Z., Fernández I. Á., Jardim R. & Menezes de Sequeira M. 2014: Andryala perezii (Asteraceae), a new species from the Canary Islands. – Novon 23: 147-156. Abstract: Andryala perezii M. Z. Ferreira, R. Jardim, Alv. Fern. & M. Seq. (Asteraceae), a new species from the Canary Islands, is described and illustrated. Although formerly included in A. glandulosa Lam., the new species differs remarkably from Madeiran populations by its woolly stellate pubescence, scattered glandular pubescence restricted to the peduncles and involucral bracts, peduncles flattened and enlarged at the base of the capitula, and smaller cypselae. Andryala perezii has a habit similar to that of the Canarian A. pinnatifida Aiton but may be identified by its densely stellate pubescence on the stems; grayish white or glaucous, congested leaves with dense stellate pubescence on both surfaces and undulate-crispate margins; longer peduncles; and smaller cypselae with a ring of short teeth at the apex equivalent to the height of the prolongation of the ribs. Comments on the chromosome numbers, geographic distribution, habitat, and conservation status are also presented. The name A. pinnatifida Aiton f. cuneifolia Sch. Bip. is lectotypified and is transferred in rank as A. pinnatifida subsp. cuneifolia (Sch. Bip.) M. Z. Ferreira, R. Jardim, Alv. Fern. & M.

G. 2014: A reference genetic linkage map of apomictic Hieracium species based on expressed markers derived from developing ovule transcripts. – Ann. Bot. 115: 567–580.

Abstract: Background and Aims Apomixis in plants generates clonal progeny with a maternal genotype through asexual seed formation. Hieracium subgenus Pilosella (Asteraceae) contains polyploid, highly heterozygous apomictic and sexual species. Within apomictic Hieracium, dominant genetic loci independently regulate the qualitative developmental components of apomixis. In H. praealtum, LOSS OF APOMEIOSIS (LOA) enables formation of embryo sacs without meiosis and LOSS OF PARTHENOGENESIS (LOP) enables fertilization-independent seed formation. A locus required for fertilization-independent endosperm formation (AutE) has been identified in H. piloselloides. Additional quantitative loci appear to influence the penetrance of the qualitative loci, although the controlling genes remain unknown. This study aimed to develop the first genetic linkage maps for sexual and apomictic Hieracium species using simple sequence repeat (SSR) markers derived from expressed transcripts within the developing ovaries.

Methods RNA from microdissected Hieracium ovule cell types and ovaries was sequenced and SSRs were identified. Two different F1 mapping populations were created to overcome difficulties associated with genome complexity and asexual reproduction. SSR markers were analysed within each mapping population to generate draft linkage maps for apomictic and sexual Hieracium species.

Key Results A collection of 14?684 Hieracium expressed SSR markers were developed and linkage maps were constructed for Hieracium species using a subset of the SSR markers. Both the LOA and LOP loci were successfully assigned to linkage groups; however, AutE could not be mapped using the current populations. Comparisons with lettuce (Lactuca sativa) revealed partial macrosynteny between the two Asteraceae species.

Conclusions A collection of SSR markers and draft linkage maps were developed for two apomictic and one sexual Hieracium species. These maps will support cloning of controlling genes at LOA and LOP loci in Hieracium and should also assist with identification of quantitative loci that affect the expressivity of apomixis. Future work will focus on mapping AutE using alternative populations.

Syst. Evol. 301: 279–290. Abstract: We studied the significance of sexual reproduction as a source of ploidy level variation in a model system consisting of hexaploid, facultatively apomictic Pilosella bauhini and tetraploid, sexual P. officinarum. As the maternal parent, apomictic P. bauhini generated higher ploidy level variation than sexual P. officinarum. Ploidy levels of its progeny ranged from triploid to octoploid under experimental conditions and even to decaploid in the field. This progeny diversity resulted from the breeding system in P. bauhini, which included haploid parthenogenesis and sexual reproduction through both reduced and unreduced gametes besides prevailing apomixis; these particular reproductive pathways have been quantified. Sexual P. officinarum, on the other hand, reproduced exclusively through fusion of reduced gametes and produced only pentaploid hybrids or tetraploid progeny from autogamy, allogamy or both. Surprisingly, sexual P. officinarum was also the species showing stronger reproductive isolation, especially under the field conditions where intra-specific fertilization was highly favoured, most probably through competition between conspecific and heterospecific pollen. Apomictic P. bauhini thus appeared to be a significant source of ploidy level variation in the model population even though most of its progeny was formed clonally through apomixis. Only part of this variation was manifested in the field. ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 29 January 2015 Reisch C., Windmaißer T., Vogler F., Schuhwerk F. & Meyer N. 2014 [2015]: Genetic structure of the rare and endangered Hieracium wiesbaurianum group (Asteraceae) in Bavaria. – Bot. J. Linn. Soc. 177: 112–123. Abstract: The rare and endangered Hieracium wiesbaurianum species group shows a scattered relictual distribution in Bavaria. Recently, a couple of populations were discovered which clearly differ from all other populations. If these must be considered as taxonomically independent units, they would be of crucial conservation interest, because of the sole responsibility that Bavaria has for these worldwide endemics. We therefore analysed the genetic structure of H. wiesbaurianum in a comparative approach. Our analysis comprised 37 populations of 13 taxa of H. wiesbaurianum, H. bifidum and H. laevigatum, including three potentially new taxa. We applied amplified fragment length polymorphism (AFLP) analysis and observed only limited genetic variation within populations and taxa. Nevertheless, each studied individual exhibited a unique genotype. An analysis of molecular variance revealed high levels of genetic variation between taxa, but populations were genetically less different. The clear genetic differentiation between the studied taxa was supported by neighbor-joining cluster analyses and principal coordinate analyses in which every individual was clearly assigned to its respective taxon. The three potentially new taxa were genetically as well differentiated as the other taxa included in our study. This supports the assumption that they should be treated as taxonomically independent units of high conservation interest. Therefore, the genetic analysis confirmed the morphologically based classification of the studied Hieracium taxa. ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 29 January 2015 Rich T.

Abstract: A new species Ixeridium calcicola (Compositae) endemic to middle altitude (ca 1,000–2,000 m asl) limestone mountains of eastcentral Taiwan is described based on morphological and chromosome cytological observations and molecular phylogenetic analyses. Ixeridium calcicola resembles Ixeridium transnokoense, endemic to upper montane and alpine ranges (2,600–3,500 m asl) of Taiwan, in the dwarf habit, but differs in the oblong to lanceolate leaf blades (vs. linear to linear-lanceolate), the presence of mucronulate teeth on the leaf margin and petiole (vs. smooth to very sparse), the dark purple lower leaf surface (vs. greenish), the capitulum with 10 to 12 florets (vs. 5 to 7) and 8 to 10 inner phyllaries (vs. 5, rarely to 7). The basic chromosome number in Ixeridium was known as X = 7. However, the new species has a basic chromosome number of X = 8, as recorded also in the closely related Ixeris. Molecular phylogenetic analyses with the expanded sampling of Ixeridium and Ixeris including both type species supported the monophyly of each of the genera and the placement of the new species in Ixeridium. The result of the phylogenetic analyses and detailed observation of the chromosome morphology revealed that X = 8 in Ixeridium calcicola is derived from centric fission in an ancestral karyomorphotype with X = 7 in Ixeridium. Ixeridium calcicola and Ixeridium transnokoense formed a Taiwan endemic lineage and their estimated divergence time was in the middle Pleistocene. Their common ancestral lineage may have experienced altitudinal distribution shifts in response to glacial-interglacial temperature fluctuation, and a lineage which had not retreated to alpine ranges in an interglacial period likely survived in a limestone refugium, where ordinary plant species did not grow, leading to allopatric speciation. ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 21 November 2014 Talavera M., Fernández-Piedra M.

Syst. Evol. 300: 2091-2104. Abstract: We used allozymes to elucidate the genetic variation of Pilosella echioides and P. rothiana in the Pannonian Basin and its relationship with morphology and modes of reproduction. The former species consists of sexual diploid, apomictic tetraploid, and very rare sexual tetraploid populations; the latter is exclusively tetraploid and apomictic. As expected, we detected the highest intra-population variation in diploid populations of P. echioides. Nonetheless, 73 % of populations of tetraploid P. echioides and 64 % of P. rothiana consisted of 2–7 multilocus allozyme genotypes, the means being 5.75 in P. echioides and 2.64 in P. rothiana. Both the proportion of distinguishable genotypes (G/N) per population and genotype diversity (D) per population significantly differed between diploid P. echioides (means 0.415 and 0.828, respectively) on the one hand and tetraploid P. echioides (means 0.252 and 0.387, respectively) and P. rothiana (means 0.213 and 0.347, respectively) on the other. Rather surprisingly, we found an excess of homozygotes (positive F IS) in diploids, which indicates inbreeding. Tetraploids of P. echioides have most likely originated from only a few polyploidization events and have spread thanks to agamospermy—at least populations from the NW part of the area under study seem to be monophyletic. Genetic differences within the putatively hybridogeneous species P. rothiana are small. It seems plausible that it has a common origin and that it spreads independently of its parents (P. echioides and P. officinarum). A certain level of genetic diversity can be caused by residual sexuality or less likely by repeated polytopic hybridization between P. echioides and P. officinarum. Pilosella sterrochaetia is reported here from Hungary for the first time. It is an extremely rare primary diploid hybrid between diploid P. echioides and P. leucopsilon. Its intermediate nuclear genome size also confirms its hybrid origin. ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 17 October 2014 Steinbach P. 2014: Zur Anzahl und Keimung der Diasporen des Lämmersalats (Arnoseris minima). – Bot.

Abstract: We investigated genetic variation and evolutionary history of closely related taxa of Picris subsect. Hieracioides with major focus on the widely distributed P. hieracioides and its closely related congeners, P. hispidissima, P. japonica, P. olympica, and P. nuristanica. Accessions from 140 sample sites of the investigated Picris taxa were analyzed on the infra- and the inter-specific level using nuclear (ITS1-5.8S-ITS2 region) and chloroplast (rpl32-trnL(UAG) region) DNA sequences. Genetic patterns of P. hieracioides, P. hispidissima, and P. olympica were shown to be incongruent and, in several cases, both plastid and nuclear alleles transcended borders of the taxa and genetic lineages. The widespread P. hieracioides was genetically highly variable and non-monophyletic across both markers, with allele groups having particular geographic distributions. Generally, all gene trees and networks displayed only a limited and statistically rather unsupported resolution among ingroup taxa causing their phylogenetic relationships to remain rather unresolved. More light on these intricate evolutionary relationships was cast by the Bayesian coalescent-based analysis, although some relationships were still left unresolved. A combination of suite of phylogenetic analyses revealed the ingroup taxa to represent a complex of genetically closely related and morphologically similar entities that have undergone a highly dynamic and recent evolution. This has been especially affected by the extensive and recurrent gene flow among and within the studied taxa and/or by the maintenance of ancestral variation. Paucity of phylogenetically informative signal further hampers the reconstruction of relationships on the infra- as well as on the inter-specific level. In the present study, we have demonstrated that a combination of various phylogenetic analyses of datasets with extremely complex and incongruent phylogenetic signal may shed more light on the interrelationships and evolutionary history of analysed species groups. ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 8 September 2014 Kirschner J., Záveská Drábková L., Štěpánek J. & Uhlemann I. 2014: Towards a better understanding of the Taraxacum evolution (Compositae–Cichorieae) on the basis of nrDNA of sexually reproducing species. – Pl. Syst. Evol. http://dx.doi.org/10.1007%2Fs00606-014-1139-0 Abstract: The genus Taraxacum is characterized by prevailing complex multiple hybridity, frequent polyploidy and widespread agamospermous reproduction, which makes the phylogenetic analysis difficult. On the basis of the previous analysis of the variation of nrDNA in Taraxacum taxa with different ploidy levels and modes of reproduction, to mitigate consequences of the reticulate complexity of the genus, a phylogenetic study of 52 samples of sexually reproducing dandelions of 26 sections (and another 13 agamospermous representatives of other sections known to include sexuals) was carried out. Both sexual and agamospermous samples were analysed using maximum parsimony and neighbour network. Exclusively sexual dandelions were analysed using the same approaches. In spite of the general agreement among various types of analyses, there is a limited overall congruence between results of nrDNA analyses and the established taxonomic system of the genus Taraxacum. The analyses shed light on the relationships among the most primitive groups. A stable clade is formed by representatives of the sections Primigenia, Orientalia, Sonchidium, Piesis and T. cylleneum. Another case of stable relationships is that of the members of the sect. Dioszegia. Relationships between the sects. Erythrosperma and Erythrocarpa were supported, and the relatedness of the members of sect. Australasica was confirmed. Rather unexpectedly, the agamospermous samples of the sect. Oligantha (T. minutilobum) are shown to be closely related with the sect. Macrocornuta. The latter section is generally considered to be close to sect. Ceratoidea (T. koksaghyz) on morphological grounds but this presumption is not corroborated by the results of nrDNA analyses. Analyses of 72 samples of sexual dandelions were also performed using the trnL–trnF region of the chloroplast DNA. The maximum parsimony analysis of this region reveals intraspecific variation in a number of ancestral diploid sexual species, all present in the two main branches of the cladogram. This phenomenon is attributed to the ancient gene flow and possibly to the persistence of ancestral cpDNA polymorphism. The strict consensus cpDNA tree information content and interpretability is quite low. The maximum parsimony analysis of combined nrDNA and cpDNA data sets was also performed with expectably low interpretability of the results. ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 5 September 2014 Ogawa M. 2014: [Taraxacum kiushianum H.

J. 2014: Jestřábník hroznatý (Hieracium racemosum) v České republice. Hieracium racemosum in the Czech Republic. – Zprávy Čes. Bot. Společ., Praha 49: 1–27. Abstract: The distribution of Hieracium racemosum in the Czech Republic was studied based on herbarium specimens deposited in 22 public herbaria. This species, classified within H. sect. Italica, is one of 58 native hawkweeds (Hieracium s. str.) of the Czech flora. From H. sabaudum, the most similar species, it may be distinguished by sually shortly petiolate lower stem leaves, racemous to paniculate synflorescence, rather long inner involucral bracts, which are dark to pale green and have a light green margin, as well as by yellowish or grey, rarely ed to chestnut-brown achenes and usually dentate (non-fimbriate) receptacle pits. The leaf arrangement, i.e. he concentration of leaves in the middle or lower third of the stem, frequently used as the main character to distinguish H. racemosum from H. sabaudum, has only limited diagnostic value. Traditionally, six subspecies are reported from the Czech Republic, with most Czech populations of H. racemosum assigned to H. racemosum subsp. barbatum and subsp. racemosum. Using flow cytometry measurements and chromosome counts, three plants originating from two populations from the south-eastern parts of Czechia were assessed to be triploid (2n - 3x) and one plant had a chromosome number of 2n = 27, respectively. We revised 541 herbarium specimens of this species collected in the country, of which 432 (i.e. about 84 %) were originally identified correctly (including taxonomic synonyms). However, another 400 specimens originally identified as H. racemosum were revised as H. sabaudum (97 %) or H. umbellatum (3 %). In the Czech Republic, most localities of H. racemosum are concentrated in Moravia (eastern part of the country). Isolated locations are found in eastern Bohemia and single ourposts further towards the west. Based on the number of specimens revised, the distribution map presented here may be considered representative. The infraspecific taxonomy of H. racemosum and possible occurrence of H. neoplatyphyllum in the Czech Republic require further research. ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 4 August 2014 Gottschlich G. & Huber A. 2014: Hieracium polymastix, ein Neufund und Hieracium glomeratum, ein Wiederfund für die Schweiz. – Bauhinia 25: 51–57.

Abstract: We studied a small, spatially limited population of Pilosella plants, rich in morphological types, in the southwestern part of central Bohemia, Czech Republic. The following tetraploid parental Pilosella species putatively gave rise to the hybrid swarm analysed: sexual P. officinarum and apomictic P. polymastix (P. bauhiniP. caespitosa). In addition, the swarm consisted of (i) a stabilized tetraploid apomictic P. melinomelas (P. officinarum<P. polymastix) represented by two isozyme phenotypes (one dominating), and (ii) tetraploid and sexual hybrids between P. officinarum≥P. polymastix, with 16 isozyme phenotypes in the 18 plants analysed. We also found pentaploid P. bauhini (three plants comprising one isozyme phenotype), one hexaploid plant corresponding to P. melinomelas (putative 2n + n hybrid) and one pentaploid plant (probably a hybrid between hexaploid and unknown tetraploid). The single triploid plant detected in the hybrid swarm is probably of polyhaploid origin. Both P. polymastix and P. melinomelas are rare hybrid species, which because they had not been recorded for many years were considered as probably extinct in the Czech Republic. ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 20 June 2014 Bean A.

The new species can be easily distinguished by morphology from the only species known to possess 5 florets, Y. szechuanica. The infrageneric classification and the recently debated circumscription of Youngia are discussed in the light of the nrITS phylogeny, which includes several species for the first time. Pseudoyoungia is confirmed as a congener of Youngia.

Abstract: Faberia is a perennial herbaceous member of Asteraceae that is mainly distributed in central and southwestern China. Nuclear (ITS) and plastid (psbA–trnH, rbcL, matK, and trnL–F) sequences representing five Faberia species were analyzed with maximum parsimony, maximum likelihood, and Bayesian inference, all of which strongly supported the monophyly of Faberia. Faberia nanchuanensis, F. cavaleriei, and F. faberi from central China form a well-supported clade. Additionally, F. sinensis and F. thibetica from southwestern China also form a well-supported clade. Incongruence between nuclear and plastid fragments was interpreted as hybridization or limited character evolution in the plastid DNA. Faberia may have descended from hybridization between Lactucinae and Crepidinae. Besides phylogenetic results, Faberia nanchuanensis is recorded for the first time from Hunan Province, and F. sinensis from the Tibet Autonomous Region. ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 21 May 2014 Liu Y. & Yang Q.-E. 2014: Cytotaxonomy of Dubyaea glaucescens (Compositae–Cichorieae). – Nordic J. Bot. xxx Abstract: Recent molecular phylogenetic analyses indicate that Dubyaea glaucescens (Compositae–Cichorieae) should be transferred to the genus Faberia as F. glaucescens. Here, we present cytological evidence for this transfer. Dubyaea glaucescens comprises two ploidy levels, 2n = 34 (diploid) and 2n = 51 (triploid), making the basic chromosome number x = 17. The chromosomes vary in length from 5.82 μm to 2.11 μm, and the karyotypes are 2n = 20m + 14sm (3sat) for the diploid cytotype and 2n = 30m + 21sm (3sat) for the triploid cytotype. Karyological characters of D. glaucescens, including chromosome number, size, morphology, and karyotype asymmetry, all agree remarkably with those reported previously in Faberia, but are distinct from those in other species of Dubyaea. The transfer of D. glaucescens to Faberia is thus strongly corroborated.  ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 8 May 2014 Tyler T. 2014: Critical notes on species of Hieracium (Asteraceae) reported as common to Sweden and Britain. – New J. Bot. 4: 25–32. Abstract: All species of Hieracium sectt. Hieracium, Vulgata (incl. Bifida) and Oreadea originally described from the Nordic countries, but reported in recent accounts as occuring in the British Isles, have been scrutinised based on specimens and published descriptions. Out of 29 species stated as occurring in Britain and native to Fennoscandia, only four are confirmed (H. caesiomurorum, H. oistophyllum, H. pellucidum and H. triviale). These are all species with wide distributions in Fennoscandia and northern Europe and their occurence in Britain is thus not surprising. In addition, the first British occurrence of the widespread European species H. neopinnatifidum is reported. Apart from the above four, H. caesitium, H. diaphanoides and H. austrinum (H. scanicum) are possibly also native to both areas, although the material examined is not fully conclusive. In addition, at least a few species occur as aliens in both Sweden and Britain, but a further twelve need to be critically compared. Most of the Nordic names used for British plants are found to be based on misidentifications and the species concerned will have to be described and named anew. It is concluded that it is not good practice to borrow names of Hieracium species from distant areas without critically comparing types, authentic specimens and relevant literature. Only a very few species of this genus have distributions that stretch into several countries or across major water bodies.  ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 7 May 2014 Sailer C., Schmid B., Stöcklin J. & Grossniklaus U. 2014: Sexual Hieracium pilosella plants are better inter-specific, while apomictic plants are better intra-specific competitors. – Perspect. Pl Ecol. Evol. Syst. 16: 43–51. Abstract: Apomixis, asexual reproduction through seeds, occurs in over 40 plant families. This widespread phenomenon can lead to the fixation of successful genotypes, resulting in a fitness advantage. On the other hand, apomicts are expected to lose their fitness advantage if the environment changes because of their limited evolutionary potential, which is due to low genetic variability and the potential accumulation of deleterious somatic mutations. Nonetheless, some apomicts have been extremely successful, for example certain apomictic accessions of Hieracium pilosella L. from New Zealand, where the plant is invasive. Here, we investigate whether the success of these apomictic accessions could be due to a fitness advantage by comparing the vegetative competitiveness of apomictic H. pilosella from New Zealand with sexual accessions of H. pilosella from Europe. Sexual and apomictic plants were grown either (A) alone (no competition), (B) in competition with the other type (intra-specific competition), (C) in competition with the grass Bromus erectus (inter-specific competition), and (D) in competition with the other type and the grass B. erectus (intra- and inter-specific competition). To distinguish effects of apomixis and the region of origin, different H. pilosella lineages were compared. Furthermore, experiments were carried out to investigate effects of the ploidy level. We show that sexual plants are better inter-specific competitors than apomicts in terms of vegetative reproduction (number of stolons) and vegetative spread (stolon length), while apomicts do better than sexuals in intra-specific competition. The magnitude of the effect was in some cases dependent on the ploidy levels of the plants. Furthermore, apomicts always produced more stolons than sexuals, suggesting potential displacement of sexuals by apomicts where they co-occur. ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 10 April 2014 Křístková E., Lebeda A., Novotná A., Doležalová I. & Berka T. 2014: Morphological variation of Lactuca serriola L. achenes as a function of their geographic origin. – Acta Bot.

Abstract: The morphological characteristics of achenes of Lactuca serriola represented by 34 local populations from Slovenia and 12 local populations from Sweden were studied in relation to their eco-geographical conditions. In total, eight quantitative morphological characters were evaluated: length and width of achene body; index length/width of achene body; number of ribs on achene body; length of beak; length of pappus bristles; pappus area and discus diameter. NestedANOVAanalysis indicated significant differences in length and width of achene body, length of pappus bristles, and pappus area between Slovenian and Swedish populations.Achenes from Slovenia were longer, wider and possessed longer pappus bristles than achenes from Sweden. Among geographical factors, latitude had the greatest impact on the morphological characters evaluated. Significant differences in seven parameters were also found between populations within countries and between samples within populations. It is probable that this variation has a genetic basis with sufficient variation within populations to permit continued selection. ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 20 March 2014 Štěpánek J. & Kirschner J. 2014: A revision of names in Taraxacum sect.
