Morphology Leaves

Leaves pale green, narrowly obovate to narrowly spatulate, 1.5–10 cm long, 0.2–3 cm wide, the base long-attenuate (in more proximal leaves) to cuneate (in more distal leaves), the margin serrate-dentate to almost lobed, to almost entire in more distal leaves, the apex obtuse and mucronate, or pinnatipartite with 2–3 pairs of lobes, tapering to the base, the lobes divided almost to the midrib, narrowly oblong to linear, the margins entire, dentate or lobed, mucronate, pubescent on both sides or rarely glabrous, densely glandular.

Morphology Reproductive morphology Inflorescences Capitulum

Capitula 2–5 mm long, united in laxly corymbose or subglobose cymes, which in turn form a terminal lax leafy panicle or corymb; stalks of individual capitula 2–5 mm long, glabrous to pubescent; phyllaries oblong or lanceolate, 1–3 mm long, 0.4–0.6 mm wide, the margins fimbriate or serrate, hyaline towards the apex, acute or obtuse, (sparsely) pubescent, glandular; receptacle toroid, with spinules.

Morphology Reproductive morphology Flowers Florets

Ray florets yellow, 40–58, tube cylindrical, 1.2–1.4 mm long, ray 0.4–0.5 mm long and about as wide, 2–3-dentate or -lobed, style ± 1.5 mm long; disc florets yellow, 9–20, cylindrical proximally, campanulate distally, tube 1.3–1.5 mm long, lobes 0.4–0.6 mm long, pilose, occasionally glandular distally; anthers 0.7–0.9 mm long with triangular appendages; style 1.6–1.7 mm long with triangular appendages to the arms.

Morphology Reproductive morphology Fruits

Achenes ellipsoid, 0.7–1.1 mm long, pubescent to sparsely pilose; pappus of 11–15 barbellate setae 1.5–2 mm long.
