Cottony annual herbs. Stem reduced, unbranched, or branched, branches prostrate and terminating in an inflorescence. Leaves alternate or sometimes opposite, sessile, tomentose. Capitula discoid, homogamous, single or 2–12 aggregated to form a compound head and the whole surrounded by a general involucre of leaf-like bracts; bracts multiseriate, usually hyaline but with a green midrib, each bract with a yellow, opaque lamina which is most prominent and reflexed in the middle and inner bracts, most bracts with copious, long, marginal hairs. Florets bisexual; corolla tubular, (4–)5-lobed, yellow; style branches truncate; stamens 5, anthers tailed. Cypselas covered in mucilage-producing cells, style-base persisting in mature fruit; pappus of (4–)5(–6) plumose bristles united at base, strongly reflexed when released from capitulum.
An endemic Australian genus containing 4 species, 3 restricted to Western Australia.
