Description: Small annual herbs, low-growing, with short glandular and/or dense non-glandular hairs.
Leaves mostly cauline and upper alternate, entire.
Heads terminal, solitary, sessile to pedunculate; involucral bracts 1- or 2-seriate, herbaceous with scarious margins; receptacle flat, pitted, scales absent. Florets all tubular, bisexual, fertile, 3–5-toothed, outer strongly decurved and overhanging involucre. Corollas narrow-cylindric to funnel-shaped, glandular or tomentose. Anthers shortly ciliate-tailed, terminal appendages acute. Style branches linear, flattened, conical or subulate papillose apices.
Achenes narrow-cylindrical, beak straight or curved, striate, papillate; pappus of short bristles or scales or absent.
Distribution and occurrence: World: c. 10 species, endemic Australia. Australia: all states except N.T. [includes Toxanthes]
