Morphology Reproductive morphology Inflorescences Bracts Involucre
Involucres 3–8 x 4–10 mm., campanulate.
Morphology Reproductive morphology Inflorescences Bracts Phyllaries
Phyllaries numerous, scarious with subhyaline margins, sparsely hispid to glabrescent, finely ciliate-pectinate on the margins towards the apex, often purple-tinged in the upper half, the outer from c. 1.5 mm. long, the inner to c. 8 mm. long, ovate to narrowly lanceolate, ± tapering acuminate to a short pungent or bristle tip.
Morphology Reproductive morphology Flowers Corolla
Corollas mauve or purplish, rarely whitish, mostly 4–10 mm. long, tubular, widening gradually upwards, usually glabrous except for scattered glands.
