Compositae
The Compositae (or Asteraceae; alternative name) are the largest and most diverse flowering plant family, with about 24 000 species and 1600 - 1700 genera. They occur worldwide, except on Antarctica, in all but the most extreme habitats, reaching their greatest numbers in arid and temperate regions and on tropical and subtropical mountains.
The most recent book on Compositae [Funk et al. (eds) 2009] presents a new view on the phylogeny, biogeography and classification of the family. There are over 300 indigenous species of Asteraceae in New Zealand, with many species being endemic. They belong to some of the most species–rich genera of the flora.
Current research includes phylogenetic studies in Gnaphalieae, Senecioneae, and Astereae (particularly Olearia and Celmisia). This research is undertaken in collaboration with overseas researchers. We are working towards a revision of Craspedia and other genera in Gnaphalieae and Senecioneae. Major studies are undertaken on genetic diversity and systematics of Gnaphalieae. Our research group´s publications include research on the phylogeny of New Zealand Asteraceae, phylogeny of Brachyglottis, Abrotanella, Leptinella, Gnaphalieae, and Craspedia, revision of Anaphalioides, research into the genetic diversity of Gnaphalieae, systematic studies in Haastia, Raoulia, Euchiton, Agyrotegium, Leucogenes, Olearia, Ozothamnus, Rachelia, Helichrysum, Ewartia, and Anaphalioides, and contributions to worldwide studies in Gnaphalieae, Senecioneae, and Asteraeae. We led a GBIF–funded project on a global working checklist of Compositae.
