Taxon Profile     (Last Modified On 6/17/2016)
Description: Plants 100–180 mm high. Corm 10–14 mm diam., broadly obconic; tunics dark brown, rugose, basal rim with long, slender, spreading spines. Stem simple or 1–2-branched from base; stem round to slightly compressed. Leaves 1–3, lowermost basal and longest, straight to somewhat falcate, 80–160 mm long, sometimes exceeding flowers, 3.5–5.0 mm wide, strongly ribbed, sparsely woolly (rarely ± smooth), remaining leaves much smaller, resembling floral bracts. Inflorescences spikes of (5–)8–10 flowers, initially 2-ranked, becoming spiral; outer bract 10–15 mm long, acute, ± inflated, rounded, without keels, inner bract ± half as long, transparent with 2 green keels. Flowers white (pale yellow when dry), flushed red on reverse of tepals and tube, lower tepals with red blotch in lower 1/3 and paired, red lines near base running into throat (purple when dry); perianth tube mostly 45–56 mm long, ± uniformly wide throughout; tepals unequal, obovate and markedly narrowed in basal 2 mm, dorsal 16–18 × (7–)9–10 mm, lower tepals held ± horizontally, united basally for ± 1.5 mm, ± 15 × 5.5–6.5 mm. Stamens unilateral± erect; filaments ± 10 mm long, exserted 2–3 mm; anthers 4.5–5 mm, violet, pollen purple. Style dividing opposite anther tips, style branches ± 3.5 mm long, divided for half their length, recurved, white. Capsules and seeds unknown. Flowering time: late August to early October.
Country: South Africa
South African Province: Northern Cape
Distribution and ecology: restricted to the southern Kamiesberg in Northern Cape, from the flats around the Farm Doornkraal at ± 600 m and in the Langkloof at elevations of up to at least 950 m; in decomposed granitic soil and occasionally in granite outcrops.
Diagnosis: the broadly obconic corm with dark brown, rugose tunics spiny along the rim of Lapeirousia kamiesmontana are shared with L. dolomitica and L. lewisiana from which it is distinguished by white flowers with distinctive red markings on the lower tepals and a perianth tube mostly 45–60 mm long. The earlier-blooming L. lewisiana has dark red-purple to magenta flowers with white markings and a perianth tube (35–)40–48 mm long. The somewhat woolly indumentum on the basal leaf is also distinctive, a feature shared in the genus only with L. lewisiana The ranges of the two do not overlap and flowering times, even at the same elevation, are separated by at least two to three weeks, if not longer, in any particular year. L. kamiesmontana has been considered most closely related to L. lewisiana but that hypothesis has not been supported molecular studies.
Pollination: the form and colour of the long-tubed flowers of Lapeirousia kamiesmontana suggests pollination by long-proboscid flies but no insect visitors have been recorded for the species. The likely flies are long-proboscid species of horseflies, Philoliche spp.
