includes over 32,000 currently accepted species, in over 1,900 genera (list) in 13 subfamilies. In terms of numbers of species, the Asteraceae are rivaled only by the Orchidaceae. Which of the two families actually is the larger is unclear, because of the uncertainty about how many extant species each family includes.
Nearly all Asteraceae bear their flowers in dense heads (capitula or pseudanthia) surrounded by involucral bracts. When viewed from a distance, each capitulum may have the appearance of being a single flower. Enlarged outer (peripheral) flowers in the capitula may resemble petals, and the involucral bracts may look like a calyx. The name Asteraceae comes from the type genus Aster, from the Ancient Greek ἀστήρ, meaning star, and refers to the star-like form of the inflorescence. Compositae is an older (but still valid) name that refers to the "composite" nature of the capitula, which consist of (few to) many individual flowers." - (en.wikipedia.org 18.04.2020)
