Phylogenetic analyses of cpDNA restriction sites and chloroplast gene (rbcL, matK), intron (rpoC1, rpl16, rps16), and nuclear rDNA ITS sequences, with supplementary data from chloroplast genome structural rearrangements were used to elucidate major clades within the subfamily. Based on consensus of relationship, 12 major lineages have been inferred of which six have been treated at the tribal level: Bupleureae, Heteromorpheae, Oenantheae, Pleurospermeae, Smyrnieae, and Scandiceae. Heteromorpheae and Bupleureae constitute basal clades, the relationships among the other tribes are not clear. Tribe Scandiceae includes subtribes Scandicinae, Daucinae, and Torilidinae, with the latter two comprising taxa traditionally placed in Caucalideae.
