal, (8–)15–20(–25) long, exserted; anthers 5–10 mm long, facing upward through inversion of flower, purple or cream; pollen violet or cream-white. Style dividing opposite upper 1/2 of anthers, branches 3–5 mm long. Capsules obovoid, 10–12 mm long. Flowering time: October to early December.
Country: South Africa
South African Province: Eastern Cape, Western Cape
Distribution and ecology: restricted to the central and eastern Little Karoo, from Ladismith in Western Cape to the upper Long Kloof east of Avontuur in Eastern Cape; on stony lower slopes, mainly on clay and flowering best after fire or clearing.
Diagnosis:

readily recognized among the long-tubed species of Tritonia by its slender, straight leaves, terete to elliptic in secion without an evident main vein and its nodding flowers with almost symmetrical, salver-shaped perianth with a slender, curved tube and tilted backward so that the anthers face upwards. The long-tubed species of sect. Pectinatae have plane leaves with a thickened main vein and zygomorphic, bilabiate flowers facing outward, with arcuate stamens held under the arching to horizontal dorsal tepal.

Populations from the southern foothills of the Swartberg between Calitzdorp and De Rust typically have pale to rose-pink but sometimes white flowers with slightly shorter perianth tubes and sometimes smaller tepals than the typical form. Treated as subsp. lilacina, they may represent a local pollination ecotype or a poorly diffentiated species. Typical subsp. bakeri also occurs in this area.
