Phylogenetic tree of the Asteraceae species

Plant phylogeny was constructed by combining the information from a composite tree of the Asteraceae family (Funk et al. 2009) for most genera, with taxonomy serving as a surrogate for phylogenetic relationships of nodes for which no information was available. When even the taxonomy was unable to provide relationships, unresolved nodes were left as polytomies. Species were also attached as polytomies deriving from each genus
