The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales. Commonly referred to as the aster, daisy, composite, or sunflower family, Compositae were first described in the year 1740. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown.
The genus Helichrysum consists of an estimated 600 species of flowering plants in the sunflower family (Asteraceae). The type species is Helichrysum orientale. They often go by the names everlasting, immortelle, and strawflower. The name is derived from the Greek words ἑλίσσω and χρῡσός.
Pallenis is a small genus of flowering plants in the tribe Inuleae within the family Asteraceae. The name is derived from palea (chaff), referring to the chaffy receptacle.

Gamochaeta is a genus of flowering plants in the family Asteraceae. There has not always been agreement among botanists regarding its status as a recognized genus, but it has become more accepted in recent years. It currently includes many plants that previously belonged in genus Gnaphalium. Like many species of Gnaphalium, many Gamochaeta are called cudweeds or everlastings.
Argyrotegium is a genus of plants in the family Asteraceae, native to Australia and New Zealand.
Panaetia, a genus in the Asteraceae (daisy) family, was first described by Henri Cassini in 1829 It is considered by Plants of the World online and the Global Compositae Database to be a synonym of Podolepis Labil,. while GBIF states it as "doubtful". However, in 2021, the Western Australian Herbarium accepted Jeffery Jeanes new circumscription of the genus, together with two species of Panaetia as being found in Western Australia: Panaetia lessonii, and Panaetia tepperi. Jeanes distinguished Panaetia from the genera, Podolepis, Siemssenia and Walshia, using the following characters:
- the outer florets are all tubular; and
- the cypselas are minutely tuberculate and lack long finger-like papillae.
