description: a. Callilepis laureola var. laureola
Erect, perennial herbs with tufts of annual stems from large underground rootstock, (280–) 300–600 mm high. Stems unbranched or sparsely branched, becoming pedunculoid upwards, ribbed, glabrous, with occasional hair, or sparsely to densely villous, often densely villous immediately below capitula, with tufts of hairs in leaf axils. Leaves sessile, lower opposite or subopposite, upwards alternate, sometimes alternate all along, mostly narrowly ovate to ovate, sometimes some upper narrowly elliptic, rarely some narrowly obovate, decreasing in size upwards and passing into peduncular bracts, (10–)15–60 × (3–)4–20(–30) mm, apex acuminate or attenuate, sometimes acute, base subcordate, rounded or obtuse, especially in lower leaves, or narrowly to broadly cuneate in upper leaves, margin sometimes whitish or paler than rest of blade, entire or sometimes in some leaves sparsely and minutely serrulate in upper part of leaf, rarely with single small tooth on each side in upper part, glabrous, with occasional hair or sparsely to more densely villous, blade glabrous, with occasional hair or sparsely to more densely villous, hairs sometimes concentrated along main veins on upper surface (Fig. 25B–D), 3(5)-veined from base. Capitula heterogamous, radiate, solitary. Involucre hemispherical, 15–30(–35) mm wide. Involucral bracts in (2)3 or 4 rows, subequal, inner grading into outer paleae; outer row linear, linear-triangular, narrowly triangular or (very) narrowly ovate, 5.0–13.5(–14.0) × (0.5–)0.8– 1.5(–2.5) mm, apex acute to (long) acuminate, margin sometimes very narrowly membranous in lower part, minutely pectinate or sometimes sparsely villous basally, surface glabrous or occasionally sparsely villous basally (overflow from peduncle); second row linear-triangular, narrowly triangular or (very) narrowly ovate or narrowly oblong, (4–)5–11(–13) × (0.8–)1.0– 2.5 mm, apex acute or (long) acuminate, margin sometimes (very) narrowly membranous in lower part, minutely pectinate or sometimes with few hairs in lower part, surface glabrous or occasionally with few hairs basally (overflow from peduncle); third row / ray paleae narrowly triangular, ovate or narrowly to very narrowly ovate, 5.5–10.0(–11.5) × 1.0–2.5(–2.8) mm, apex (long) acuminate, margin very narrowly or broadly (ray paleae) membranous in lower part and sometimes folded inwards (ray paleae) there, glabrous, with few (long) hairs in lower part or faintly pectinate, surface glabrous or with few hairs near base; fourth row/ray paleae narrowly ovate or ovate, rarely narrowly triangular, 6.0–9.0(–10.5) × 1.5–2.0(–2.5) mm, apex (long) acuminate, margin very narrowly membranous, glabrous or sparsely hairy in middle part or pectinate, sometimes folded inwards, surface glabrous, rarely with few hairs at base. Receptacle conical, paleate, paleae boat-shaped, (4.0–)4.5–8.0(–8.2) mm long with dark apex, 0.5–2.0(–2.5) mm long, back sometimes with narrow membranous wing. Ray florets zygomorphic, female, fertile, rarely some neuter in a capitulum, arranged in 1, 2 or 3 rows; corolla white, cream, creamy, cream-white, yellow, lemon-yellow, sulphur yellow or pale greenish yellow; tube (0.5–)1.0–3.0(–4.0) mm long, limb (8.5–)10.0– 19.0(–24.0) × (2.5–)4.0–7.0(–8.5) mm, unlobed or minutely 2- or 3-lobed; staminodes 0 to 4(5), (1.0–)1.5–2.0(–2.5) mm long, sometimes exserted. Styles 2.0–4.5(–6.0) mm long, exserted, bifurcate, lobes equal or sometimes unequal, rarely undivided, upper part below style branches sometimes cup-shaped; unbranched styles (2.8–)3.5(–4.0) mm long (seen in 5 specimens); style branches oblong or linear, 0.5–1.2 mm long; unlobed style branch 0.8–1.0(–1.2) mm long (seen in 5 specimens); apex obtuse, with broad marginal stigmatic areas, confluent in broad apical band or entire inner surface stigmatic. Ovaries obovate-trigonous, 2–5 mm long, those of second and third rows of ray florets laterally compressed similar to disc floret ovaries, glabrous. Ray cypselae (not often collected) usually obconical-trigonous, 5–7 × 2–3 mm (only seen in 4 specimens), those of second and third rows of ray florets obovate and laterally compressed, straw-coloured, glabrous, ribbed, each angle(margin) ending in a pappus awn. Ray pappus dimorphic, consisting of one long awn 2.5–5.0 mm long, (one)two shorter awns, 1.5–3.5 mm long (only one short awn in laterally compressed ovaries/cypselae of second and third row of ray florets), and few smaller obtuse or rarely acute, lacerated scales in between, 1(–2) mm long. Disc florets actinomorphic, bisexual, fertile, many; corolla purple, purplish, black, maroon, brown, brownish purple, tubular; tube (2.8–)3.0–4.0(–4.5) mm long, with parallel sides basally, between basal and upper part often with ring-like thickening and from there widening narrowly funnel-shaped upwards, 5-lobed; lobes narrowly ovate, (1.0–)1.5–2.0(–2.5) mm long, acute, recurved. Anthers 5, 1.5–2.0(–2.2) mm long, exserted, apical appendages narrowly ovate, 0.5–0.8(–1.0) mm long, bases caudate and calcarate, tails 0.5–1.0 mm long, ciliate. Styles (2.5–)3.0–5.0(–5.2) mm long, bifurcate, sometimes exserted but mostly hidden within anther ring; style branches oblong or linear, 0.8–1.5 mm long, apex (broadly) conical or (broadly) obtuse, with acute hairs outside at base of cone, with broad marginal stigmatic areas, confluent in broad apical band or entire inner surface stigmatic. Ovaries obovate, 2–5(–7) mm long, laterally compressed, glabrous. Disc cypselae asymmetrically obovate, (4.0–)5.5–6.0(–7.0) × 2.5– 3.0(–4.8) mm, laterally compressed, ribbed, glabrous, straw-coloured, with slight membranous wing on side of longest pappus awn and running up into it. Disc pappus dimorphic, consisting of one long awn, 2.5–4.5 mm long, one(two, three) shorter awn(-s), (1.5–)2.0– 3.5 mm long, and smaller, oblong to narrowly elliptic, obtuse, sometimes acute, scales 1(–2) mm long, with lacerate apices, between awns. Flowering time recorded throughout the year but with a peak from August to February. Figs 9A, 25B–D, 27, 28.
Diagnostic characters:— Callilepis laureola var. laureola can be distinguished by its mostly narrowly ovate to ovate, prominently 3-veined leaves with acuminate or attenuate, sometimes acute apex and subcordate, rounded or obtuse base, stems, leaf margins and leaf surfaces sparsely to more densely villous (Fig. 25B–D), rarely glabrous, solitary capitula with narrow, subequal involucral bracts, white, creamy or yellowish ray florets, purplish or blackish disc florets, and glabrous cypselae. The presence and density of hairs on the plants are variable, but hairs are usually present on some parts of the plants. Only in a few cases the plants are totally glabrous but they can immediately be recognised by their ovate leaves in contrast to the glabrous C. glabra where the leaves are narrowly elliptic.
Distribution:— Callilepis laureola var. laureola is near endemic to northern and eastern South Africa and is distributed from Limpopo, Mpumalanga, eSwatini, KwaZulu-Natal and the Eastern Cape (Fig. 29). Also present in Mozambique. According to Foden & Potter (2005), the Red List Status of C. laureola is Least Concern.
