Morphology General Habit
Perennial herbs with annual stems from small woody rootstocks; rootcrowns with or without lanate tufts; roots numerous, thong-like and usually swelling to form root-tubers.
Morphology General Indumentum
Vegetative indumentum a varying mixture of large long-stalked flagelliform hairs intermixed with short-stalked T-shaped hairs, the elongate terminal cell of the T-shaped hairs transverse and ± equal-armed, or ± excentric-ascending.
Morphology Stem
Stems erect usually branching above, leafy, sometimes scapiform.
Morphology Leaves
Leaves alternate, sessile or subsessile, bases cuneate less often auriculate; upper surface ± scabrous, sparsely pubescent or glabrescent, the hairs scattered flagelliform often becoming somewhat rigid; lower surface pubescent or felted, sometimes finely pilose especially on the nerves, or glabrescent, glandular-punctate.
Morphology Reproductive morphology Inflorescences Capitulum
Capitula homogamous, solitary or few-many in lax corymbiform cymes, or aggregated in ± dense 3-many-capitulate terminal clusters, or clusters lateral and ± scorpioidly cymose.
Morphology Reproductive morphology Inflorescences Bracts Involucre
Involucres campanulate to broadly cup-shaped, occasionally subglobose or narrowly ovoid.
Morphology Reproductive morphology Inflorescences Bracts Phyllaries
Phyllaries imbricate, several-seriate.
Morphology Reproductive morphology Flowers Receptacle
Receptacle ± flat.
Morphology Reproductive morphology Flowers Corolla
Corollas purple, narrowly funnel-shaped, regularly deeply 5-lobed; lobes apically setulose or glabrous.
Morphology Reproductive morphology Flowers Androecium Stamens Anthers
Anthers with a narrowly triangular hyaline appendage at the apex and short subobtuse tails at the base.
Morphology Reproductive morphology Flowers Gynoecium Style
Style-arms subulate, hairy outside.
Morphology Reproductive morphology Fruits
Achenes narrowly oblong-obovoid, 4–5-angular with narrow ribs on the angles, truncate to slightly rounded at the apex, faces between the ribs with large scattered brownish glandular cells, very sparsely hispid or glabrous.
Morphology Reproductive morphology Seeds
Pappus 2-seriate, the outer of short lacerate free or ± united scales or reduced to a low rim, the inner of short very caducous barbellate setae.
Morphology Reproductive morphology Flowers Pollen
Pollen described as tricolporate, subechinolophate to echinate and micropunctate.
