Asteraceae
Phylogeny

The phylogenetic tree of subfamilies presented below is based on Panero & Funk (2002) updated in 2014, and now also includes the monotypic Famatinanthoideae. The diamond (♦) denotes a very poorly supported node (<50% bootstrap support), the dot () a poorly supported node (<80%).

The family includes over 32,000 currently accepted species, in over 1,900 genera (list) in 13 subfamilies. The number of species in the family Asteraceae is rivaled only by Orchidaceae. Which is the larger family is unclear, because of the uncertainty about how many extant species each family includes. The four subfamilies Asteroideae, Cichorioideae, Carduoideae and Mutisioideae contain 99% of the species diversity of the whole family (approximately 70%, 14%, 11% and 3% respectively).

Because of the morphological complexity exhibited by this family, agreeing on generic circumscriptions has often been difficult for taxonomists. As a result, several of these genera have required multiple revisions.
