Sixty-five restriction sites were detected among 11 species of Onagraceae (one each of Circaea, Fuchsia, Hauya, Oenothera, and Ludwigia, and six species of Epilobium) using 20 restriction enzymes. Phylogenetic analysis of the data was performed using both Wagner and Dollo parsimony, and the resulting monophyletic groups were tested by the bootstrap method. The trees were rooted by using Ludwigia as a functional outgroup. Phenetic approaches (cluster analysis and principal coordinate analysis) were also applied to the data as a complement to the cladistic analysis. Wagner parsimony analysis generated four equally parsimonious trees (53 steps, consistency index.0.76), and Dollo parsimony analysis generated six equally parsimonious trees (59 steps, consistency index 0.67). In all trees the six species of Epilobium form a monophyletic group. Independent data on Onagraceae (morphological, cytological, anatomical, chemosystematic, and molecular) strongly support one of the six phylogenetic hypotheses generated by Dollo parsimony analysis, in which Circaea, Fuchsia, and Hauya form one branch with Circaea the sister group to Fuchsia-Hauya, and Oenothera and Epilobium form the other branch. Cluster analysis and principal component analysis do not agree with the phylogenetic analyses mainly in the position of Epilobium, suggesting the possibility of different rates of evolutionary change in different lines of the family.} }
