KATINAS, Liliana; GUTIERREZ, Diego G.; GROSSI, Mariana A.  e  CRISCI, Jorge V.. An overview of the plant family Asteraceae ( = Compositae) in Argentina. Bol. Soc. Argent. Bot. [online]. 2007, vol.42, n.1-2, pp.113-129. ISSN 1851-2372.

An overview of the family Asteraceae in Argentina that includes a brief taxonomic history, numerical data of tribes, genera and species, examples of endemisms and ecological adaptations, and a discussion on the hypothesis on the origin of the family in Patagonia is given. Asteraceae is the most numerous family in Argentina , with 227 genera (five are endemic) and ca. 1400 species (92 are adventitious and 382 are endemic). In relation to the native taxa, all tribes of Asteraceae occur in Argentina excepting Inuleae (sensu Bremer). Tribes Arctoteae and Calenduleae are represented exclusively by adventitious taxa, and Cardueae has only one native species. Barnadesieae and Mutisieae are the only tribes with endemic genera in Argentina and they also present the highest percentage of genera and species occurring in the country when compared with the rest of the tribes. The highest number of native species occurs in the Altoandean and Patagonian phytogeographic provinces. The most represented tribe in number of genera is Heliantheae, and in number of species is the tribe Senecioneae.
