Abstract
The evolutionary relationships among the seven tribes of Onagraceae, the most intensively studied family of intermediate size, have been examined from morphological and molecular perspectives. Previous cladistic analyses of chloroplast (cp) and nuclear ribosomal (nr) DNA restriction sites, nuclear-encoded rbcS amino acid sequences, nrRNA nucleotide sequences, and morphological characters, produced trees that agree in defining the tribe Jussiaeeae as the sister group to the rest of the family. However, the relationships among the rest of the tribes are not completely resolved by these analyses. Cladistic analyses of sequence data from the chloroplast encoded rbcL gene produced results that bear on two major issues: (i) intertribal relationships within Onagraceae, and (ii) congruence with other cladistic analyses. Sequences of rbcL were obtained from all tribes of Onagraceae and from three families that have been proposed as sister taxa of Onagraceae on the basis of other molecular and morphological evidence (Lythraceae, Punicaceae, Trapaceae). Phylogenetic analysis of rbcL sequence data produced a single most parsimonious tree, both Fitch and weighted, that defines three strongly supported monophyletic groups within the family: all tribes except Jussiaeeae; Onagreae and Epilobieae; and, most interestingly, Fuchsieae and Circaeeae. The formation of this last clade corroborates the results of the cpDNA restriction site and of the nrRNA sequence data. The data also indicate an apparent slowdown in the rate of rbcL sequence divergence in the woody Fuchsia lineage relative to the herbaceous Circaea lineage. The placements of monogeneric tribes Lopezieae and Hauyeae are not strongly supported. The topology of the rbcL tree basically confirms that of the cpDNA restriction site tree. Among the other cladistic analyses, the nrRNA sequence survey produced the tree closest to the rbcL tree, followed in order by the rbcS amino acid sequence tree, the nrDNA restriction site tree, and the morphological tree
