D’Andrea L., Meirmans P., Wiel C. van de, Guadagnuolo R., Treuren R. van, Kozlowski G., Nijs H. den & Felber F. 2016: Molecular biogeography of prickly lettuce (Lactuca serriola L.) shows traces of recent range expansion. – J. Heredity 108: 194–206.

Abstract
“Prickly lettuce (Lactuca serriola L., Asteraceae), a wild relative of cultivated lettuce, is an autogamous species which greatly expanded throughout Western and Northern Europe during the last 2 centuries. Here, we present a large-scale biogeographic genetic analysis performed on a dataset represented by 2622 individuals from 110 wild European populations. Thirty-two maternally inherited chloroplast RFLP-markers and 10 nuclear microsatellite loci were used. Microsatellites revealed low genetic variation and high inbreeding coefficients within populations, as well as strong genetic differentiation between populations, which was in accordance with the autogamous breeding system. Analysis of molecular variance based clustering indicated the presence of 3 population clusters, which showed strong geographical patterns. One cluster occupied United Kingdom and part of Northern Europe, and characterized populations with a single predominant genotype. The second mostly combined populations from Northern Europe, while the third cluster grouped populations particularly from Southern Europe. Kriging of gene diversity for L. serriola corroborated northwards and westwards spread from Central (Eastern) Europe. Significant lower genetic diversity characterized the newly colonized parts of the range compared to the historical ones, confirming the importance of founder effects. Stronger pattern of isolation by distance was assessed in the newly colonized areas than in the historical areas (Mantel’s r = 0.20). In the newly colonized areas, populations at short geographic distances were genetically more similar than those in the historical areas. Our results corroborate the species’ recent and rapid northward and westward colonization from Eastern Europe, as well as a decrease of genetic diversity in recently established populations.”

Crawford D. J., Hauber D. P., Borges Silva L., Menezes de Sequeira M., Moura M., Santos-Guerra A., Kelly J. K. & Mort M. E. 2016: Breeding relationships in Macaronesian Tolpis (Asteraceae-Cichorieae): F1 hybrid pollen fertility within and among populations from the Azores, Canary Islands, and Madeira. – Syst. Bot. 41: 881–893.

Abstract
“The pollen fertility of F1 hybrids, ranging from progeny within natural populations to synthetic hybrids between species of Tolpis from three archipelagos in Macaronesia, was determined. Pollen fertility of F1 hybrids of inter-archipelago crosses from the Azores, Canaries, and Madeira were generally lower than crosses between populations or species in the same archipelagos. Lower pollen fertility was pronounced in hybrids between plants from the Canaries and the other archipelagos, which is concordant with a more distant phylogenetic relationship between the Canaries, and the Azores and Madeira. Lower average pollen fertility was seen between plants from different as compared to the same clades in the Canary Islands. However, low pollen fertilities were also detected between plants from some populations/species in the same archipelagos, and even among progeny of individual maternal plants. Some hybrids with reduced fertility had meiotic irregularities, suggesting chromosomal rearrangements; in other cases meiosis appeared normal. Results indicate that postzygotic isolating factors evolved subsequent to the divergence of Tolpis in the three archipelagos, but there are hybrid sterility factors among plants within each of the archipelagos, and even within some natural populations. Phylogenetic relationships in the Canary Islands indicate that divergence has occurred within the last million years. Present results implicate postzygotic factors as reproductive barriers facilitating population divergence and speciation in Macaronesian Tolpis.

Abstract
“We studied historical and recent occurrence of halophilous dandelionTaraxacum bessarabicum (Hornem.) Hand.-Mazz. in Slovakia. Herbarium specimens from 16 public herbaria were revised and field research during 2010–2015 was carried out. In total, circa 60 localities were recorded, 29 sites are documented by herbarium vouchers and 31 sites were excerpted only from the literature and unpublished data. Only five locations were confirmed recently, therefore we suggest keep the listing of the species on the IUCN category EN (endangered). Concerning the phytosociological approach, four recent locations of T. bessarabicum were found in saline vegetation of the alliance Puccinellion limosae, whereas its past frequent occurrence in the alliance Juncion gerardii was failed to confirm. Synanthropic occurrence was observed in Košice along gravel roadsides, between panels and on the edges of parking places and footpaths in stands close to vegetation of alliance Dauco-Melilotion. Distribution map of the historical and recent distribution of the species is given.”

Abstract
Taraxacum zajacii is a pentaploid bog dandelion described in 2012. As other dandelions belonging to the section Palustria, it is an endangered species. In spring 2014, we performed field studies aimed at estimating the range and characterising sites of this taxon. Present range of the species includes 6 sites, all situated in Pogórze Dynowskie. Habitat preferences of Taraxacum zajacii were determined based on phytosociological relevés. It grows on wet loamy soils in mown but not undersown meadows of the order Molinietalia, mainly of the alliance Calthion. As a rule, it is accompanied by other dandelion species from the section Palustria: T. portentosum, T. vindobonense, T. polonicum and T. mendax. Representatives of these accompanying species were definitely less numerous. Probably T. zajacii performs better when competing with tall meadow plants.”

Zhang J.-W., Kilian N., Deng T., Souliya O. & Sun H. 2016: Melanoseris henryi (Asteraceae-Cichorieae) revisited: a new record of genus and species from the flora of Lao PDR with its systematic position. – J. Jap. Bot. 91(Suppl.): 112–119. Abstract: “Melanoseris henryi (Dunn) N. Kilian (Asteraceae-Cichorieae) is reported for the first time for the Bolaven Plateau of southern Laos (Champasak province). Hitherto this rare species was only known from the type collection made at Pu’er, in southern Yunnan, China, at the end of the 19th century, where it has not been recollected since. This is also the first record for the genus Melanoseris from Laos. The phylogenetic analysis based on DNA sequences of nuclear ribosomal internal transcribed spacer (nrITS) confirms the placement in the Flora of China of this species with 3–6-flowered capitula in the revived Melanoseris. Within theMelanoseris lineage, M. henryi clusters into a clade together with Melanoseris atropurpurea, M. likiangensis, and M. macrantha, all species with many-flowered capitula, which is sister to a clade of two species with 3-flowered capitula, M. tenuis and M. graciliflora. In our molecular phylogeny statistical support of the relationships within the Melanoseris lineage is, however, weak. A description and illustrations of Melanoseris henryi, which is also rare in southern Laos, are provided. The presence of Melanoseris in southern Laos provides new clues to illuminate the history of the geographical distribution and the evolution of this lineage, and even the relationships between the floras of southwestern China and southern Laos.” –––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 31 December 2016 Talavera S., Tremetsberger K., Ortiz M. de los Á., Ariza M. J. & Talavera M. 2016: Revisión del género Helminthotheca Vaill. (Cichorieae, Compositae). – Acta Bot. Malac. 41: 49–81. Abstract: “Revision of the genus Helminthotheca Vaill. (Cichorieae, Compositae). Based on a morphological study, we present the revision of the genus Helminthotheca Vaill., a small member of the subtribe Hypochaeridinae of the tribe Cichorieae, which is mainly distributed in the western part of the Mediterranean region. Helminthotheca is differentiated from the remaining genera of the subtribe by thepresence of ± spiny prickles and glochid-like bristles in stems, leaves and, sometimes, involucral bracts. The main distinguishing character, however, is the presence of 5 outer involucral leaves, which surround the proper involucre of the head. Based on the life cycle, the morphology of the outer involucral leaves and the fruit types found in the head, species of Helminthotheca are rearranged in three sections: Helminthotheca, Vigineixia y Eliptica. The sections Helminthotheca and Vigineixia, both monotypic, are annuals with cordate outer involucral leaves and dimorphic fruits in the head. The section Eliptica, with five recognized species, is differentiated from the other sections by its perennial habit, ovate or elliptic outer involucral leaves and homomorphic fruits in the head. Here, we make a new combination, Helminthotheca sect. Vigineixia (Pomel) Talavera, and give a new name to Picris subgen. Deckera sensu Battandier, Helminthotheca sect. Eliptica Talavera & Tremetsberger. The section Eliptica is the most complex section, due mainly to interspecific hybridization between all species, when they co-occur, with hybrid zones having been detected in the N of the Guadalquivir River in the W of the Sierra Morena (S Spain), in the westernmost part of the Rif Mountains, near the Tangier Peninsula, in the E Rif and Middle Atlas (NW Morocco), in the Algerian Atlas Mountains and in the argillaceous hills of Beni-Zenthis (Oran, Algeria).” –––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 31 December 2016 Talavera M., Berjano R., Jiménez F.

(Asteraceae) taxa collected from Turkey are presented and evaluated by cluster and principal coordinate analysis. Numerical analyses based on 26 anatomical traits showed that arrangement of tracheal elements in the root, presence of cortical bundles, latex canals, secretory cells and aerenchyma in the stem and mesophyll are valuable for groupingScorzonera taxa. Dendograms inferred from anatomical data were generally congruent with the traditional subgeneric classification of Scorzonera (Scorzonera L., Podospermum DC., Pseudopodospermum (Lipsch. et Krasch.) Lipsch.). However, the present study also show that the examined species may not be identified only based on the internal morphology of root, stem and leaf.

Current morphological and molecular results support treating T. reticulatus Boiss. & Huet and the two newly described taxa under the section Profundisulcati Kuthath. Molecular phylogentic reconstructions based on ITS data show that T. longirostris Sch. Bip. is a distinct species rather than a subspecies of T. porrifolius L.

Abstract: “Pollen quality was evaluated in Pilosella plants sourced from the field and representing various cytotypes (diploid to octoploid), reproduction modes (sexuality, facultative apomixis and seed sterility or semisterility) and status of origin (basic species, hybridogenous intermediate species and recent hybrids). Two methods of non-vital pollen staining were compared, providing a similar pattern of variation in pollen stainability and pollen size. A complex influence of ploidy level, reproduction mode and plant origin on pollen quality was found. Sexual biotypes had high and equable pollen stainability whereas apomictic and (semi)sterile plants were more variable in this trait. Nevertheless, the sexual, apomictic and (semi)sterile plants did not significantly differ in pollen stainability, while the impacts of both ploidy level and plant origin were significant. Apomictic triploids had low pollen stainability and heterogeneously sized pollen, most likely resulting from disturbed meiosis. The other biotypes, including higher odd-ploid cytotypes, displayed various patterns of pollen quality partially depending on the hybridogenous origin. Whereas high pollen quality was detected in most of the apomictic hexaploids and heptaploids, including recent hybrids, serious pollen dysfunction was found in most octoploids. Seed (semi)sterility was not strongly associated with reduced pollen quality. Either blocked or unstable pollen production was occasionally recorded, predominantly among recent hybrids. Despite autonomous apomixis independent of pollen, most apomictic biotypes displayed fairly high pollen stainability and pollen size homogeneity, implying sufficient production of viable reduced pollen. Most representatives of this agamic polyploid complex, including facultative apomicts, might efficiently mate as both male and female parents in natural populations.” –––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 5 December 2016 Zareh M.

Syst. Evol. 302: 971–984. Abstract: “Temperate grasslands belong to the most diverse plant communities of Central Europe. However, there is still a lack of information about glacial refugia and migration processes of herbaceous grassland and especially steppe species in Central Europe. Therefore, we analyzed the survival and postglacial immigration of Scorzonera purpurea to Central Europe. We investigated 348 individuals from 37 populations in Europe using amplified fragment length polymorphisms and chloroplast microsatellite analyses. Our study revealed two major genetic groups along the European distribution range consisting of western populations on the one hand and closely related central and (south)eastern populations on the other hand. Genetic variation was highest within populations from the Pannonian basin and decreased toward Western and Central Europe. Our study gives evidence for the long-term survival of S. purpurea in Western Europe and the postglacial immigration from the southeastern parts of Europe, maybe by domestic livestock of migrating farmers during the Neolithic age to Central Europe. Immigration presumably followed two routes from Pannonia along the river Danube into Southern Germany and from Pannonia along the northern border of the Carpathians to Northern Germany. In Central Germany, the different genetic lineages may have met and formed contact zones. Our data show that steppe species may both have survived in and immigrated to Western and Central Europe. Further and more detailed studies on other steppe species are, therefore, needed to investigate the origin of these rare and often endangered species more generally.” –––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 26 September 2016 Sears C.

Bot. 103: 1289–1299. Abstract: “PREMISE OF THE STUDY: Babcock and Stebbins coined the term agamic complex in their 1938 monograph of the North American Crepis agamic complex. Despite the historical role that this complex holds in the evolutionary literature, it has not been reexamined in over 75 years. We present a thorough reevaluation of the complex to test hypotheses proposed by Babcock and Stebbins about its origins and spread, the relationships of diploids, and the nature and origins of polyploids. METHODS: We used flow cytometry to infer ploidy of roughly 600 samples spanning the morphological and taxonomic diversity of the complex and a phylogenetic analysis of plastid DNA variation to infer maternal relationships among diploids and to infer maternal origins of polyploids. KEY RESULTS: We identified populations of all seven recognized diploids plus one new lineage. Phylogenetic analysis of plastid DNA variation in diploids revealed a well-resolved, but moderately supported phylogeny, with evidence for monophyly of the North America Crepis agamic complex and no evidence of widespread homoploid hybridization. Polyploids showed evidence of multiple origins and a pattern of frequent local co-occurrence consistent with repeated colonization of suitable sites. CONCLUSIONS: Our findings agree broadly with the distribution and variation of ploidy within and among species described by Babcock and Stebbins. One key difference is finding support for monophyly of North American species, and refuting their hypothesis of polyphyly. Our results provide an explicit phylogenetic framework for further study of this classic agamic complex.” –––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 19 September 2016 Ke R. & Chen Y.-S. 2016: A new species of Youngia (Asteraceae, tribe Cichorieae) from Yunnan, China. – Phytotaxa 275: 140–148.

The leaf shape in the Brazilian plants of the two species is less variable than in Asiatic or North American populations. This could possibly be a result of a single introduction to Brazil of each species. Both species are weeds, occurring in disturbed habitats in south and south-eastern Brazil. The two species are described, illustrated and their affinities are discussed. An identification key is provided to the six species of Lactuca (all introduced) in South America.” –––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 9 August 2016 Mateo Sanz G., Egido Mazuelas F. del & Gómiz García F. 2016: Aportaciones al conocimiento del género Hieracium laniferum L. en España, XXIII. – Fl.

Syst. Evol. 302: 367–384. Abstract: “The recently evolved genus Tolpis Adans. has its major center of diversity located in Macaronesia. Although recent advances have been made to understand the relationships of Tolpis species within Macaronesia, little is still known about the genetic patterns and genetic diversity of the Azorean and Madeiran Tolpis populations. To achieve this, a set of 8 microsatellite loci (SSR) was applied to 478 individuals of Tolpis azorica and T. succulenta. Genetic structure analysis, in addition to a spatial analysis, confirmed the existence of geographically circumscribed genetic patterns allied to a barrier effect by the sea in the Azorean T. azorica and T. succulenta. A detailed analysis of T. azorica revealed three different genetic groups, each group being particular to a different Azorean sub-archipelago, while the analysis conducted with T. succulenta confirmed the occurrence of a differential grouping between individuals from Azores and Madeira populations. The impact of catastrophic volcanic events and intense humanization of the habitats is discussed, in view of the present genetic diversity and structure of the species. In general, T. azorica populations showed high Fis values and some populations of T. succulenta both in Azores and in Madeira also showed signs of putative inbreeding. Conservation actions such as the eradication of invasive plant and animal species are advised but translocations of plants or diaspores between islands or between populations of a same island should not be attempted.” –––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 15 July 2016 Janas A., Musiał K., Kościńska-Pająk M. & Marciniuk P. 2016: Insights into developmental processes in anthers, ovaries, and ovules of Taraxacum belorussicum (Asteraceae-Cichorioideae) using DIC optics. – Pl. Syst. Evol. 302: 617–628. Abstract: “This study represents the first report on the embryological characteristics of triploid male-sterile dandelion Taraxacum belorussicum (section Palustria) from Poland. While this taxon is considered to be a male-sterile species, we found that the investigated individuals produced pollen. Irregular tetrads, triads and diads with microspores of unequal size were observed in the pollen loculi as a result of disturbed meiotic division, while anthers’ tapetum did not show structural disorders. Possible reasons for the plasticity in the expression of male sterility, as well as the role of pollen in apomicts, are discussed. Flowers of the examined individuals contained well-developed nectaries. The course of embryological processes in the ovules indicated an apomictic mode of reproduction in T. belorussicum. We observed meiotic diplospory of the Taraxacum type, in which first meiotic division starts but results in nuclear restitution, while undisturbed second meiotic division gives rise to a dyad of unreduced megaspores (diplodyad). After three mitotic divisions of the chalazal megaspore, a seven-celled unreduced female gametophyte developed. The features of ovule anatomy and characteristics of a mature female gametophyte corresponded to these described in sexually reproducing dandelions.” –––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 23 June 2016 Di Gristina E., Gottschlich G. & Raimondo F.

Abstract: “The pollen morphology of 45 taxa belonging to 15 sections of the genus Scorzonera distributed in Turkey were studied with light and electron microscopies. The pollen is generally 3-zonocolporate. Pollen grains are oblate-spheroidal with the polar axes 23.2–59.2 µm and the equatorial axes 27–62.5 µm. The outline is more or less circular to slightly elliptic in equatorial view and triangular or obtuse-hexagonal in polar view; amb semiangular to intersemiangular. Sculpturing is echinolophate. The spines are commonly concave-conical with a broad basis, sides are straight or slightly convex with a subacute tapered apical portion. Numerical analysis showed that polar axes, equatorial axes and exine thickness are valuable variables for seperating the examined taxa.” –––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 8 June 2016 Coşkunçelebı K., Makbul S. & Okur S. 2016: Studies on the achene morphology of Turkish species of Scorzonera L.

Abstract: “Macro- and micromorphological features of achenes belonging to 59 taxa from Turkey were observed via light and scanning electron microscopy. The findings agree with the traditional subdivision of Scorzonera into S. subg. Scorzonera, S. subg. Podospermum and S. subg. Pseudopodospermum. Members of S. subg. Podospermum were distinguished by achenes with a distinct carpopodium and horizontally striped epidermal cell surface; members of S. subg. Pseudopodospermum were distinguished by achenes with a conspicuous carpopodium and often ruminate and sometimes rugose-granulate or smooth epidermal surface, and members of Scorzonera s.str were distinguished by achenes without a carpopodium and with various combinations of surface patterns. The results also showed that the length, pubescence and surface pattern of achenes, as well as the carpopodium and anticlinal and periclinal walls of the epidermal cells are valuable for delimiting the examined species within the genus.” –––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 8 June 2016 Di Gristina E., Gottschlich G. & Raimondo F.

Abstract: “Critically endangered species representing ancient, evolutionarily isolated lineages must be given priority when allocating resources for conservation projects. Sound phylogenetic analyses and divergence time estimations are required to detect them, and studies on their population genetics, ecological requirements and breeding system are needed to understand their evolutionary history and to design efficient conservation strategies. Here we present the paradigmatic case of Avellara, a critically endangered monotypic genus of Compositae inhabiting a few swamps in the west–southwest Iberian coastal plains. Our phylogenetic and dating analyses based on nuclear (ITS) and plastid (matK) DNA sequences support a Miocene (>8.6 Ma) divergence between Avellara and closely related genera, resulting in marked morphological and ecological differentiation. We found alarmingly low levels of genetic diversity, based on AFLPs and plastid DNA sequences, and confirmed the prevalence of clonal reproduction. Species distribution modelling suggested a large macroclimatically suitable area for Avellara in the western Iberian Peninsula, but its apparently narrow microecological requirements restrict its distribution to peatlands with low-mineralised waters. Although five populations have been recorded from Spain and Portugal in the past, its current distribution may be reduced to only one population, recurrently found in the last decade but threatened by herbivory and habitat degradation. All this confirms the consideration of Avellara as a threatened species with high phylogenetic singularity, and makes it a flagship species for plant conservation in both Spain and Portugal that should be given priority in the design of in situ and ex situ conservation programmes.” ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 18 March 2016 Mateo Sanz G. 2016: Novedades sobre el género Pilosella Hill.

Abstract: “Hypochaeris leontodontoides is a rupicolous species endemic to the Atlas Mountains (Morocco), where it occurs in scattered populations. This study aims to understand the biogeographic structure of a high mountain species in a rather small area of NW Africa. We used Amplified Fragment Length Polymorphism (AFLP) to investigate the population structure and phylogeography of H. leontodontoides in 19 populations sampled from the entire species distribution range. Multivariate analyses including PCoA, UPGMA analysis, and Bayesian clustering were applied to infer the influence of past biogeographic events. The AFLP differentiation among the populations was high (F ST = 0.508). A significant geographical pattern by mountain region was found. The different phylogeographical analyses revealed four main groups corresponding to four well-defined geographic regions: Middle Atlas, Eastern High Atlas, Central High Atlas, and Western High Atlas, and highlighted the Western High Atlas as the most divergent group. Our data also indicate two regions as refuges during the Pleistocene ice ages: the Middle Atlas and the northernmost area of the Western High Atlas.” ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 23 February 2016 Armağan M. 2016: Gundelia vitekii a new species from Turkey. – Ann.
