Characteristics

An erect much-branched shrub or shrublet, 1.5-9 dm high; branch-lets ascending or somewhat divaricate (often many short), leafy and powdery-tomentose when young; older branches nude, glabrate; cortex rough and irregular with remains of leaf-and peduncle-bases, mostly grey or blackish, sometimes with lighter coloured striae. Leaves moderately close-set on the young branches and crowded (3-5) together on brachyblasts, ± erecto-patent, flat or flattened, spathulate or cuneate and somewhat flabelliform, 3-7(-9)-toothed or-lobed at the truncate-rounded apex, sometimes digitately 3-5-lobed from or above the middle (with linear and thickish lobes and rachis), densely canescent-tomentose, especially when young, (0.5-)1-4 cm long, (0.3-)0.5-1.5(-2) cm wide at the apex, tapering to c. 1-2 mm wide near the base; leaf lobes 0.5-13 mm long, deltoid or ovate-linear, 1-3(-4) mm wide, obtuse, sometimes short-mucro-nate; leaf-base dilated, somewhat decurrent, minutely arachnose in the axil. Peduncles lateral in the upper leaf-axils and on the brachyblasts, erect or ascending, (2-)5-25 cm long, 0.5-1.2 mm wide, glabrous, striate. Involucre widely cupshaped-hemispherical, (5-)8-15 mm in diam. Involucral bracts 8-16, subuniseriate-subbiseriate, connate at the base only, elliptic-ovate-narrowly oblong-lanceolate, 5-8 mm long, 1-4 mm wide, distinctly 3-5-veined, thickish and subgibbous at the base, acute-subacute or somewhat acuminate with puberulous tips; the inner bracts widest, membrane-edged and sometimes almost obtuse. Receptacle convex, alveolate. Ray-florets 8-23, yellow. Tube 1-2 mm long, cylindrical. Lamina narrowly oblong-oblanceolate, sometimes elliptic-oblong-elliptic-obovate, 6-15 mm long, 2.5-5 mm wide, 4-5-veined, soon becoming revolute. Style terete or flattened with swollen base; style branches 0.8-1.5 mm long, obtuse-truncate. Disc-florets c. 30-60. Corolla 3-4 mm long. Tube 1.2-1.8 mm long, cylindrical. Limb campanulate, 1.8-2.5 mm long; lobes deltoid-narrowly triangular, 0.8-1 mm long. Anthers 1.2-1.8 mm long incl. the ovate obtuse appendage. Style subterete or flattened below, becoming terete below the branches; base ± swollen; stylophore distinct, up to 0.25 mm long; style branches 0.3-0.9 mm long, truncate. Pappus bristles numerous, 1-2(-2.5) mm long, white, mostly erect. Achenes (narrowly) oblong-obovate, 3.5-4.5 mm long, 1.5-2.5 mm wide, densely villous-lanate with white(-brownish), erecto-patent hairs, mucilaginous when soaked, with 5 nerves under the indumentum.
More
Shrublet, 0.15-0.9 m tall. Leaves at branch tips and crowded on short-shoots, spathulate-cuneate and apically 3-9-toothed or-lobed, (5-)10-40 mm long, densely grey-velvety. Flowerheads solitary in upper axils on peduncles (20-)50-250 mm long; involucre cup-shaped, (5-)8-15 mm diam., bracts 8-16, connate basally only. Cypselas densely white-woolly, mucilaginous when wet.
