Taxon Profile     (Last Modified On 7/5/2016)
Description: Plants small, 50–180(–250) mm high. Corm 10–15 mm diam.; tunics of pale, netted fibres. Stems usually ranched, either very short with nodes condensed, or elongated, sheathing leaves 25–35 mm long. Foliage leaves 2 or 1, linear, channelled, much longer than stem, 2–3 mm wide, margins straight; upper nodes with sheathing leaves ± as long as spathes. Rhipidial spathes membranous with prominent veins, becoming dry and transparent at flowering, inner 20–35(–40) mm long, outer slightly shorter. Flowers fugaceous, small, pale blue-mauve (rarely white), outer tepal limbs with white nectar guides edged orange distally, half reflexed; outer tepals12–18 × 5–9 mm, claws as long or slightly shorter than limbs; inner tepals12–16 mm long, limbs half reflexed. Filaments 3.5–6.0 mm long, united in lower 1/3 to 1/2; anthers2.5–4.0 mm long. Ovary ± cylindric, included, 16–23 mm long, fertile part ± 6 mm long; style branches4–7 mm long, diverging, crests 4–7 mm long, erect. Capsules ellipsoid, ± 10 mm long. Seeds dark brown, angular. Chromosome number 2n = 12. Flowering time: late spring, September–early November; opening 12:00–13:00 and collapsing after 17:00.
Country: South Africa
South African Province: Eastern Cape, Northern Cape, Western Cape
Distribution and ecology: widespread in the southern African winter rainfall area and extending from the Kamiesberg of central Namaqualand in Northern Cape south and east through Western Cape to Grahamstown in Eastern Cape, evidently absent from the south coast between Mossel Bay and Port Elizabeth; weedy and adventive, it often occurs in waste places, trampled sites, roadsides and even lawns in a variety of soils. It is naturalized in Australia.
Diagnosis: Moraea setifolia is readily distinguished in sect. Gynandriris by its low stature and small flowers. The blue-mauve flowers have orange and white nectar guides on the outer tepals, 12–18 mm long, and the limbs of both outer and inner tepals are half reflexed. The small flower size is reflected in the short filaments 3.5–6.0 mm long and short anthers up to 4 mm long. The flowers open between noon and 13:00 p.m. and fade shortly before sunset. Several populations examined for chromosome number are diploid, 2n = 12, plants have been found in the greenhouse to be reproductively self-compatible and autogamous. They thus produce ample seed wherever they occur. This mode of reproduction is unexpected in Moraea but explains its success as a weed.
