- Morphology General Habit
- Annual perennial or biennial herbs (spiny subshrubs), glabrous, with or without stems, sometimes caespitose, occasionally stoloniferous.
- Morphology Stem
- Stems or flowering stalks 1-several, branching above or simple.
- Morphology Leaves
- Leaves cauline and alternate, or radical and rosulate, entire or sinuate-dentate to runcinate-pinnatipartite, often acicular-denticulate on the margins.
- Morphology Reproductive morphology Inflorescences Capitulum
- Capitula few to numerous, subsessile or shortly stalked, often in lax irregular corymbs, sometimes solitary, or in clusters along the branches.
- Morphology Reproductive morphology Flowers Receptacle
- Receptacle epaleate.
- Morphology Reproductive morphology Inflorescences Bracts Involucre
- Involucres narrowly cylindric-campanulate.
- Morphology Reproductive morphology Inflorescences Bracts Phyllaries
- Phyllaries 2-several-seriate, becoming ± swollen and corky towards the base; the innermost subequal, usually greatly exceeding the outer.
- Morphology Reproductive morphology Flowers Florets
- Florets few to many, yellow, or the ligule sometimes purplish or red outside; anthers sagittate at the base with the auricles shortly setaceous-acuminate; style branches long slender, sweeping hairs long.
- Morphology Reproductive morphology Fruits
- Achenes pale-brown to black, subterete or somewhat angular, or compressed, sometimes apically attenuate or beaked, ribbed; ribs 5-many, uniformly narrow or somewhat inflated, smooth or muricate, glabrous.

- Morphology General Habit
- Annual to perennial herbs, subshrubs or shrublets, sometimes spinescent, with white latex, chiefly glabrous
- Morphology Reproductive morphology Inflorescences
- Flowering stems terminating in synflorescences with few to many capitula Capitula c. 8–45-flowered; involucre slender, phyllaries mostly with distinct scarious margin, in a few outer series and an inner series of distinctly longer, equal, linear-lanceolate ones; receptacle naked
- Morphology Reproductive morphology Flowers Florets
- Florets all ligulate, 5-toothed, bisexual, of some shade of yellow; anthers with sagittate basal and rounded apical appendages
- Morphology Reproductive morphology Fruits
- Achenes homomorphic or heteromorphic, usually slender, c. 2–6 mm long, cylindric to subfusiform, the marginal somewhat curved and flattened; pappus persistent or deciduous, either of ± numerous uniform bristles or of ± numerous outer downy hairs and fewer inner bristles; bristles and hairs scabrid.
- Distribution
- Genus of 55 species mainly in Africa and south-western to southern and central Asia, six in Mediterranean Europe, one each in western Australia and, introduced, in the New World (Caribbean and adjacent regions).
