Characteristics

Much-branched shrub up to 1.7 m high; branches patent, leafy, minutely glandular-pubescent when young and flushed purple, later subglabrous. Leaves alternate, sessile, rigid, oblanceolate in outline, (20-)25-40(-50) x 8-20 mm, apex excurrent in yellowish spine 1-2 mm long, base scarcely narrowed, semi-amplexicaul, blade pinnatifid, 2-or 3-jugate, with smaller, deflexed lobe in distal axil of primary divisions, lobes triangular to narrowly triangular, shorter than, or as long as, width of undivided portion, excurrent in spine similar to apical spine and with smaller, antrose spines along margins, minutely glandular-pubescent on both surfaces but adaxial surface glabrescent and shining, with some cobwebby hairs in axils. Capitula 1-3 in shortly pedunculate corymbs at branch tips, radiate, 40-55 mm across expanded rays; florets yellow. Involucral bracts 3-or 4-seriate, basally connate in involucre ± 4 mm deep, patent-reflexed, ovate-lanceolate, excurrent in yellowish spine 2-3 mm long, margins with 2 or 3 pairs of patent spines similar to apical spine, sparsely and minutely glandular-pubescent, glabrescent, outer mostly 5-8 x 2-3 mm, median 10-12 x 3-4 mm, inner narrowly lanceolate, 6-8 x 1.5-2.0 mm. Receptacle deeply alveolate, margins irregularly fimbriate with straw-like spinules 1-2 mm long. Ray florets 12-14, neuter, tube ± 2.5 mm long, glandular-pubescent, limb oblanceolate, 18-25 x 4-5 mm. Disc corollas funnel-shaped, densely glandular-pubescent on tube and more sparsely along lobe margins, 8-9 mm long, tube ± 5 mm long, lobes erect, lanceolate, ± 3 mm long; anthers tailed with lanceolate apical appendage, ± 4.5 mm long; endothecial cells with inner periclinal wall reinforcements displaced towards the connective. Pappus scales uniseriate, ± 20, oblong-ovate, obtuse-truncate, denticulate, connate below, ± 0.3 x 0.2 mm. Immature cypselae obovoid, 2-3 x 1 mm, angled, densely antrorsely pubescent with short, twin hairs. Pollen lophate.
