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.
Generic Delimitation and Phylogeny of the Subtribe Centaureinae (Asteraceae): A Combined Nuclear and Chloroplast DNA Analysis
Abstract Taxonomic complexity has hindered the partitioning of the artificial genus Centaurea, even though it has long been recognized as a polyphyletic assemblage. On the basis of morphology, pollen…
THE CARDUEAE (COMPOSITAE) REVISITED: INSIGHTS FROM ITS, trnL-trnF, AND matK NUCLEAR AND CHLOROPLAST DNA ANALYSIS1, 2
Abstract The new outline of relationships in basal branches of the family Compositae Giseke confirms that the sister group to the tribe Cardueae Cass. are not Mutisieae Cass., but rather a group of…

Both Bayesian and Parsimony analyses indicate that the main morphological characters used in classifications, such as flower shape and capsule dehiscence, have arisen in parallel.

The results show that the sectional classification in current use needs major revision, with many old sections being merged into larger ones and most recent groups in the eastern Mediterranean clade are not resolved and reticulation in the western Mediterranean group of sections makes phylogenetic relationships within these two groups somewhat obscure.
Taxonomic problems in Carthamus (Asteraceae): RAPD markers and sectional classification
The results confirm that methodological problems posed by RAPD markers can be avoided by careful laboratory procedures and appropriate data analyses and suggest that this kind of marker is useful at low taxonomic levels and is, furthermore, complementary to DNA sequence analysis.
Reconstructing the history of Campanulaceae with a Bayesian approach to molecular dating and dispersal-vicariance analyses.

The phylogenetic hypothesis supports the recognition of the following genera and groups and monophyly of Phaenospermateae including Duthieinae is demonstrated, and its inclusion within or treatment as sister to Stipeae is rejected.
The Genus Artemisia and its Allies: Phylogeny of the Subtribe Artemisiinae (Asteraceae, Anthemideae) Based on Nucleotide Sequences of Nuclear Ribosomal DNA Internal Transcribed Spacers (ITS)
The results definitely support the monophyly of the genus Artemisia in its broadest sense and suggest that some infrageneric groups must be redefined, especially the subgenus Artemisia.
Molecular phylogeny and evolution of floral characters of Artemisia and allies (Anthemideae, Asteraceae): evidence from nrDNA ETS and ITS sequences
The Artemisia/Kaschgaria lineage probably originated from an ancestor with disciform capitula, central hermaphrodite florets and Artemisia pollen type, and character reconstruction reveals that discoid capitula and Anthemis pollen type are the ancestral condition in the subtribe.
