Belongs within: Asteraceae.
Contains: Senecio, Gnaphalieae, Astereae, Anthemideae, Calenduleae, Inuleae, Plucheeae, Heliantheae.
The Asteroideae is a major clade within the composite-flowered plants, a major characteristic of which is the presence of true ray florets in many species.
Synapomorphies (from www.mobot.org): Sesquiterpene lactones at biogenetic levels 3 and 4, benzopyrans, benzofurans present; ray florets common, female, disc florets with corolla shallowly lobed, perfect; anthers often ecalcarate and usually ecaudate; pollen 25.0-34.3 µm in diameter, colpus ends acute, exine 2.3-4.2 µm across, with a double tectum; style hairs often rounded, only more or less at style tip, stigmatic areas in two marginal bands; n = (4-)9-10(-19); rbcL 6bp x 4 inversion.
