Taxon Profile     (Last Modified On 7/5/2016)
Description: Plants mostly 150–300 mm high, excluding leaf. Corm 10–20 mm diam.; tunics of medium to coarse, dark brown fibres. Stem usually with 3–6 branches held close to main axis on short stalks or ± sessile, sheathing leaves 30–60 mm long, dry, papery, brown, often lacerated. Foliage leaf solitary, usually absent or emergent at flowering, basal, ultimately up to 500 mm long or longer, terete, ribbed, ± 1.5 mm diam., becoming dry and broken before flowering. Rhipidial spathes dry, papery, rarely green near base, apices speckled darker brown, sometimes lacerate, attenuate; inner 25–40 mm long; outer ± 2/3 as long. Flowers fugaceous, pale blue-mauve, limbs of all tepals with yellow to orange nectar guides at bases; outer tepals obovate to lanceolate, 20–24 × 5–8 mm, claws slightly shorter than limbs, ascending, narrow; inner tepals 16–18 × ± 7 mm, lanceolate. Filaments 3–4 mm long united in lower 1/3; anthers ± 5 mm long, yellow. Ovary narrowly ellipsoid, ± 4.5 mm long; style branches 7–8 mm long, crests vestigial, shorter than stigma lobes. Capsules ± club-shaped, ± 10 mm long Seeds angular. Chromosome number 2n = 12. Flowering time: August to September (in November in tropical Africa).
Country: South Africa, Tanzania, Malawi
South African Province: Mpumalanga
Distribution and ecology: recorded only once in southern Africa, in Mpumalanga, otherwise occurring in Malawi and southern Tanzania; in dry grassland, blooming early in the season, usually before the first rains.
Diagnosis: virtually identical to the relatively common Moraea stricta in vegetative features and life history, M. thomsonii is distinguished only by the flowers. The blue-mauve tepals have nectar guides on both the outer and inner tepal limbs and the inner tepals, ± 7 mm wide, are broader than in M. stricta. The style branches are poorly developed and have vestigial crests shorter than the stigma lobes. In M. stricta the style crests are 3–4 mm long and held erect above the nectar guides and the inner tepals are only 3–4 mm wide. As in M. stricta, the leaf is terete, usually dry and broken at flowering time and the sheathing leaves and spathes are more or less dry.
