{{short description|List of flowering plants in the family Asteraceae recorded from South Africa}}
'''[[Biology:Asteraceae|Asteraceae]]''' or '''Compositae''' is a family of [[Biology:Flowering plant|flowering plant]]s (anthophytes) in the [[Biology:Order|order]] [[Biology:Asterales|Asterales]]. '''Asteraceae''' (commonly referred to as the '''aster''', '''daisy''', '''composite''',<ref name=GBW /> or '''sunflower family'''), is a very large and widespread family,<ref name="Stevens 2001" /><ref name="Jeffrey 2007" /> which includes over 32,000 currently accepted species, in over 1,900 genera ([[Biology:List of Asteraceae genera|list]]) in 13 subfamilies.<ref name="PlantList" /> In terms of numbers of species, the Asteraceae are rivaled only by the [[Biology:Orchidaceae|Orchidaceae]].<ref name="Stevens 2001" /><ref name="Panero & Crozier" /> Nearly all Asteraceae bear their flowers in dense heads (capitula or pseudanthia) surrounded by [[Biology:Bract#Involucral bracts|involucral bracts]]. When viewed from a distance, each capitulum may appear to be 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 ''[[Biology:Aster (genus)|Aster]]'', from the [[Social:Ancient Greek|Ancient Greek]] {{wikt-lang|grc|ἀστήρ}}, meaning star, and refers to the star-like form of the inflorescence. The alternative name Compositae is still valid under the International Code of Nomenclature for algae, fungi, and plants.<ref name="ICN185" /> It refers to the "composite" nature of the capitula, which consist of a few or many individual flowers.

Most members of Asteraceae are [[Biology:Annual plant|annual]] or [[Biology:Perennial|perennial]] herbs, but a significant number are also shrubs, vines, or trees. The family has a [[Biology:Cosmopolitan distribution|cosmopolitan distribution]], with species ranging from subpolar to tropical regions, colonizing a wide variety of habitats. The largest proportion of the species occur in the [[Earth:Arid|arid]] and semiarid regions of subtropical and lower temperate latitudes.<ref name="Barkley et al." />

23,420 species of vascular plant have been recorded in South Africa, making it the sixth most species-rich country in the world and the most species-rich country on the African continent. Of these, 153 species are considered to be threatened.<ref name="Butler 2019" /> Nine [[Biology:Biome|biome]]s have been described in South Africa: [[Biology:Fynbos|Fynbos]], Succulent Karoo, [[Earth:Desert|desert]], Nama Karoo, [[Earth:Grassland|grassland]], [[Earth:Savanna|savanna]], Albany thickets, the Indian Ocean coastal belt, and [[Earth:Forest|forest]]s.<ref name="PlantZAfrica" />

The 2018 [[Organization:South African National Biodiversity Institute|South African National Biodiversity Institute]]'s National Biodiversity Assessment plant checklist lists 35,130 taxa in the phyla [[Biology:Anthocerotophyta|Anthocerotophyta]] (hornworts (6)), [[Biology:Anthophyta|Anthophyta]] (flowering plants (33534)), Bryophyta (mosses (685)), [[Biology:Cycadophyta|Cycadophyta]] (cycads (42)), [[Biology:Lycopodiophyta|Lycopodiophyta]] (Lycophytes(45)), [[Biology:Marchantiophyta|Marchantiophyta]] (liverworts (376)), [[Biology:Pinophyta|Pinophyta]] (conifers (33)), and [[Biology:Pteridophyta|Pteridophyta]] (cryptogams (408)).<ref name="Plants 2018" />

329 [[Biology:Genus|genera]] are represented in the literature. Listed [[Biology:Taxon|taxa]] include [[Biology:Species|species]], [[Biology:Subspecies|subspecies]], [[Biology:Variety (botany)|varieties]], and [[Biology:Form (botany)|forms]] as recorded, some of which have subsequently been allocated to other taxa as [[Biology:Synonym (taxonomy)|synonyms]], in which cases the accepted taxon is appended to the listing.<ref name="Plants 2018" /> Multiple entries under alternative names reflect taxonomic revision over time.
