Presents a study which used nuclear 25S rDNA sequences to corroborate and test previously published matK-rbcL-based hypotheses of phylogenetic relationships in Cornales. Taxa sequences generated; Relationships among the major lineages; Discrepancies in relationships; Incongruence between the 26S rDNA-matK-rbcL data sets; Taxonomic conscription of Cornales and phylogenetic relationships within Cornales.
