Morphology General Habit
A perennial herb or subshrub up to c. 1.5 m. tall.
Morphology Stem

Morphology Leaves
Leaves sessile, 3–6 cm. long, dentate to pinnatifid-dentate; lamina (excluding the teeth or lobes) 2–3(4) mm. wide and linear or 5–15 mm. wide and lanceolate; teeth 3–8 on each side, each tooth 2–6(10) mm. long, triangular or linear and extended in a tawny spine 2–3 mm. long; margins of teeth and sinuses entire or armed with smaller spines; upper surface smooth or somewhat scabrous, slightly to densely araneose-tomentose or glabrescent; lower surface whitish felted-tomentose.
Morphology Reproductive morphology Inflorescences Capitulum
Capitula radiate, solitary and terminal on the branches, or subcorymbosely arranged, 2.5–5(+?) cm. in diam. including the rays.
Morphology Reproductive morphology Inflorescences Bracts Phyllaries
