Megjegyzések:	Nymphaea lotus L. is a tropical and subtropical species of waterlilies with an African distribution. A conspicuous satellite occurrence can be found in Europe in a thermal spring in NW Romania. This population (treated as var. thermalis (DC.) Tuzson) received much attention as a potential Tertiary relict in the flora of Europe, although its relict vs. planted nature has been part of great debate among scholars during the last 200 years. We revisit this question by using molecular phylogenetic methods to estimate the timing of divergence of this species, and put this population into a phylogeographic context by comparing it to samples coming from the whole area of the species. By using sequences of the nuclear and the plastid genome, we reconstructed the phylogeographic relationships within N. lotus with a haplotype network building approach, that identified a genetically distant lineage in western Africa, which we relate to N. zenkeri Gilg, the sister species of N. lotus. All the populations of N. lotus s.str. displayed genetic distance between each other except for the Egyptian and Romanian populations. On our dated phylogeny of the subgenus Lotus the separation between N. lotus and its sister species was found to be younger than the end of the Tertiary (1.26 Mya). These results clearly refute the Tertiary relict status of the European population of N. lotus.

Cím:	Molecular phylogenetics, seed morphometrics, chromosome number evolution and systematics of European Elatine L. (Elatinaceae) species / Gábor Sramkó, Attila Molnár V., János Pál Tóth, Levente Laczkó, Anna Kalinka, Orsolya Horváth, Lidia Skuza, Balázs András Lukács, Agnieszka Popiela

Megjegyzések:	The genus Elatine contains ca 25 species, all of which are small, herbaceous annuals distributed in ephemeral waters on both hemispheres. However, due a high degree of morphological variability (as a consequence of their amphibious life-style), the taxonomy of this genus remains controversial. Thus, to fill this gap in knowledge, we present a detailed molecular phylogenetic study of this genus based on nuclear (rITS) and plastid (accD-psaI, psbJ-petA, ycf6-psbM-trnD) sequences using 27 samples from 13 species. On the basis of this phylogenetic analysis, we provide a solid phylogenetic background for the modern taxonomy of the European members of the genus. Traditionally accepted sections of this tree (i.e. Crypta and Elatinella) were found to be monophyletic, only E. brochonii - found to be a basal member of the genus - has to be excluded from the latter lineage to enforce monophyly. A number of taxonomic conclusions can also be drawn: E. hexandra, an high-ploid species is most likely a stabilised hybrid between the main sections; E. ampylosperma merits full species status based on bothmolecular and morphological evidence; E. gussonei is a more widespread and genetically diverse species with two main lineages, and the presence of the Asian E. ambigua in the European flora is questionable. The main lineages recovered in this analysis are also supported by a number ofsynapomorphic morphological characters as well as uniform chromosome counts. Based on all the evidence presented here, two new subsections within Elatinella are described: Subsection Hydropipera consisting of temperate species of the section, and; Subsection Macropodae including the Mediterranean species of the section.
