Characteristics

Deciduous shrub 0.15-4 m high, usually leafless when flowering; rootstock woody; stems green and shortly pubescent with T-shaped hairs, becoming purplish grey with pale lenticels.. Leaves appearing after the flowers, petiolate, narrowly elliptic to obovate, to 8.5 cm long, to 3 cm wide, base cuneate, margins subentire or distally slightly serrate, apex acute or obtuse, subglabrous above, sparsely pubescent but glabrescent beneath; petiole 0.2-1 cm long.. Capitula in numerous corymbiform cymes, on numerous abbreviated shoots axillary to previous year’s leaves; involucre obconic, 3-6 mm long; phyllaries in few series, with raised purple midrib, elliptic or lanceolate, rounded and mucronate or obtuse, scarious, thinly pubescent where exposed and ciliate and densely glandular distally, becoming caducous, 2.7-5 mm long.. Florets 9-17 per capitulum; corolla purple or mauve, 6-8 mm long, lobes 1.5 mm long, glabrous.. Achenes tapering to base, 3-4 mm long, 8-10-ribbed, puberulous and glandular; outer pappus of scale-like setae 0.8 mm long, inner pappus white, 5-8 mm long.. Fig. 41/1-3.
More
Leaves usually appearing after the flowers, petiolate; petiole 2–10 mm. long, pubescent; lamina eventually up to c. 8.5 x 3 cm., narrowly elliptic to obovate-oblanceolate, apex acute to obtuse, base narrowly cuneate, margins subentire to subserrate towards the apex, sometimes ± revolute, thinly coriaceous, upper surface glabrescent, lower surface ± sparsely appressed-pubescent, or both surfaces glabrous, hairs short-stalked T-shaped; nervation finely reticulate and ± raised on both surfaces.
Phyllaries few-seriate, becoming caducous, scarious, thinly pubescent where exposed, or glabrescent, finely ciliate and densely glandular apically, midrib ± fleshy raised and purple towards the apex, margins narrowly hyaline; the outer phyllaries from c. 1 mm. long, the inner to c. 5 mm. long, narrowly oblong-elliptic, ± rounded and mucronate at the apex.
Capitula borne on numerous ± abbreviated lateral shoots; shoots 1–5 cm. long, bracteate, with 1–7 capitula racemosely to subpaniculately arranged, or capitula more laxly arranged in large diffuse panicles with capitula often scorpioidly cymose on the synflorescence branches, stalks 0.3–3 cm. long.
Stems and branches green and angular when young, becoming purplish-grey and subterete with pale prominent lenticels; branches ascending, densely appressed-pubescent especially on young shoots, soon glabrescent, sometimes tomentellous; hairs short-stalked T-shaped.
Achenes 3–4 mm. long, almost equalling involucre in length when mature, tapering to base, 6–8-ribbed, uniformly puberulous and glandular; outer pappus of short, barbellate, scale-like setae, inner oflong-exserted, whitish, barbellate setae 5–7 mm. long.
An erect spreading laxly branched subshrub or shrub, 0.15–4 m. tall, from a woody rootstock, usually leafless at flowering time.
Florets 9–12(17) per capitulum; corollas purple or mauve, paler below, 6–8 mm. long, widening towards the apex.
Involucres 3–6 mm. long, obconic to broadly cup-shaped, later spreading.
