- Earlier hypotheses of floral evolution in Lysimachia and related genera were tested by phylogenetic analysis of DNA sequences from the plastid gene ndhF. It is concluded that taxa with flowers provided with oil-producing trichomes are not advanced and buzz-polinated species with anther cone are not ancestral as earlier proposed. Instead, species of Lysimachia with buzz-pollinated flowers belong to one derived clade, species with flowers provided with nectar producing trichomes belong to another, both groups have evolved from yellow flowered oil-producing ancestors. We also show that Lysimachia and most of its subgenera as well as the genera Anagallis, Pelletiera and Asterolinon are paraphyletic or polyphyletic as presently circumscribed, and that Trientalis and a few American species of Lysimachia are the closest relatives of the other species of Lysimachia + Anagallis, Asterolinon, Pelleriera and Glaux. The subgeneric classification and the biogeographical patterns are briefly discussed.
