Taxon Profile     (Last Modified On 7/15/2016)
Description: Plants 180–300 mm high. Corm 10–15 mm diam.; tunics of coarse, black fibres. Stem usually several-branched, bearing attenuate sheathing leaves 40–60 mm long. Foliage leaf solitary, inserted at or near ground level, linear, channelled, exceeding stem, often trailing distally, 3–7 mm wide. Rhipidial spathes attenuate, inner 70–100 mm long at flowering, much elongating after flowering and enclosing developing capsules, outer initally ± 1/2 as long as outer. Flowers long-lived, yellow or pink to orange with yellow center, sometimes with large dark green blotches on outer or both tepal whorls, tepals weakly divided into claws in lower half, but lower halves forming an open cup and upper halves ± spreading, heavily and sweetly scented; outer tepals 32–52 × 13–18 mm long, often pandurate or spathulate, widest in upper 1/3; inner tepals 30–50 × 8–15 mm. Filaments united in a column tapering from wider base, 6–8 mm long, pubescent in lower 2/3; anthers (8–)10–13 mm long, diverging, usually shorter than style branches, occasionally reaching or exceeding stigma lobes, yellow; pollen yellow. Ovary ± cylindric, ± 18 mm long, included or half exserted; style branches diverging, 6–10 mm long, crests erect to incurved, ± 1 mm long. Capsules initially cylindric, 25–30 mm long, included. Seeds angular. Chromosome number 2n = 12. Flowering time: late August and September.
Country: South Africa
South African Province: Western Cape
Distribution and ecology: endemic to the Caledon District of Western Cape and extending from near Villiersdorp and Bot River in the west to Caledon and Akkedisberg Kloof near Stanford in the east; on heavy clay soils in renosterveld.
Diagnosis: large-flowered Moraea comptonii is distinguished by the fiddle-shaped to spathulate tepals weakly divided into claw and limb with the lower halves forming an open cup and upper halves spreading. The flowers are particularly strongly and sweetly scented and either entirely yellow, or salmon-pink to orange with a yellow cup, often with dark green markings in the lower third. Like its close relative M. elegans plants have a single leaf, a partly to fully included ovary and the inner rhipidial spathes become enlarged to enclose the developing capsules. Also like M. elegans, the filaments are fully united in a column tapering from wide base but the anthers are usually shorter than the style branches in contrast to M. elegans, in which the anthers exceed the style branches. Another difference between the two is that the tepals of M. elegans are more or less ovate, widest in the lower third, and the tepal markings, confined to the outer tepals are in the upper third whereas tepals of M. comptonii are widest in the distal third and are either unmarked or have markings at the bases of the tepal limbs of both whorls. Both species have a pollination system using hopliine beetles, various flies and large-bodied bees, the dark markings serving to attract hopliines and the scent the flies and bees.
