Taxon Profile     (Last Modified On 7/15/2016)
Description: Plants 180–350 mm high. Corm 12–18 mm diam.; tunics of wiry, black fibres. Stem abruptly flexed outward above sheath of foliage leaf, simple or few-branched, branches also flexed outward, bearing attenuate sheathing leaves 20–40 mm long. Foliage leaf solitary, inserted well above ground, channelled, exceeding stem, usually trailing distally, 4–10 mm wide. Rhipidial spathes attenuate, inner 50–80 mm long, outer ± 1/2 as long. Flowers long-lived, pale yellow or salmon pink, outer tepals limbs usually with deep yellow nectar guides at bases edged green, spreading, claws suberect, forming a narrow cup ± 12 mm deep, including filaments and anthers, ± 10 mm wide at mouth; outer tepals ± obovate, (25–)30–35 × 10–12 mm, claws 12–15 mm long, often papillate near bases, inner tepals 24–30 × 10 mm. Filaments united in a cylindric column 6–7 mm long, lightly pubescent in lower 1/2; anthers 5–6 mm long, slightly diverging above, yellow, pollen yellow. Ovary cylindric, (10–)14–19 mm long, often partly included; style branches (5–)6 mm long, diverging slightly and reaching anther tips, stigma lobe arched over anther tips, crests ± 1 mm long, erect to incurved. Capsules cylindric, (21–)30–40 mm long, short rounded beak ± 1 mm long. Seeds angular. Chromosome number 2n = 24. Flowering time: late June–early September.
Country: South Africa
South African Province: Western Cape
Distribution and ecology: locally common in the southwestern corner of Western Cape, from Cape Peninsula east to Bot River and north to Bain’s Kloof; mostly on sandy ground and flowering well in the years following a fire or when the ground is cleared.
Diagnosis: Moraea collina is recognized by the single leaf inserted on the stem well above ground, the stem flexed above the sheath of the foliage leaf, and yellow or pink flowers with the tepal claws forming a narrow cup including both filaments and anthers. The capsules are unusually long, even for sect. Homeria, typically 30–40 mm long and have a short blunt beak about 1 mm long. It is often difficult to distinguish in herbaria from several other solitary-leaved species of sect. Homeria, in particular M. minor and M. flaccida. In M. minor the shorter anthers are 3–5 mm long, the style branches are 5–6 mm long and divide 2–3 mm above the anther bases: in addition the shorter ovary up to 10 mm long and capsules 18–28 mm long separate the two. In the taller, more robust M. flaccida, the tepals, 35–40 mm long, have claws that diverge to form a wide cup and the elongate capsules, typically 30–55 mm long, have an acute beak ± 2 mm long.
General Notes: natural hybrids between Moraea collina and M. flaccida have been recorded from the Cape Peninsula. Because M. flaccida is hexaploid, 2n = 36 in this area (elsewhere sometimes tetraploid) and M. collina consistently tetraploid, 2n = 24, the resulting pentaploid hybrid with 2n (5x) = 30 is sterile.
