New combinations and names in Lysimachia (Myrsinaceae) for species of Anagallis, Pelletiera and Trientalis

Manns U. & Anderberg A. A.: New combinations and names in Lysimachia (Myrsinaceae) for species of Anagallis, Pelletiera and Trientalis. — Willdenowia 39: 49–54. — Online ISSN 1868-6397; © 2009 BGBM Berlin-Dahlem. doi:10.3372/wi.39.39103 (available via http://dx.doi.org/) New combinations are proposed for species of Anagallis, Pelletiera and Trientalis in accordance with the results of phylogenetic analyses of the Lysimachia complex, based on molecular and morphological data. These three genera as well as Glaux and Asterolinon, for the species of which names in Lysimachia are already available, have been found to be derived, specialized groups that have evolved within Lysimachia. The present classification therefore does not reflect our current understanding of evolutionary relationships within the Lysimachia complex. Merging all the genera in Lysimachia is here considered better than splitting the latter into several smaller genera. For Anagallis crassifolia and A. filifolia new names are validated and for A. alternifolia and A. pumila the names change since their epithets have already been used in Lysimachia. Lectotypes are selected for A. filifolia, A. filiformis, A. kingaënsis, A. monelli, A. schliebenii, A. serpens and Pelletiera verna, and a neotype is designated for A. foemina.
