A glabrous or glabrescent, much-branched, sometimes almost divaricate, erect shrub, 2-6 dm high, with a woody taproot; branches ribbed-striate, often laxly puberulous when young; old stems up to 5 mm thick and strongly woody, nude, ash-grey. Leaves closely set on the upper branches, alternate, erecto-patent-spreading,3-20(-30) mm long, linear-filiform, 3-5-lobed above the middle with often spreading or recurved tips, or some or all entire; rachis and lobes 0.5-1 mm wide, somewhat flattened or subterete, punctate with im pressed glands, obtuse and mucronate; leaf-base often with short lateral lobes. Capitula sessile or shortly pedunculate, solitary, often somewhat nodding. Involucre shallowly cup-shaped-broadly campanulate, 5-10 mm wide. Involucral bracts ca 15-22, imbricated, lanceolate-ovate-oblong, subcoriaceous with membranous, somewhat glossy, whitish-pinkish margins and tips, with rounded convex or almost keeled back and obtuse tip; inner bracts up to 4-6 mm long and 2-3 mm wide, outer smaller. Receptacle obtusely conical-hemispherical, glabrous, somewhat tuberculate. Ray-florets 9-13, white. Tube somewhat compressed, elliptic-oblong, 0.5-1 mm long and wide, glandular. Lamina ± oblong, 3-6 mm long, 1.5-3 mm wide, 4(-5)-veined, ± reflexed after anthesis, marginal veins often with one lateral branch each, apex 2-3-toothed or-lobed, upper side colliculate, lower side smooth and sparsely glandular. Style terete with little swollen base; nectary short, indistinct; style branches 0.3-0.4 mm long, truncate. Disc hemispherical with ca 70-100 florets. Corolla tubular, yellow with sometimes purplish tips, 1.5-2.5 mm long. Tube thickish and spongy, ca 1 mm long. Limb narrow, not distinctly campanulate; lobes triangular-ovate, 0.3-0.6 mm long. Anthers 0.8-1.2 mm long inch the oblong subtruncate appendage. Endothecial cells elongate, with numerous thickenings on vertical walls. Filament collar distinct, of ± uniform, broadly rectangular-subquadratic cells. Style branches 0.2-0.4 mm long, truncate; nectary short and sometimes in distinct. Achenes 0.7-1 mm long, oblong, subquadrangular, 5-ribbed, glandular with broad sessile glands, abaxial side flattish and faintly striate with a myxogenic cell layer. Pappus obliquely cup-shaped, scarious, white, 0. 5-1.2 mm long, ± truncate or premorse, abaxially deeply or sometimes completely emarginate, occasionally deeply 3-5-lobed, rarely with an additional small adaxial scale (in ray florets). Pollen grains spheroidal, diameter ca 22 ? (incl. spinules). Exine at equator ca 8 ? thick. Supratectal spinules totally ca 36-40. Exine otherwise as in C. hilliardiae.
