Coronidium is a genus of about 21 species of flowering plants in the family Asteraceae. Plants in the genus Coronidium are perennial herbs with disc-like heads of flowers, surrounded by several rows of involucral bracts, the florets usually bisexual with narrowly cylindrical petals forming a tube. After flowering, glabous, oblong cypselas form with a bristly pappus.[2][3][4]

Taxonomy

The genus Coronidium was first formally described in 2008 by Paul G.Wilson in the journal Nuytsia. The type species is Coronidium oxylepis, previously known as Helichrysum oxylepis, formally described in 1858 by Ferdinand von Mueller in his Fragmenta Phytographiae Australiae from specimens collected on Moreton Island.[2][5] The species name is derived from the Greek words korone meaning 'a crown' and the diminutive -idion, referring to the short pappus crown in the Coronidium oxylepis group of species.[2]

Distribution

The genus Coronidium is endemic to eastern Australia, apart from two species that also occur in South Australia and one that extends into Tasmania.[2]
