The family Asteraceae, with the original name 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 Ancient Greek words ἥλιος and χρῡσός.
Senecioneae is the largest tribe of the Asteraceae, or the sunflower family, comprising over 150 genera and over 3,500 species. Almost one-third of the species in this tribe are placed in the genus Senecio. Its members exhibit probably the widest possible range of form to be found in the entire plant kingdom, and include annuals, minute creeping alpines, herbaceous and evergreen perennials, shrubs, climbers, succulents, trees, and semi-aquatic plants.
Argyroxiphium is a small genus of plants in the family Asteraceae. Its members are known by the common names silversword or greensword due to their long, narrow leaves and the silvery hairs on some species. The silverswords belong to a larger radiation of over 50 species, including the physically different genera Dubautia and Wilkesia. This grouping is often referred to as the silversword alliance. Botanist P. H. Raven referred to this radiation as "the best example of adaptive radiation in plants".
Harold Ernest Robinson was an American botanist and entomologist.
Viscount Alexandre Henri Gabriel (vicomte) de Cassini was a French botanist and naturalist, who specialised in the sunflower family (Asteraceae).
The Heliantheae are the third-largest tribe in the sunflower family (Asteraceae). With some 190 genera and nearly 2500 recognized species, only the tribes Senecioneae and Astereae are larger. The name is derived from the genus Helianthus, which is Greek for sun flower. Most genera and species are found in North America and South America. A few genera are pantropical.
The Gnaphalieae are a tribe of flowering plants in the family Asteraceae. It is most closely related to the tribes Anthemideae, Astereae, and Calenduleae.
Eriophyllum, commonly known as the woolly sunflower, is a North American genus of plants in the family Asteraceae. The genus is native to western North America, with a concentration of narrow endemics in California.
Microseris is a genus of plants in the tribe Cichorieae within the family Asteraceae, plants that often called composites. They are native to North America, South America, Australia, and New Zealand.
Tageteae is a tribe of the plant family Asteraceae. It consists of approximately 260 species divided among 32 genera. All are found in the New World, with a center of diversity in the Mexican highlands. The type genus is Tagetes (marigolds).
Rhaponticum is a genus of flowering plants in the tribe Cardueae within the family Asteraceae. As of November 2023, it is accepted by Plants of the World Online, but rejected by the Global Compositae Database in favour of Leuzea.
Lessingia is a genus of plants in the family Asteraceae which are native to western North America. Several species are endemic to California.
The Cichorioideae are a subfamily of the family Asteraceae of flowering plants. Familiar members of Cichorioideae include lettuce, dandelions, chicory and Gazania species. The subfamily comprises about 240 genera and about 2900 species. It is heterogeneous and hard to characterize except with molecular characters.
Polyanthina is a genus of flowering plants in the tribe Eupatorieae within the family Asteraceae.
Hyaloseris is a genus of South American flowering plants in the family Asteraceae.
Melanthera, is a genus of perennial flowering plants in the family Asteraceae, native to North and South America, as well as Africa, Asia and Oceania, including Hawaiʻi.
Pseudoblepharispermum is a genus of flowering plants in the daisy family, native to East Africa.
Chrysactinium is a genus of South American flowering plants in the family Asteraceae.
Helenieae is a tribe of the plant family Asteraceae. The type genus is Helenium, but the best known members of the tribe are the Gaillardia. Helenieae are usually placed in their own tribe, but some authors include this and several other tribes as subtribes within a broader definition of the tribe Heliantheae.
