Abstract

ITS sequences of members of Peucedanum and its segregates (Cervaria, Holandrea, Imperatoria, Oreoselinum, Pteroselinum, Thysselinum, Tommasinia, and Xanthoselinum), as well as representatives of other members of the previously identified 'Angelica' and 'Arracacia' clades, were analysed using distance, maximum likelihood, and maximum parsimony methods in order to establish their phylogenetic relationships. The 'Angelica' and 'Arracacia' clades comprise a strongly supported monophyletic group that is formally recognised as tribe Selineae. The genus Holandrea, expanded to include Cervaria caucasica and Peucedanum achaicum, is distantly related to the other peucedanoid genera. The remaining segregates are closely related to one another and to Peucedanum sensu stricto. The genera Seseli and Selinum are polyphyletic. Members of the genus Angelica form a single clade that also includes representatives of Selinum and Sphenosciadium. New combinations in Holandrea (H. caucasica, H. achaica) and Angelica (A. capitellata) are proposed, and Selinum pyrenaeum is recognised in Angelica (A. pyrenaea).
