Description: Annual & perennial herbs, woolly with fine septate hairs and often with minute glandular hairs, or glabrescent.
Leaves in a basal rosette and cauline, alternate, entire.
Inflorescence of terminal heads, solitary or in contracted to elongated cymes, usually discoid to radiate; heads campanulate to hemispherical, usually with scale leaves at the peduncle apex merging with involucral bracts; outer bracts sessile, scarious; intermediate bracts, when differentiated, with scarious laminas on successively longer rigid linear claws. Outer florets yellow, rarely white, in 1 row, female, fertile, tubular to ligulate, rarely absent. Disc florets yellow, rarely white, bisexual, fertile, tubular, 5-toothed. Style branches truncate.
Achenes terete, papillose; pappus of numerous bristles, barbellate to shortly plumose, free or fused at the base only, rarely absent from outer florets.
Distribution and occurrence: World: 20 species, endemic Australia. Australia: all States.
