452.0000 Family Asteraceae Dumort.; Commentat. Bot. [Dumortier] 55 (1822)
1620 genera, ca. 29.000 spp. (35.000 spp. incl. microspecies). Systematics taken mostly from Funk et al. (2009, 2020) and Zuntini et al. (2024). Barnadesioideae (so far treated as most basal member of Asteraceae) might be a separate family, more related to Calyceraceae.
