Two species of the Calcarata species complex of Viola section Melanium have been hypothesized to be of polyploid hybrid origin. To test this hypothesis, we used a modified restriction site associated (RAD) DNA-sequencing approach along with ITS and plastid DNA sequence data for reconstructing and dating the phylogeny of the group. For the detection...
Saxifraga section Saxifraga subsection Arachnoideae is a lineage of 12 species distributed mainly in the European Alps. It is unusual in terms of ecological diversification by containing both high elevation species from exposed alpine habitats and low elevation species from shady habitats such as overhanging rocks and cave entrances. Our aims are t...
The 22nd edition of the Rothmaler field flora was published in 2021, and the present article gives comments on the numerous, especial major changes. We added new species, and for the first time included an Algae group; the stoneworts, Characeae, which in many practical respects resemble vascular plants. For all species, biological data were revised...
Die Sand-Quecke, Elymus arenosus, ist eine in ihrer Umgrenzung, taxonomischen Bewertung und geographischen Verbreitung umstrittene Art. Während einige Autoren sie als Endemiten des Mainzer Sandes betrachten, wird sie von anderen Autoren, häufig als Unterart, als auch an den Küsten Nordwesteuropas weitverbreitet aufgefasst. Unter Verwendung von plas...
Die Sand-Lotwurz, Onosma arenaria, kommt in Deutschland nur im Gebiet des Mainzer Sandes vor. Es wird allgemein angenommen, dass das Vorkommen der Art hier als Restvorkommen einer nacheiszeitlich weiter ausgedehnten, heute südosteuropäischen Steppe interpretiert werden muss. Jüngere Untersuchungen haben gezeigt, dass O. helvetica aus der südwestlic...
Colobanthus (23 species) and Sagina (30–33 species) together are sister to Facchinia. Whereas Facchinia is distributed in western Eurasia, Colobanthus is almost exclusively distributed in the Southern Hemisphere, and Sagina is distributed in both hemispheres with the highest species diversity in western Eurasia. We examined: 1. Whether Sagina and C...
Analysing multiple genomic regions while incorporating detection and qualification of discordance among regions has become standard for understanding phylogenetic relationships. In plants, which usually have comparatively large genomes, this is feasible by the combination of reduced-representation library (RRL) methods and high-throughput sequencin...
Tephroseris is generally considered a difficult genus. Based on the examination of extensive herbarium material and considering the existing literature, we recognize seven species in Europe outside Russia. These are T. palustris, T. integrifolia with subsp. integrifolia, subsp. aurantiaca, subsp. capitata, subsp. maritima, subsp. serpentini and sub...

Scrophularia neesii und S. umbrosa ließen sich durch relative Messung des DNA-Gewichtes mit Durchflusszytometrie sicher unterscheiden. Hybriden wurden nicht gefunden. S. neesii ist die weiter verbreitete Sippe mit einem Vorkommensschwerpunkt in Süddeutschland sowie in Teilen Westdeutschlands, S. umbrosa ist dagegen in Norddeutschland die häufigere...
The ongoing paradigm shift in taxonomy from individual contributions to a truly collaborative and forward-looking endeavour results in a number of challenges related to distributed data management. Examination of physical specimens remains a key task, but searching for specimen data, literature, and name information is now mostly done online. In th...
Premise of the Study
Recurrent formation of polyploid taxa is a common observation in many plant groups. Haploid, cytoplasmic genomes like the plastid genome can be used to overcome the problem of homeologous genes and recombination in polyploid taxa. Fragaria (Rosaceae) contains several octo‐ and decaploid species. We use plastome sequences to inf...
The nomenclatural change Mononeuria caroliniana comb. nov. is proposed on the basis of molecular phylogenetic results analyzing the nuclear internal transcribed spacer.
Sabulinabasaltica and Sabulinasororia (Caryophyllaceae) are described as new species endemic to Washington State, U.S.A. Sabulinabasaltica is restricted to high-elevation, basalt rocks in the northeastern Olympic Mountains, and Sabulinasororia to high-elevation, dunite rocks of the Twin Sisters Range in the North Cascade Mountains. Both were previo...

Cherleria sedoides, a plant species widespread in alpine areas of the major European mountain ranges and in Scotland, contains two highly divergent chloroplast haplotype groups, one widespread (WH) and one present only in some populations in the Alps (AH). We investigated whether this haplotype diversity is the result of (1) intraspecific different...
Minuartia s.l. (Caryophyllaceae) is polyphyletic, with its species belonging to eleven major clades, all of which have been recognized at the generic rank. Cherleria is one of these segregate genera, based on the Linnaean species Cherleria sedoides. Its centre of diversity is on the Balkan Peninsula, but species also occur in the European and North...
Understanding the relative importance of different mechanisms of speciation in a given lineage requires fully resolved interspecific relationships. Using Facchinia, a genus of seven species centred in the European Alps, we explore whether the polytomy found by Sanger sequencing analyses of standard nuclear (ITS) and plastid markers (trnQ-rps16) is...
Adenostyles Cass. (Asteraceae, Senecioneae) is an endemic genus of Europe, prevalently distributed throughout the Alps, but with its range extends also to northern Spain, the Balkans, Corsica, doubtfully Greece, and along the entire Apennine chain in Italy, including the mountains of Calabria and Sicily (1). Within this genus, particularly interest...
Decreasing plant size with increasing latitude or altitude is a commonly observed pattern. Among the four genera of the Petasites-clade (Asteraceae–Senecioneae), Petasites and Tussilago, widespread throughout the Northern Hemisphere, mostly have large leaves and many capitula, whereas Homogyne and Endocellion from alpine and arctic environments hav...
The use of DNA sequence data in plant systematics has brought us closer than ever to formulating well-founded hypotheses about phylogenetic relationships, and phylogenetic research keeps on revealing that plant genera as traditionally circumscribed often are not monophyletic. Here, we assess the monophyly of genera documented in Rothmaler's "Exkurs...

Cherleria sedoides L. (Minuartia sedoides (L.) Hiern) is a montane perennial which, with some species in Minuartia sect. Spectabiles, is more closely related to Scleranthus than to other Minuartia species and is therefore best restored to the reinstated and redefined genus Cherleria. Reconstruction of the ancestral area of the clade containing C. s...
Minuartia is one of the larger genera of Caryophyllaceae with about 175 species distributed mainly in the Northern Hemisphere. The taxonomy of the genus has been studied by several authors, resulting in the recognition of numerous infrageneric groups. Previous phylogenies of the Caryophyllaceae showed that Minuartia is polyphyletic, but included on...

Premise of the study:
Heterogeneity of edaphic conditions plays a large role in driving the diversification of many plant groups. In the Alps and other European high mountains, many closely related calcicole and calcifuge plant taxa exist. To better understand patterns and processes of edaphic differentiation, the phylogeny of the...
