Description: Root perpendicular, simple; stems many from the crown, diffuse or decumbent, tomentose; leaves tapering at base into a petiole, oblongo-lanceolate, on both sides tomentose, undulate, minutely calloso-serrulate; heads subsessile, discoid, terminal or lateral; outer invol. sc. cobwebbed or glabrous, very much acuminate, squarrose, nerved, inner lanceolate, acute, nerveless, erect; disc-achenes furrowed, marginal sterile; pappus of the marg. fl. bristle-shaped, serrate, of the disc double, the outer bristle-shaped, inner plumose beyond the middle, expanded at base. Probably an annual or biennial. Stems 6–12 inches long or more, laxly leafy. Leaves 1–1.5 inch long, 2–4 lines wide, like those of some Aizoon. Invol. in the majority of specimens seen by me quite glabrous, as in DC.'s var. leiolepis Inv. scales white or straw-colour. (from JSTOR Global Plants website / Flora Capensis)

Prostrate or low spreading perennial herb from a woody taproot. Stems annual, many from the root crown, sometimes woody at the base, decumbent to c. 30 cm long, branched, leafy, appressed greyish-lanate. Leaves subsessile or with the midrib petiole-like in the lower c. 10 mm, mostly 10–40 x 3–10 mm, narrowly elliptic to narrowly oblanceolate, obtuse mucronate at the apex, narrowly cuneate or attenuate below; margins finely undulate, minutely callose-serrulate; midrib sometimes recurved and the lamina conduplicate; upper surface thinly greyish araneose, paler lanate beneath. Capitula few to many, solitary and terminal on branches or short shoots, subsessile axillary, subtended by several leaves. Involucres mostly 12–20 x 6–10 mm, spreading to c. 25 mm across the squarrose phyllaries, campanulate. Phyllaries numerous, stiffly chartaceous, usually squarrose in upper half, finely araneose-lanate where exposed, or glabrescent, finely serrulate-ciliate; the outer phyllaries from c. 34 mm long, finely subulate, the inner to c. 20 mm long and linear-lanceolate tapering to an acute or acuminate pungent apex. Outer florets neuter; corollas rudimentary, 4–5 mm long, filiform; ovary rudimentary, finely setulose from the base; pappus several-seriate of numerous barbellate setae to (7)9–11 mm long, shorter than the involucre. Inner floret corollas pale-mauve, to c. 7 mm long, lobes linear erect but recurved at the apex; achenes to c. 3 mm long, narrowly turbinate, strongly 10-ribbed, uniformly densely appressed-ascending setose-strigose between the ribs, the basal hairs shorter more numerous and spreading; pappus 2-seriate, the outer series of 15–20 slender subplumose-ciliolate setae c. 8 mm long, the inner of c. 5 narrowly scale-like setae c. 8 mm long, broadly white scarious-winged in the lower half, subplumose-ciliolate above.
