Abstract
A phylogenetic study of Asteridae sensu lato was conducted based on chloroplast ndhF gene sequences for 116 ingroup and 13 outgroup species. Prior molecular studies based on rbcL sequences identified terminal groups corresponding to families, but were unable to resolve relationships among them. These results are largely consistent with earlier rbcL studies, but provide much greater resolution and stronger bootstrap support throughout the tree. The parsimony analysis found eight equally parsimonious trees, all of which recognize four major clades with the following relationship: (Cornales (Ericales (Euasterids I, Euasterids II))). Euasterids I includes (Garryales ((Solanales, Boraginaceae) (Gentianales, Lamiales))), although with weak support for relationships among the named clades. Euasterids II includes (Aquifoliales (Asterales (Apiales, Dipsacales))) with strong support for these relationships. Relationships within Ericales are weakly supported and merit further attention.
