F. 2015: Lactuca tatarica (Asteraceae) in embryonic dunes on Wolin Island (NW Poland). – Biodiv. Res. Conserv. 39: 61–66. Abstract: “By the end of the 19th century, Lactuca tatarica was reported for the first time from an adventive occurrence on the North Sea and Baltic Sea coasts. In Wolin Island, the species has become established in the natural habitat and is clearly spreading in recent years. The community with L. tatarica was studied currently on the western point of Wolin Island along the stretch between the mouth of the Świna (Swine) River and a newly constructed breakwater of the external harbour. The taxon occupies relatively low parts of the sandy elevations of dune ridges, in patches of the Honckenyo-Agropyretum juncei association (habitat 2110). Furthermore, L. tatarica has been reported in recent years from some locations in Świnoujście (Usedom (Uznam) Island), Międzyzdroje, Wisełka and Międzywodzie.” –––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 18 July 2016 Gültepe M., Coşkunçelebı K., Makbul S. & Coşkun S. 2015: Tragopogon turcicus sp. nov. (Asteraceae) from Turkey and its phylogenetic position. – Nordic J. Bot. 33: 540–547. Abstract: “Tragopogon turcicus Coşkunç., M.Gultepe & Makbul, a new diploid species (2n = 2x = 12), is described and illustrated from Kızıldağ National Park (Isparta), southwest Anatolia. It is morphologically similar to T. oligolepis Hartvig & Strid which is also endemic to Turkey. Diagnostic characters, description, conservation status together with micro- and macro-morphological properties of achenes and pollen grains are given. A phylogenetic analysis based on nrDNA ITS sequence data indicated that T. oligolepis is the sister species of the new taxon.” –––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 18 July 2016 Di Gristina E., Raimondo F.

Abstract: “In phylogeography, DNA sequence and fingerprint data at the population level are used to infer evolutionary histories of species. Phylogeography above the species level is concerned with the genealogical aspects of divergent lineages. Here, we provide a phylogeographic study to examine the evolutionary history of a western Mediterranean composite, focusing on the perennial species of Helminthotheca ( Asteraceae, Cichorieae). We used molecular markers (AFLP; ITS and plastid DNA sequences) to infer relationships among populations throughout the distributional range of the group. Interpretation is aided by biogeographic and molecular clock analyses. Four coherent entities are revealed by Bayesian mixture clustering of AFLP data, which correspond to taxa previously recognized at the rank of subspecies. The origin of the group was in western North Africa, from where it expanded across the Strait of Gibraltar to the Iberian Peninsula and across the Strait of Sicily to Sicily. Pleistocene lineage divergence is inferred within western North Africa as well as within the western Iberian region. The existence of the four entities as discrete evolutionary lineages suggests that they should be elevated to the rank of species, yielding H. aculeata, H. comosa, H. maroccana and H. spinosa, whereby the latter two necessitate new combinations.” ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 18 December 2015 Meyer N., Gottschlich G. & Reisch C. 2015: Neue Hieracium-Taxa aus dem südöstlichen Frankenjura. – Ber.

Abstract: “PREMISE OF THE STUDY: The high biodiversity in the Baetic-Rifan hotspot of Mediterranean region is shaped by complex geological and climatic histories and has been a subject of recent intensive studies. However, very little is known about phylogenetic and biogeographic history of three rare and critically endangered cliff-dwelling species of Sonchus in section Pustulati in this region. METHODS: We investigated the genetic variation and phylogenetic relationships of populations based on nuclear (ITS/ETS) and plastid (3′trnL–ndhJ/psaI–accD) DNA sequences, and amplified fragment length polymorphisms (AFLPs). We performed a Bayesian relaxed molecular clock analysis with ITS data to estimate divergence times for major lineages. KEY RESULTS: ITS/ETS and AFLP phylogenies showed high concordance and contrasted with cpDNA data. The divergence between S. masguindalii and S. fragilis was dated at 5.48 Ma, between S. fragilis and S. pustulatus at 3.89 Ma, and between the Baetic and Rifan S. pustulatus at 1.18 Ma. Within each distribution area, AFLP data showed a relatively high genetic structuring and moderate genetic diversity, the latter being impoverished in the Baetic populations. CONCLUSIONS: Our results further confirm the hybrid origin of S. pustulatus, a critically endangered species. The origin and diversification of lineages appear to have occurred on the temporary land bridge that joined Iberian and North Africa during the Messinian Salinity Crisis (5.96–5.33 Ma) and the subsequent Zanclean flood that progressively refilled the Mediterranean Basin (5.33–3.60 Ma). The only Baetic populations of S. pustulatus most likely originated from the Rifan ones.” ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 10 December 2015 Wilschut R. A., Oplaat C., Snoek L. B., Kirschner J. & Verhoeven K. J. F. 2015: Natural epigenetic variation contributes to heritable flowering divergence in a widespread asexual dandelion lineage. – Molec. Ecol. DOI: 10.1111/mec.13502. Abstract: “Epigenetic variation has been proposed to contribute to the success of asexual plants, either as a contributor to phenotypic plasticity or by enabling transient adaptation via selection on transgenerationally stable, but reversible, epialleles. While recent studies in experimental plant populations have shown the potential for epigenetic mechanisms to contribute to adaptive phenotypes, it remains unknown if heritable variation in ecologically relevant traits is at least partially epigenetically determined in natural populations. Here, we tested the hypothesis that DNA methylation variation contributes to heritable differences in flowering time within a single widespread apomictic clonal lineage of the common dandelion (Taraxacum officinale s. lat.). Apomictic clone members of the same apomictic lineage collected from different field sites showed heritable differences in flowering time, which was correlated with inherited differences in methylation-sensitive AFLP marker profiles. Differences in flowering between apomictic clone members were significantly reduced after in vivo de-methylation using the DNA methyltransferase inhibitor zebularine. This synchronization of flowering times suggests that flowering time divergence within an apomictic lineage was mediated by differences in DNA methylation. While the underlying basis of the methylation polymorphism at functional flowering time-affecting loci remains to be demonstrated, our study shows that epigenetic variation contributes to heritable phenotypic divergence in ecologically relevant traits in natural plant populations. This result also suggests that epigenetic mechanisms can facilitate adaptive divergence within genetically uniform asexual lineages.” ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 10 December 2015 McCosh D.

Resoucres Crop Evol.​1007/​s10722-015-0332-5. Abstract: “Lettuce (Lactuca sativa L.) belongs to the genus Lactuca L. and is an important vegetable worldwide. Over the past decades, there have been many controversies about the phylogeny of Lactuca species due to their complex and diverse morphological characters and insufficient molecular sampling. In this study we provide the most extensive molecular phylogenetic reconstruction of Lactuca, including African wild species, using two chloroplast genes (ndhF and trnL-F). The sampling covers nearly 40 % of the total endemic African Lactuca species and 34 % of the total Lactuca species. DNA sequences from all the subfamilies of Asteraceae in Genebank and those generated from Lactuca herbarium samples were used to establish the affiliation of Lactuca within Asteraceae. Based on the subfamily tree, we selected 33 ndhF sequences from 30 species and 79 trnL-F sequences from 48 species to infer relationships within the genus Lactuca using randomized axelerated maximum likelihood and Bayesian inference analyses. Biogeographical, chromosomal and morphological character states were reconstructed over the Bayesian tree topology. We conclude that Lactuca contains two distinct phylogenetic clades—the crop clade and the Pterocypsela clade. Other North American, Asian and widespread species either form smaller clades or mix with the Melanoseris species. The newly sampled African endemic species probably should be treated as a new genus.” ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 3 November 2015 Szeląg Z. 2015: Hieracia balcanica XI.

This indicates a high probability of their capacity for seed reproduction by apomixis. The capacity of these species for seed production by apomixis was confinned under pollenless mode of flowering. The frequency of indicating the cytoembryologic signs of apomixis and seed formation by apomixis varies considerably in different years and in different populations. C. ambigua is found to be sexual, and characterized by low level of pollen defects, the lack of megagametophytes with marker signs of apomixis, and lack of seeds at pollenless mode of flowering.” ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 6 October 2015 Ferrer-Gallego P.

Abstract: “Populations of polyploid apomictic dandelions consist of a mixture of clonal genotypes that are nearly phenotypically and genetically uniform. Some apomictic taxa are widespread, but many other taxa occur locally or at a single locality. Additionally, certain Central European dandelion populations consist of both diploid sexuals and polyploid apomicts, and the gene flow expected in mixed populations obscures clear genetic and morphological borders among apomictic taxa. In the present study, we investigated genotypic diversity among seven apomictic microspecies coexisting in Central Europe. Using microsatellites, amplified fragment length polymorphism and chloroplast DNA markers, we focused on the clonal structure of apomictic taxa, i.e., whether the studied apomictic taxa are represented by one or a few related genotypes or whether they are represented by many different and unrelated genotypes. The pattern of genotypic diversity within the studied microspecies suggests both intra- and inter-specific genetic diversification. At the intra-specific level, the studied apomictic taxa consist of several related genotypes, and difference among these genotypes is the result of somatic mutations and/or the consequence of repeated origin from different lineages or recent hybridisation. The inter-specific genetic diversity is greater and may reflect a different evolutionary origin of apomictic taxa. Our results show that despite their increased genetic diversity, apomictic dandelions form definable clusters that may be characterised by both molecular markers and morphology.” ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 5 October 2015 Crawford D.

E. 2015: Breeding systems in Tolpis (Asteraceae) in the Macaronesian islands: the Azores, Madeira and the Canaries. – Pl. Syst. Evol. 301: 1981–1993. Abstract: “Plants on oceanic islands often originate from self-compatible (SC) colonizers capable of seed set by self-fertilization. This fact is supported by empirical studies, and is rooted in the hypothesis that one (or few) individuals could find a sexual population, whereas two or more would be required if the colonizers were self-incompatible (SI). However, a SC colonizer would have lower heterozygosity than SI colonizers, which could limit radiation and diversification of lineages following establishment. Limited evidence suggests that several species-rich island lineages in the family Asteraceae originated from SI colonizers with some “leakiness” (pseudo-self-compatibility, PSC) such that some self-seed could be produced. This study of Tolpis ( Asteraceae) in Macaronesia provides first reports of the breeding system in species from the Azores and Madeira, and additional insights into variation in Canary Islands. Tolpis from the Azores and Madeira are predominately SI but with PSC. This study suggests that the breeding systems of the ancestors were either PSC, possibly from a single colonizer, or from SI colonizers by multiple disseminules either from a single or multiple dispersals. Long-distance colonists capable of PSC combine the advantages of reproductive assurance (via selfing) in the establishment of sexual populations from even a single colonizer with the higher heterozygosity resulting from its origin from an outcrossed source population. Evolution of Tolpis on the Canaries and Madeira has generated diversity in breeding systems, including the origin of SC. Macaronesian Tolpis is an excellent system for studying breeding system evolution in a small, diverse lineage.” ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 28 September 2015 Di Gristina E., Gottschlich G. & Raimondo F.M. 2015: Hieracium hypochoeroides subsp. peracutisquamum (Asteraceae), a new taxon from Basilicata, southern Italy. – Ann.

Abstract: “PREMISE OF THE STUDY: The high biodiversity in the Baetic-Rifan hotspot of Mediterranean region is shaped by complex geological and climatic histories and has been a subject of recent intensive studies. However, very little is known about phylogenetic and biogeographic history of three rare and critically endangered cliff -dwelling species of Sonchus in section Pustulati in this region. METHODS: We investigated the genetic variation and phylogenetic relationships of populations based on nuclear (ITS/ETS) and plastid (3′trnL–ndhJ/psaI–accD) DNA sequences, and amplified fragment length polymorphisms (AFLPs). We performed a Bayesian relaxed molecular clock analysis with ITS data to estimate divergence times for major lineages. KEY RESULTS: ITS/ETS and AFLP phylogenies showed high concordance and contrasted with cpDNA data. The divergence between S. masguindalii and S. fragilis was dated at 5.48 Ma, between S. fragilis and S. pustulatus at 3.89 Ma, and between the Baetic and Rifan S. pustulatus at 1.18 Ma. Within each distribution area, AFLP data showed a relatively high genetic structuring and moderate genetic diversity, the latter being impoverished in the Baetic populations. CONCLUSIONS: Our results further confirm the hybrid origin of S. pustulatus, a critically endangered species. The origin and diversifi cation of lineages appear to have occurred on the temporary land bridge that joined Iberian and North Africa during the Messinian Salinity Crisis (5.96–5.33 Ma) and the subsequent Zanclean flood that progressively refi lled the Mediterranean Basin (5.33–3.60 Ma). The only Baetic populations of S. pustulatus most likely originated from the Rifan ones.” ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 11 September 2015 Talukdar T. 2015: Comparative investigations on fruit microcharacters of four species of Hieracium L.

Abstract: “The phytosociology and ecology of Scorzonera parviflora stands were studied in the Pannonian Basin and Western Balkans. In total, we used 60 relevés (46 collected for this study and 14 from the literature) for the ordination analysis. Optimal conditions for S. parviflora are species-poor coastal habitats in regions with hot summers and with high soil salinity and nutrient-richness. The species reached high cover values in most cases (25–50 %) and it often dominated the stand. The classification of phytosociological data shows four floristically and ecologicaly well characterized clusters. Cluster 1 was identified as the rare association Junco maritimi-Scorzoneretum parviflorae, sampled only in coastal Croatia (on the island of Pag) and inland Hungary (Fertőszéplak). Cluster 2 groups meadow-like salt marsh vegetation in transition between two vegetation types, Limonio narbonensis-Puccinellietum festuciformis and Trifolio-Hordeetum secalini. Cluster 3 represents the typical variant of the Scorzonero parviflorae-Juncetum gerardii, while cluster 4 was determined as a variant with Tripolium pannonicum of the Scorzonero parviflorae-Juncetum gerardii characterized by a higher presence of obligate halophytes (Tripolium pannonicum, Puccinellia distans agg. and Plantago maritima) than in cluster 3. Our study shows that vegetation with Scorzonera parviflora in inland Central and SE Europe belongs to the Juncion gerardii and stands of coastal Croatia are related to the Juncion maritimi alliance. The species composition and the classification of the examined stands in the Pannonian and Transylvanian basins were influenced more by abiotic environmental factors than by current management.” ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 12 August 2015 Moffat, C.

Bot. 102: 1145–1159 Abstract: “• Premise of the study: Accurate assessments of biodiversity are paramount for understanding ecosystem processes and adaptation to change. Invasive species often contribute substantially to local biodiversity; correctly identifying and distinguishing invaders is thus necessary to assess their potential impacts. We compared the reliability of morphology and molecular sequences to discriminate six putative species of invasive Pilosella hawkweeds (syn. Hieracium, Asteraceae), known for unreliable identifications and historical introgression. We asked (1) which morphological traits dependably discriminate putative species, (2) if genetic clusters supported morphological species, and (3) if novel hybridizations occur in the invaded range. • Methods: We assessed 33 morphometric characters for their discriminatory power using the randomForest classifier and, using AFLPs, evaluated genetic clustering with the program structure and subsequently with an AMOVA. The strength of the association between morphological and genotypic dissimilarity was assessed with a Mantel test. • Key results: Morphometric analyses delimited six species while genetic analyses defined only four clusters. Specifically, we found (1) eight morphological traits could reliably distinguish species, (2) structure suggested strong genetic differentiation but for only four putative species clusters, and (3) genetic data suggest both novel hybridizations and multiple introductions have occurred. • Conclusions: (1) Traditional floristic techniques may resolve more species than molecular analyses in taxonomic groups subject to introgression. (2) Even within complexes of closely related species, relatively few but highly discerning morphological characters can reliably discriminate species. (3) By clarifying patterns of morphological and genotypic variation of invasive Pilosella, we lay foundations for further ecological study and mitigation.” ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 8 July 2015 Ferreira M.

Jr. & Fehrer J. 2015: Tracing the evolutionary history of the little-known Mediterranean-Macaronesian genus Andryala (Asteraceae) by multigene sequencing. – Taxon 64: 535–551. Abstract: “Andryala ( Asteraceae: Cichorieae) is a little-known Mediterranean-Macaronesian genus whose taxonomy is much in need of revision. In order to elucidate species relationships in the genus, we performed phylogenetic analyses of nucleotide sequences of the internal transcribed spacers (ITS) and the external transcribed spacer (ETS) of nuclear ribosomal DNA (nrDNA), two chloroplast (cpDNA) markers (trnT-trnL and trnV-ndhC intergenic spacers), and one single-copy nuclear gene (sqs) using Bayesian and maximum parsimony methods of inference. While cpDNA analysis confirmed a previously inferred chloroplast capture event with the sister genus Pilosella, all nuclear markers supported the monophyletic origin of Andryala. However, determining accurate phylogenetic relationships within the genus was quite challenging due to very low levels of nucleotide divergence of all nrDNA and cpDNA markers and a high degree of homoplasy and incomplete lineage sorting in the variable sqs marker. Although none of the phylogenies were well resolved, all markers identified two well-supported basal lineages corresponding to the relict species A. agardhii (Spain, Morocco) and A. laevitomentosa (Romania). The remaining Andryala taxa under study, whose relationships were largely unresolved, formed a well-supported clade (“Major Radiation Group”). The capacity of the markers to resolve taxonomic entities within this group varied. While congruent genetic evidence was found for some taxa, several morphologically unambiguous species could not be distinguished at all with most or even all markers. The extremely low level of genetic divergence among most of the species, in spite of high morphological diversity, along with a basal polytomy found with all markers, suggests their relatively recent and rapid speciation. Phylogenetic analyses of the single-copy marker advocate for a single colonization event of the common ancestor of two endemic species (A. glandulosa, A. crithmifolia) from the Mediterranean region to Madeira and that of two other endemics (A. perezii, A. pinnatifida) to the Canary Islands. The frequently observed evolutionary pattern of continental dispersion followed by insular speciation also holds for Andryala.” ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 6 July 2015 Enke N., Kunze R., Pustahija F., Glöckner G., Zimmermann J., Oberländer J., Kamari G. & Siljak-Yakovlev S. 2015: Genome size shifts: karyotype evolution in Crepis section Neglectoides (Asteraceae). – Pl. Biol. Abstract: Plant genome size evolution is a very dynamic process: the ancestral genome of angiosperms was initially most likely small, which led to a tendency towards genome increase during evolution. However, findings in several angiosperm lineages demonstrate mechanisms that also led to genome size contraction. Recent molecular investigations on the Asteraceae genus Crepis suggest that several genomic reduction events have occurred during the evolution of the genus. This study focuses on the Mediterranean Crepis sect. Neglectoides, which includes three species with some of the smallest genomes within the whole genus. Crepis neglecta has the largest genome in sect. Neglectoides, approximately twice the size of the two species Crepis cretica and Crepis hellenica. Whereas C. cretica and C. hellencia are more closely related to each other than to C. neglecta the karyotypes of the latter species and C. cretica are similar, while that of C. hellenica differs considerably. Here, the karyotypic organisation of the three species is investigated with fluorescence in-situ hybridisation and studied in a molecular phylogenetic framework based on the nuclear markers Actin, CHR12, CPN60B, GPCR1 and XTH23. Our findings further corroborate the occurrence of genome size contraction in Crepis, and suggest that the difference in genome size between C. neglecta and C. cretica is mostly due to elimination of dispersed repetitive elements, whereas chromosomal reorganisation was involved in the karyotype formation of C. hellenica. ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 26 June 2015 Altinordu F., Martın E., Makbul S., Çoşkunçelebı K. & Gültepe M. 2015: Cytogenetic studies on some Scorzonera L. s.l.

Although there is a considerable amount of data regarding germination in the genus Lactuca, little is known about seed germination in L. watsoniana, which is an important gap for defining conservation strategies. Seed viability (tetrazolium test) declined from 100 to 30% after four months storage at room temperature over silica gel. We tested the effects of 1) incubation temperature (three alternating temperature regimes); 2) gibberellic acid concentration (four levels); 3) addition of ethephon; and 4) type of light (three modalities) on seed germination (fresh seeds). There was a significant effect of incubation temperature, gibberellic acid concentration and type of light on percentage germination. There were also significant interaction effects of gibberellic acid with all the other studied factors, and the type of light with temperature regime. The optimal treatment was 0.1 mg l-1 gibberellic acid, ethephon and a red filter at 15/10 °C, resulting in 95% germination.

M. 2015: Are Cichorieae an indicator of open habitats and pastoralism in current and past vegetation studies? – Pl. Biosystems 149: 154–165. Abstract: Cichorieae, one of the six tribes of the sub-family Cichorioideae ( Asteraceae), produces a well-recognisable fenestrate pollen type. In the Mediterranean area, the significance of high percentages of Cichorieae pollen from archaeological layers is still questioned. We assessed the presence of Cichorieae as indicators of open habitats and pasturelands in current plant communities by comparing data on vegetation composition with pollen spectra from two Hellenistic sites of Basilicata (southern Italy): Difesa San Biagio in the low valley of the river Bradano and Torre di Satriano in the Lucanian Apennines. We also analysed the pollen morphology bringing to the discrimination of size classes within the fenestrate type of Cichorieae. Pollen spectra from the considered archaeological sites have low forest cover (7% on average); Asteraceae and Poaceae are prevalent; Cichorieae account to ca. 23%; coprophilous fungal spores are varied and present high concentrations. In surface soil samples collected near the sites, Cichorieae pollen is about 12%. In current vegetation types, an increasing abundance of Cichorieae was observed from salt marshes, forests and shrublands to open habitats and grasslands. This is coherent with the actual land cover around the study sites and the findings of the archaeological sample that point to an open landscape dominated by pastures and cultivated fields. Our integrated approach confirmed that today Cichorieae are common in secondary pastures and in some types of primary open habitats of southern Italy: hence, high percentages of this pollen can be considered a good indicator of these habitats even in past environment reconstructions. ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 10 June 2015 Moura M., Silva L., Dias E.

Abstract: Two endemic species of Leontodon are currently recognized in the Azores archipelago: Leontodon filii and L. rigens. However, there has been confusion regarding the application of these names and field observations and herbarium studies suggested three morphotypes in the islands. Here, we present a taxonomic revision of the Azorean endemic Leontodon species using morphological characters and new molecular data from the ITS region and from three chloroplast regions: trnQ, trnV and matK. Fifty-one quantitative and qualitative morphological characters were examined that revealed consistent differences between specimens from the western, central and eastern subarchipelagos (where, on the latter, Leontodon is restricted to São Miguel). Molecular analysis revealed two well defined monophyletic groups, one comprising accessions from São Miguel and the second comprising accessions from the western group, while central group accessions were in an unresolved polytomy. Both analyses also indicated the occurrence of hybridization with L. saxatilis, a widespread non-endemic species. Taken together, molecular and morphological data suggest the reinstatement of a third Azorean Leontodon taxon endemic to the western group.

Bot. 102: 634–641.

Abstract: Premise of the study: Endemic plants on oceanic islands have long served as model systems for studying patterns and processes of evolution. However, phylogenetic studies of island plants frequently illustrate a decoupling of molecular divergence and ecological/morphological diversity, resulting in phylogenies lacking the resolution required to interpret patterns of evolution in a phylogenetic context. The current study uses the primarily Macaronesian flowering plant genus Tolpis to illustrate the utility of multiplexed shotgun genotyping (MSG) for resolving relationships at relatively deep (among archipelagos) and very shallow (within archipelagos) nodes in this small, yet diverse insular plant lineage that had not been resolved with other molecular markers.

Methods: Genomic libraries for 27 accessions of Macaronesian Tolpis were generated for genotyping individuals using MSG, a form of reduced-representation sequencing, similar to restriction-site-associated DNA markers (RADseq). The resulting data files were processed using the program pyRAD, which clusters MSG loci within and between samples. Phylogenetic analyses of the aligned data matrix were conducted using RAxML.

Key results: Analysis of MSG data recovered a highly resolved phylogeny with generally strong support, including the first robust inference of relationships within the highly diverse Canary Island clade of Tolpis.

Conclusions: The current study illustrates the utility of MSG data for resolving relationships in lineages that have undergone recent, rapid diversification resulting in extensive ecological and morphological diversity. We suggest that a similar approach may prove generally useful for other rapid plant radiations where resolving phylogeny has been difficult. ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 19 May 2015 Roma-Marzio F., Astuti G. & Peruzzi L. 2015: Taxonomy, typification and karyology of Crepis lacera (Asteraceae). – Phytotaxa 208: 45–54.

F. 2015: Population genetic structure of the South American species Hypochaeris lutea (Asteraceae). – Pl. Sp. Biol. doi: 10.1111/1442-1984.12084 Abstract: The genus Hypochaeris has a recent evolutionary history caused by long-distance dispersal in conjunction with adaptive radiation in the South American continent. Hypochaeris lutea is a perennial herb that grows mostly at altitudes of around 1000 m in cold swamps of the southern regions of Brazil. We investigated the amplified fragment length polymorphism (AFLP) in 270 individuals representing 11 Brazilian populations of H. lutea to elucidate the population genetic structure of this species. The frequencies of polymorphic loci and gene diversity ranged from 83.42% to 91.66% and from 0.26 to 0.34, respectively. Analysis of molecular variance revealed that most of the genetic variability was found within (76.67%) rather than among (23.3%) populations, agreeing with the pattern of genetic distribution within and among populations observed in other allogamous species of Hypochaeris. A Mantel test showed no correlation between genetic and geographic distances when all populations were considered. Simulations performed using a Bayesian approach consistently identified two clusters with different admixture proportions of individuals, as also revealed by a UPGMA dendrogram of populations. The pattern of genetic structure observed in H. lutea is consistent with a process of successive colonization events by long-distance dispersal resembling the rapid and recent radiation that has been proposed to explain the origin of the South American species of Hypochaeris. ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 16 April 2015 Zeisek V., Kirschner J., Štěpánek J. & Amini Rad M. 2015: Microsatellite variation, sexual reproduction and taxonomic revision of Taraxacum sect. Dioszegia: relationships at a large spatial scale. – Preslia 87: 55–85. Abstract: The coexistence of agamospermy and sexuality characterizes most of the ~60 sections of the genus Taraxacum. Section Dioszegia, comprising T. serotinum and its allies, are an exception because only sexuals are reported for all the members of this group. On the basis of the analysis of microsatellite (SSRs) variation, distribution and morphology, we addressed problems related to their mode of reproduction, among-population relationships, taxonomy and within-population variation, using samples from populations in an area extending from southern France to the European part of southern Russia and Iran. We found strong isolation by distance and deep spatio-temporal structure among populations. As a rule, outcrossing was the dominant mode of reproduction, with one notable exception: T. serotinum subsp. tomentosum (≡ T. pyrrhopappum) was autogamous and not heterozygous. This subspecies is understood as a relic of a continental migration of T. serotinum in the late glacial/early post-glacial period, which became autogamous. Taraxacum haussknechtii is relatively highly heterozygous with a high degree of connectivity among populations, whereas populations of T. serotinum subsp. serotinum show high level of inter-population variability. A taxonomic revision of sect. Dioszegia recognizes T. serotinum subsp. serotinum (including an aberrant taxon, newly described as var. iranicum), T. serotinum subsp. tomentosum and T. haussknechtii. Full synonymy was compiled and lectotypes designated for six names. A list of the herbarium material studied is given for the latter three taxa, and a distribution map is provided for T. haussknechtii. ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 16 April 2015 Di Gristina E., Gottschlich G. & Raimondo F.

Abstract: Hieracium sartorianum var. lucanicum, a little known taxon described from Mt Sacro (Parco Nazionale del Cilento e Vallo di Diano, Prov. of Salerno, Campania, Italy), is reexamined. As a result it is reclassified as a subspecies to H. hypochoeroides. A new combination and lectotypification are made and a detailed description is given. ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 26 March 2015 Thompson I.

Abstract: “Results from barcoding studies of tribe Cichorieae for the Tennessee flora using data from the nuclear ribosomal ITS marker region are presented and include first complete reports of this marker for 15 of the 24 species of the tribe that are native to the state. Sequence data from the ITS region separated all genera of Cichorieae in Tennessee from one another, and almost all species of the introduced Cichorium, Crepis, Hypochaeris, Lapsana, Leontodon, and Hieracium subgen. Pilosella from one another. In contrast, many (though not all) species of the native members of Hieracium, Krigia, Lactuca, and Nabalus were not uniquely distinguished by this marker. ITS sequence data provided support for the recognition of Nabalus as distinct from Prenanthes, and helped to confirm the identification of N. albus samples newly reported for Tennessee. ITS sequence data also suggested that N. cylindricus may represent a species distinct from N. roanensis, with which it has been lumped. The results of this study suggest that further study is needed to clarify patterns of diversification in the four genera of Cichorieae that exhibit radiations in southeastern North America. ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 9 March 2015 Øllgaard H. 2015: Twelve new native Taraxacum species from the Nordic countries. – Nordic J.

Erythrosperma), T. danicum (sect. Palustria), T. conspersum and T. lentiginosum (sect. Naevosa), T. pietii-oosterveldii (sect. Celtica) and T. ovillum (sect. Spectabilia). They are compared with morphologically similar species, and their ecological preferences are outlined. Known distribution areas and lists of paratypes are given. Taraxacum polyschistum Dahlst. forma oelandicum G. E. Haglund (sect. Erythrosperma) is given status of species. ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 9 March 2015 Sukhorukov A. P. & Nilova M. V. 2015: Carpology of the genus Tragopogon L. (Asteraceae). – Phytotaxa 201: 27–49. Abstract: 67 species of Tragopogon were investigated with regard to fruit anatomy. The outer achenes, especially the beak and the central part of the seed-containing body, provide the most valuable features (diameter and outlines of the body and the beak, and arrangement of the mechanical elements in the body parenchyma). Some specimens of widely distributed taxa (e.g. T. capitatus, T. dubius, T. pratensis, T. pseudomajor) show variation in the character set and require more investigation prior to further taxonomic treatment. The species studied are classified into informal groups to demonstrate the diversity of carpological traits within the genus, and a comparison is made with the existing molecular phylogeny. The separation of the genus Geropogon from Tragopogon is supported by the achene anatomy. ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 19 February 2015 Tyler T. & Sennikov A.

E. 2015: Multiple origins and chromosomal novelty in the allotetraploid Tragopogon castellanus (Asteraceae). – New Phytologist doi:10.1111/nph.13227. Abstract:

  • Tragopogon includes two classic examples of recently formed allopolyploid species in North America: T. mirus and T. miscellus. Older Tragopogon allotetraploids from Eurasia offer ideal taxa for comparing the longer term outcomes of allopolyploidy.
  • To help resolve the ancestry of one of these older polyploids, phylogenetic analyses of multiple populations of the allotetraploid T. castellanus (2 n = 24) and its putative diploid parents, T. crocifolius and T. lamottei, were conducted using sequences from nuclear (internal transcribed spacer, ITS; and alcohol dehydrogenase 1A, Adh) and plastid (trnT-trnL spacer, trnL intron, trnL-trnF spacer and rpl16 intron) loci. Fluorescence in situ hybridization (FISH) and genomic in situ hybridization (GISH) were used to investigate the chromosomal constitution of T. castellanus.
  • Our data confirm that the widely distributed T. crocifolius and the Iberian endemic, T. lamottei, are the diploid parents of T. castellanus, and that this polyploid formed at least three times.
  • One group of populations of T. castellanus is distinct in exhibiting two pairs of rearranged chromosomes. These data suggest that some of the chromosomal variants that originate in young polyploids (here, an intergenomic translocation) may become fixed in populations, contributing to novelty in older polyploid lineages. The geographical distributions of the allopolyploids and parents are also complex, with allotetraploid populations being disjunct from one or both of the most closely related diploid parental populations.
