Taxon Profile     (Last Modified On 7/22/2016)
Description : Plants 150–500 mm high. Corm 25–60 mm diam.; tunics of densely matted fibres, with long collar. Stem flexed outward at ground level and then stifflyerect or inclined, unbranched, (1.5)2–3 mm diam. Basal leaves 4 or 5, dry and fragmented at flowering, in a basal fan, blades linear-lanceolate, 100–220 × 4–8 mm, acuminate, with 3 or 4 veins, not narrowed to a pseudopetiole below, firm-textured; cauline leaves 2 or 3, lowermost subulate and concealed in collar, uppermost vestigial and scale-like. Spike moderately densely ± 12–40-flowered, 150–400 mm long; bracts dry and brown, cartilaginous with membranous margins, oblong or ovate-oblong, 7–13 mm long, conspicuously apiculate, inner slightly longer. Flowers zygomorphic, dull dingy pink with dark reddish veins, unscented; perianth tube narrowly funnel-shaped, 6–11 mm long, tepals unequal, dorsal slightly larger, arched over atamans, oblanceolate-spathulate, clawed in lower 2/3, 20–25 × 3–4 mm, obtuse, other tepals suberecet and recurved distally, 15–18 × 2.5–4 mm, upper laterals connate to lower laterals for ± 1 mm and lower 3 tepals joined at base for 3–5 mm. Filaments arcuate, later suberect, 13–16 mm long; anthers 6–7 mm long, yellow with small apiculus up to 1 mm long. Style 18–23 mm long, dividing opposite middle of anthers, branches ± 2 mm long. Capsules ovoid to subglobose, inflated, 25–35 × 10–15 mm. Seeds up to 10 mm long, winged on angles. Flowering time: (Jan.–)Mar.–Apr.
Country : South Africa
South African Province : Western Cape
Distribution and ecology : a narrow endemic of Western Cape, known from a few populations between Gouda and Paarl, with a single outlying collection from the southern foot of the Riviersonderend Mts near Greyton; on hard gravelly or stony slopes in open fynbos or transitional fynbos-renosterveld.
Diagnosis : distinguished from other species with similar, relatively small, pink flowers with narrow tepals, by the stiff stems, mostly 2–3 mm diam., bearing numerous dingy or brownish pink flowers from near the base in a long spike much longer than the non-flowering part of the stem, and by the conspicuously apiculate bracts hard and cartilaginous at flowering time. The leaves are dry and fragmented at flowering time although the leaves from, the next season may be emergent. The species can be confused with T. dodii, which has similar flowers but much fewer, in a short spike much shorter than the non-flowering part of the stem, and typically obtuse or acute, rarely shortly apiculate, bracts. Populations from the Boland have a perianth tube 6–8 mm long but the isolated population from near Greyon has a slightly longer tube 10–11 mm long and was collected in flower in January and February.
Pollination : the flowers are pollinated by honey bees and long tongued bees in the genus Amegilla (Anthophoridae).
