Everywhere but Antarctica: using a supertree to understand the diversity and distribution of the Compositae.
The results of molecular phylogenetic studies of members of tribes Helenieae, Heliantheae, and Eupatorieae (Asteraceae) and General systematics and proposed taxonomic changes in current classification are presented.
A phylogeny of the "evil tribe" (Vernonieae: Compositae) reveals Old/New World long distance dispersal: support from separate and combined congruent datasets (trnL-F, ndhF, ITS).
A combined approach using DNA sequence data from two chloroplast regions, the ndhF gene and the noncoding spacer trnL-F, and from the nuclear rDNA ITS region for 90 taxa from throughout the world was used to reconstruct the evolutionary history of the Vernonieae.
A phylogeny of the Gochnatieae: Understanding a critically placed tribe in the Compositae
Insights into the evolution of the tribe Arctoteae (Compositae: subfamily Cichorioideae s.s.) using trnL-F, ndhF, and ITS
The analyses showed robust support for two outgroup clades, Liabeae-Vernonieae and Gundelieae-Lactuceae and two main subtribes within Arctoteae and Gorteriinae, which shows that the unusual taxa are of critical importance, and they should be included in any molecular analysis.
Goldfields Revisited: A Molecular Phylogenetic Perspective on the Evolution of Lasthenia (Compositae: Heliantheae sensu lato)
Overall patterns of divergence in the molecular trees for Lasthenia conform to expectations of saltational diversification, with an initial rapid radiation followed by long periods of minimal diversification in each group preceding relatively recent episodes of speciation.
Molecular and morphological reassessment of relationships within the Vittadinia group of Astereae (Asteraceae).

The distribution of indels and the combined analysis each provide evidence that the Hawaiian and Cook Island species of Tetramolopium are descended from New Guinea species and suggest that the Cook Islands species T. mitiaroense is sister to the Hawaiian clade.

An edaphically linked ecological role for flavonoid differences that first revealed the existence of two races is hypothesized, suggesting that one or both edaphic races evolved in parallel in the two clades.
Phylogeny of the Spiny African Daisies (Compositae, tribe Arctotideae, subtribe Gorteriinae) based on trnL-F, ndhF, and ITS sequence data.
Support for the major clades and most of the sub-groups is strong but the relationships among some of the terminal taxa are variable.
Cryptic goldfields: a molecular phylogenetic reinvestigation of Lasthenia californica sensu lato and close relatives (Compositae: Heliantheae sensu lato).
Maximum parsimony analysis of DNA sequence data from the internal and external transcribed spacer regions of 18S-26S nuclear ribosomal DNA and the 3' trnK intron of chloroplast DNA yielded a well-supported tree showing that the most common species of Lasthenia, L. californica sensu lato (s.l.), is not monophyletic.
Cymbonotus (Compositae: Arctotideae, Arctotidinae): an endemic Australian genus embedded in a southern African clade
Molecular data from internal transcribed spacer (ITS), ndhF, and trnL-F sequences were used to determine the patterns of relationships within the subtribe Arctotidinae, which is restricted to southern Africa except for the Australian genus Cymbonotus.
