Annual or perennial herbs or shrubs, usually with some glandular hairs. Leaves cauline, petiolate or sessile, alternate, lower ones sometimes opposite, entire. Capitula broad-campanulate or hemispherical, terminal, in diffuse groups of up to 8, or solitary, subsessile or pedunculate; involucral bracts in several series, unequal, papery, with or without a herbaceous basal claw, mostly yellow or white; intermediate involucral bracts longest; receptacle flat, naked, pitted. Florets all bisexual or some or all outer florets female, yellow; corolla 5-lobed (females 2–4-lobed); anthers tailed at base; style with truncate, acute or swollen branches. Cypselas obloid, glabrous, pitted; pappus of barbellate bristles, free or united in a ring at base.

An endemic Australian genus of 17 species.

Coronidium was erected as part of an ongoing effort to accommodate Australian species that were once misplaced in Helichrysum (Wilson 2008). Helichrysum s.s. may contain only a single species in Australia (see notes under Helichrysum). Recent studies using analyses of DNA data have shown Coronidium to be composed of several separate lineages, including one that is most closely related to Xerochrysum and another that is most closely related to Chrysocephalum. Consequently, species currently included under Coronidium will be subjected to further taxonomic revision in the future (Schmidt-Lebuhn et al. 2015). Schmidt-Lebuhn et al. (2015) also showed Helichrysum leucopsideum to be closely related to Coronidium adenophorum. However, this species is currently retained within Helichrysum (see notes under Helichrysum).

The C. scorpioides complex was revised by Walsh (2014).
