Abstract

Dorema, Ferula and Leutea are member-genera of Apiaceae tribe Scandiceae subtribe Ferulinae. Their placement in Scandiceae was established based only on nuclear ribosomal DNA internal transcribed spacer (nrDNA ITS) sequence variation. Previous molecular studies suggested that Dorema and Leutea are nested within Ferula. To confirm issues of relationships and eventual nomenclatural changes, we increased taxonomic sampling and examined nrDNA ITS and three rapidly evolving cpDNA markers: rpoB-trnC intergenic spacer and rps16 and rpoC1 introns. Ninety-one species were included representing 68 species of Ferula, six species of Dorema, nine species of Leutea and eight outgroup taxa. Nuclear and plastid DNA data were analysed separately and combined using maximum likelihood and Bayesian approaches; based on the resulting trees several topological hypotheses on relationships among these genera were tested. Data incongruence was assessed using internode certainty (IC) and tree certainty (TC) measures. In all analyses, Leutea was monophyletic. In nrDNA trees it was nested within Ferula, while in cpDNA and combined data trees it was sister to Ferula + Dorema clade. In all analyses, species of Dorema were placed in one subclade of Ferula and intermingled with its members. Despite the incongruence of nrDNA and cpDNA data, the IC support for the sister position of Leutea to remaining Ferulinae and the TC support was higher in combined analyses than in the analyses of cpDNA data alone. Our results support the taxonomic position of Leutea as a separate genus but suggest that Dorema is subsumed within Ferula.
