The early evolution of the flowering plant order Apiales is discussed based on information from morphology and DNA sequences from four genes ( ndhF , rbcL , atpB and matK ). A model‐based approach of analysis, Bayesian inference, is used to analyse the data and the results are compared with those from parsimony analysis. In particular, a new family of the order, the monogeneric Pennantiaceae from New Zealand and Australia, aids in the understanding of how the order originated. The ancestor of Apiales was probably a shrub or small tree with alternate, simple leaves, paniculate inflorescences, five‐merous flowers with free petals, and drupes. © 2003 The Linnean Society of London, Botanical Journal of the Linnean Society , 2003, 141 , 1–24.
