Characteristics

An erect much-branched shrub, 0.5-3 m tall, usually dense and rounded, glabrous throughout; branches erect, straight and fairly slender, leafy in the upper parts, becoming nude and marked with small triangular leaf-scars; cortex light or greyish brown, somewhat striate. Leaves erecto-patent-spreading, closely set, linear, 1-4 cm long, 1-2.5 mm wide, tapering to the base, flat and rather thin, herbaceous, entire or sometimes 2-3-lobed, green, with a distinct narrow midvein, acute and finely mucronate. Peduncles terminal, up to 12 together in an umbel-like arrangement, 1-5 cm long, c. 0.5 mm wide, thickened below the involucre, terete, faintly striate. Involucre campanulate-cyathiform, widening with ± straight sides from a narrow truncate base, 4-7 mm high, 4-7 mm in diam. above. Involucral bracts uniseriate, 9-14, much connate (to c. 3/4-4/5), light brown, with many, usually dark veins, somewhat coriaceous; the free parts ± deltoid, 1-2 mm long, basally with slightly overlapping margins, acute, with puberulous margins and tips. Receptacle distinctly convex, alveolate. Ray-florets 8-13, yellow. Tube 1.5-3 mm long, (narrowly) cylindrical. Lamina lorate or narrowly oblong, 8-12 mm long, 2-3.5 mm wide, 4-veined. Style terete with 0.6-1 mm long obtuse branches. Disc-florets c. 25-40. Corolla 4-5 mm long. Tube 1.5-2 mm long, cylindrical. Limb narrowly campanulate, 2.5-3 mm long; lobes narrowly triangular, 1-1.5 mm long, with subcucullate papillate tips. Anthers 1.5-2 mm long incl. the ovate obtuse appendage. Style terete with somewhat swollen base; stylophore distinct, brown; style branches 0.5-0.8 mm long with somewhat convex tips and very short sweeping-hairs. Pappus bristles few, 1.5-2 mm long, erect, white, very shortly barbellate. Achenes (oblanceolate-)narrowly oblong, somewhat compressed, triquetrous, or angular, 2.5-3.5 mm long, 0.8-1 mm wide, glabrous, light brown, faintly or indistinctly ribbed.
