Abstract:

Maximum parsimony, maximum likelihood and Bayesian phylogenetic analyses of selected Goniothalamus and Richella species (Annonaceae) are presented, based on sequences of three chloroplast markers (matK, psbA-trnH intergenic spacer, and trnL-trnF intergenic spacer). The two genera are shown to be congeneric, and the nomenclatural consequences of this are discussed. Morphological synapomorphies for individual clades are evaluated, although a detailed interpretation of morphological evolution will require more extensive species sampling.
