Sažetak
Thirty-two taxa representing 12 sections of the genus Hypericum were analyzed along with two representatives of Thornea using nuclear ITS sequences in order to assess the scope of phylogenetic relationships in this species-rich genus. The resulting parsimony analysis corroborates the actual classification and interspecific affinities. The molecular data provide support for the monophyletic assemblage of the sections Androsaemum, Olympia and Drosocarpium and for the polyphyletic origin of Ascyreia, Hypericum, Taeniocarpium, Myriandra and Adenosepalum. The earlier evolutionary hypotheses concerning the origin of H. balearicum and H. calycinum, and the relatedness of Adenosepalum representatives, are not supported by our data analysis. The obtained results encourage the use of ITS sequence analysis in resolving the phylogenetic relationships within the member-rich genus Hypericum.
