Osteospermum norlindhianum J.C.Manning & Goldblatt

Tufted perennial from woody crown, 300-450 mm high, caudex producing a cluster of annual flowering stems; flowering stems suberect, laxly branched, 2-3 mm diam. at base, pubescent with mix of straggling, eglandular hairs and short, gland-tipped hairs, flushed purple at base. Leaves congested basally, lowermost subopposite with bases imbricate but not connate, becoming alternate distally as internodes lengthen, decreasing in size acropetally and ultimately grading into linear-subulate bracts, lower leaves oblanceolate, mostly 40-90 x 6-9 mm, leathery, sparsely to densely pubescent with mix of acute, eglandular hairs and gland-tipped hairs, adaxial surface ± asperulous, abaxial surface ± glandular-pubescent intermixed with scattered, straggling, eglandular hairs, these longer and denser along margins, blade tapering below into long, petiole-like base, midrib prominent abaxially, margins sparsely and weakly dentate, apiculate. Capitula heterogamous, radiate, ±20 mm diam., on slender, branched peduncles forming lax, compound corymbs, nodding in fruit; involucre shallowly campanulate, 7-8 mm diam.; involucral bracts 12-15, sub-uniseriate, lanceolate, 3.5-4.0 x 1.0-1.5 mm, acute, densely glandular-pubescent, with scarious margins 0.25-0.50 mm wide; receptacle flat, glabrous. Ray florets female-fertile, 8-10; tube sparsely glandular-pubescent, ±1 mm long; lamina spreading but recoiling in afternoon, narrowly elliptic, 4-veined, ±3 x as long as involucre, 9-10 x 3 mm, bright yellow, sometimes flushed reddish abaxially. Anthers vestigial, free, reduced to 4 subulate staminodes ±0.8 mm long, yellow. Ovary obovoid, 3-angled, ±2 mm long, densely glandu-lar-puberulous; style terete, branching ±0.5 mm above mouth of tube, branches narrowly elliptic-lanceolate, obtuse, ±1 mm long, yellow, lateral margins stigmatic. Achenes heteromorphic in some capitula, 3-winged or unwinged: winged achenes 10-12 x 7-8 mm, body turbinate, ±7 mm long, transversely ribbed and glandular-scabrid, with cylindrical, apical, trifenestrate airchamber, windows ovate, ±2.5 x 2.0 mm, wings translucent, 2-3 mm wide but sometimes one or two only partially developed; unwinged achenes 0-3, fusiform-rostrate, 10-12 x 1.5 mm, glandular-pubescent, body purplish, rostrum and stipe greenish. Disc florets functionally male, numerous; corolla narrowly funnel-shaped, ±3 mm long, yellow; tube glandular-hairy, ±2 mm long; lobes suberect, triangular, ±1 mm long. Anthers 2 mm long, yellow; base tailed, tails equalling filament collar; apical appendage ovate. Ovary ± terete, ±1.5 mm long, glandular-pubescent; style terete, on short stylopodium, shortly bifid, lobes deltoid, acutely papillate with basal fringe of longer trichomes.
