Morphology General Habit

Annual or short-lived perennial herb, 30–60 cm high, simple or branched; stems decumbent first, then erect, covered in long white or silvery hairs

Morphology Leaves

Leaves with the lower surface paler, sessile, oblanceolate to narrowly obovate, 1–10´0.3–1.8 cm, base narrowing and sometimes slightly auriculate, margins entire, apex obtuse or acute, lanate on both surfaces

Morphology Reproductive morphology Inflorescences

Capitula straw-coloured to golden, many together in dense glomerules 1–2 cm across, glomerules solitary and terminal or several together; stalks of individual capitula up to 2 mm long; phyllaries pale golden-brown or straw-coloured, lanceolate, 3–4 mm long

Morphology Reproductive morphology Flowers Florets

Outer florets white or yellow,±100, filiform, 1.6–2.2 mm long, lobes ± 0.1 mm long and reddish; inner florets 5–15(–30), cylindric, 1.3–2 mm long, lobes 0.1–0.3 mm long

Morphology Reproductive morphology Fruits

Achenes 0.5–0.6 mm long; pappus of barbellate bristles 1.5–2.3 mm long, coherent at base by cilia, caducous with the corolla.

Distribution

N2; widespread as a (sub)tropical weed.

Ecology

Altitude range 1350 m.

Morphology General Habit

Annual or short-lived perennial herb, 30–60 cm high, simple or branched; stems decumbent first, then erect, covered in long white or silvery hairs.

Morphology Leaves

Leaves discolorous with the abaxial surface paler, sessile, oblanceolate to narrowly obovate, the most distal leaves much smaller and linear, 1–10 cm long, 0.3–1.8 cm wide, base narrowing and sometimes slightly auriculate, margins entire, apex obtuse or acute, lanate on both surfaces.

Morphology Reproductive morphology Inflorescences Capitulum

Capitula straw-coloured to golden, 2.5–5 mm long, many together in dense glomerules 1–2 cm across, glomerules solitary and terminal or several together in terminal corymbs; stalks of individual capitula sessile or up to 2 mm long, lanate; receptacle shortly honeycombed; phyllaries in 3 series, chaffy, pale golden-brown or straw-coloured, lanceolate, 3–4 mm long, acute, the stereome divided around a green hairy centre and 1–2 mm long.

Morphology Reproductive morphology Flowers Florets

Outer florets white or yellow, ± 100, tube filiform, 1.6–2.2 mm long, lobes≤0.1 mm long and reddish; style 1.8–2.4 mm long with short obtuse reddish arms; inner florets 5–15(–30), tube cylindric, 1.3–2 mm long, lobes 0.1–0.3 mm long, glabrous and slightly glandular; anthers 0.5–0.8 mm long, briefly caudate, with a triangular distal appendage.

Morphology Reproductive morphology Fruits

Achenes ellipsoid, 0.5–0.6 mm long, papillose; pappus of barbellate bristles 1.5–2.3 mm long, coherent at base by cilia, caducous with the corolla.
