Epaltes australis, photographed by Ian Sutton.

Belongs within: Asteroideae.

The Plucheeae is a group of composite-flowered plants distinguished by their flowers with filiform style-branches. A number of species of the pantropical to warm temperate genus Pluchea are known as camphorweeds or sourbushes owing to their strong odour.

Characters (from Black & Robertson 1965, as Plucheinae): Style-branches filiform, stigmatic on inner side, beset with collecting hairs downwards to below place of division; heads heterogamous-discoid, female flowers usually with minute ligules or none; bisexual flowers often sterile with shortly bifid or entire styles; receptacle naked.
