Two new species of eriophyoid mites were discovered in Hungary, viz. Aculodes caespiticolus sp. nov. collected from Sesleria sadleriana Janka (Poaceae) and Aceria cumaniamajoris sp. nov. found on Polygonum aviculare L. (Polygonaceae). Detailed morphological description of female, male and nymph is given. A key to Aculodes spp. already known from Hungary is given.

Several names belonging to the Sesleria sect. Argenteae (Poaceae) were discussed in this paper and, where necessary, typified. Lectotypes were designated for the names Sesleria nitida var. brevidentata, S. nitida var. intermedia, S. nitida var. tenoreana f. macrostachya, and S. nitida var. tenoreana f. visianii. Neotypes were designated for the names Sesleria nitida var. tenoreana s.s. and S. nitida var. de-gasperiana. Synonyms were proposed for the following names (accepted names in brackets): S. feretrana (= S. italica), S. italica subsp. mariculensis (= S. italica), S. nitida var. brevidentata (= S. vaginalis), S. nitida var. candae (= S. italica), S. nitida var. intermedia (= S. robusta), S. nitida var. tenoreana f. visianii (= S. italica), and S. nitida var. tenoreana f. macrostachya (= S. italica). As regards Sesleria nitida var. de-gasperiana and S. nitida var. sancti-marinii, they were confirmed as synonyms of S. pichiana. Due to the extremely limited number of herbarium specimens available, we could not confirm the taxonomic autonomy of S. nitida var. pulchella (basionym of the taxon currently accepted as S. pulchella) and consider it as a preliminary synonym of Sesleria italica.

This paper presents the results of a detailed study of leaf blade anatomical traits of populations of the Sesleria juncifolia complex from the Balkan Peninsula. The measurements were performed on cross sections of 302 tiller leaf blades from 24 populations. We calculated basic descriptive statistics for each character state. Principal component and canonical discriminant analyses were used to identify the structure of variability and the characters that majorly contributed to the differentiation of the defined groups. Cluster analysis was done to estimate the distances among the studied populations. We provide a detailed description of the leaf blade anatomy of the different populations of S. juncifolia complex investigated within Croatia, Bosnia and Herzegovina, Montenegro, Serbia and North Macedonia. The results show that most of the characters exhibit moderate degrees of variation. The principal component analysis shows slight separation of populations from northwestern Croatia. Canonical discriminant analysis shows that the three a priori defined groups—three species, S. interrupta, S. juncifolia and S. ujhelyii, can be distinguished based on leaf blade anatomical characters. In addition to the characters that were singled out as statistically most significant for differentiation of the three species in discriminant function analysis, the most useful characters for their delimitation are the length of the trichomes on the adaxial side of the leaf, as well as qualitative characters such as the sclerenchyma on the abaxial side of the leaf (continuous or interrupted) and the type of indumentum of the adaxial side of the leaf (very hairy, hairs long vs. very weakly hairy, hairs short). The northwestern populations of S. juncifolia mostly have glabrous leaves or single hairs on the adaxial side of the leaf, while in S. interrupta and S. ujhelyii populations, individuals always have hairy leaves. The presence of continuous subepidermal sclerenchyma has proven to be a good differential character for separating S. ujhelyii from the S. juncifolia and S. interrupta.

In this contribution, new chromosome data regarding two taxonomically critical genera of the Italian flora, namely Plantago and Sesleria, are presented. All the specimens analysed in this paper were collected in the Italian territory and include three chromosome counts for Plantago (P. albicans, P. crassifolia, and P. subulata) and two counts for Sesleria (S. caerulea and S. nitida).

Polyploidization has played an important role in the diversification of the genus Sesleria (Poaceae), which comprises c. 48 species and subspecies mostly distributed in Europe. The genus' centre of diversity clearly is the Balkan Peninsula, harbouring about 80% of the species, half of which are endemic to this area. We employed chromosome counts, measurements of absolute genome size and determination of relative DNA-content for 460 populations belonging to 43 species of Sesleria. Our main aim was to provide essential baseline data for future molecular genetic reconstructions of the genus' evolutionary history. Relative genome size allowed for a mostly clear separation of four ploidy levels. The most frequent and widespread cytotypes are tetraploids followed by octoploids, while di- and dodecaploids were only found in a few species. We present first chromosome numbers for the tetraploid species S. doerfleri, S. phleoides, S. skipetarum and S. tuzsonii as well as for diploid S. ovata. Based on relative and partly also on absolute genome size measurements, ploidy level was determined in tetraploid S. rhodopaea and S. voronovii for the first time, and new cytotypes were identified in S. interrupta, S. kalnikensis and S. wettsteinii (tetraploids), S. caerulea, S. klasterskyi, S. latifolia, S. tenerrima, S. ujhelyii and S. vaginalis (octoploids), and S. albanica and S. vaginalis (dodecaploids). While most Sesleria species are ploidy-uniform, several comprise two or even, in the case of S. vaginalis, three ploidy levels. Genome downsizing after polyploidization was confirmed by significant negative correlation between ploidy level and monoploid genome size. Finally, we found a significant increase in monoploid relative genome size towards the margin of the genus' distribution area, which may be triggered by increased activity of transposable element in populations exposed to environmental or genomic stress. © 2015 The Linnean Society of London, Botanical Journal of the Linnean Society, 2015, 179, 126–143.

The species-rich grass genus Sesleria is one of the most intricate genera of the European flora. Almost all species of the genus Sesleria are polyploid; only two species from the Alps, previously segregated as separate genera Psilathera and Sesleriella, are diploid. In addition, there is controversy about two diploid counts of S. comosa from the Bulgarian Rila and Pirin mountain ranges. These are the single reports of diploidy in Sesleria s. str., which would have significant impact on the future phylogenetic reconstruction of the genus’ evolutionary history. In order to confirm or reject these reports, we determined the relative DNA-content for 67 individuals of S. comosa from the two Bulgarian localities, from which diploid cytotypes have been reported. All analyzed individuals were clearly separated into two ploidy levels: DNA-tetraploids and DNA-octoploids. These results are in accordance with our previous comprehensive study on genome sizes in the genus, but are in stark contrast to the previous reports. Therefore, we suggest that the diploid counts rather refer to co-occurring, morphologically somewhat similar diploid Alopecurus gerardii, which has probably overgrown and outcompeted the slower growing and more susceptible S. comosa during cultivation before root tips were fixed for chromosome counting.

Global climate change may act as a potent agent of natural selection within species with Mediterranean mountain ecosystems being particularly vulnerable. The aim of this research was to analyze whether the phenotypic plasticity of Sesleria nitida Ten. could be indicative of its future adaptive capability to global warming. Morphological, anatomical, and physiological leaf traits of two populations of S. nitida growing at different altitudes on Mount Terminillo (Italy) were analyzed. The results showed that leaf mass per unit leaf area, leaf tissue density, and total leaf thickness were 19, 3, and 31% higher in leaves from the population growing at 1,895 m a.s.l. (B site) than in leaves from the population growing at 1,100 m a.s.l. (A site), respectively. Net photosynthetic rate (PN) and respiration rate (RD) peaked in June in both A and B leaves [9.4 ± 1.3 μmol(CO2) m−2 s−1 and 2.9 ± 0.9 μmol(CO2) m−2 s−1, respectively] when mean air temperature was 16 ± 2°C. RD/PN was higher in B than in A leaves (0.35 ± 0.07 and 0.21 ± 0.03, respectively, mean of the study period). The mean plasticity index (PI = 0.24, mean of morphological, anatomical, and physiological leaf traits) reflected S. nitida adaptability to the environmental stress conditions at different altitudes on Mount Terminillo. Moreover, the leaf key traits of the two populations can be used to monitor wild populations over a long term in response to global change.

Phytosociological and numerical analyses of grasslands dominated by Sesleria juncifolia s.l. in Serbia were performed in order to resolve their syntaxonomy and nomenclature. Twelve releves were sampled on Mt. Mučanj (western Serbia), which were then compared with similar releves from other parts of the Balkan Peninsula by means of numerical analyses. The releves were classified using cluster analysis, while the ordination was conducted using Detrended Correspondence Analysis (DCA). The results suggest the occurrence of two floristically well defined Dinaric associations in Serbia: Seslerio juncifoliae-Edraianthetum graminifolii ass. nova from Mt. Mokra Gora (Oxytropidion urumovii, Elyno-Seslerietea) and Diantho petraeae-Seslerietum juncifoliae ass. nova (Chrysopogono-Saturejion, Festuco-Brometea) from Mt. Mučanj.

Reconstruction of relationships among populations of the morphologically polymorphic and taxonomically intricate Sesleria rigida sensu Fl. Eur. based on Amplified Fragment Length Polymorphisms (AFLPs) revealed four clearly differentiated genetic groups that did only partly follow recent taxonomic concepts, but were strictly allopatric. While some of the previ- ously described taxa constitute distinct genetic entities, others have no taxonomic value. Synthesizing our AFLP data with ploidy-level information obtained from all genetically investigated individuals as well as with chromosome counts revealed that tetraploid individuals prevail, while octoploids occur only within S. filifolia. Lack of AFLP divergence between tetra- and octoploids suggests an autopolyploid origin of the latter. The genetic differentiation pattern was reflected by morphological differentiation, allowing for a taxonomic revision of the constituents of S. rigida sensu Fl. Eur. resulting in recognition of the four species S. achtarovii, S. filifolia, S. rigida, and S. serbica.

Seslerio uliginosae-Scorzoneretum purpureae is the only xerothermic community of the Festuco-Brometea class, where a rare species known as Sesleria uliginosa occurs in Poland. A couple of sites hosting this association in the Nida Basin were described in the 1920s and 1950s. All these stands are now situated in the areas designated as xerothermic nature reserves. The study aimed at describing the present-day characteristics of this rare association, the most likely being endemic in Poland, as well as the changes that have occurred in it. The species diversity and the contribution of xerothermic plants have decreased significantly in terms of their number and cover coefficient. Some of the diagnostic species of the association have become extremely rare. Sesleria uliginosa is the only one without visible changes in their dominant position in the community. Mosses, that have played a significant role before, were among the vanished species. At the same time, an increase in number and cover of mesophilous meadows species was observed. Mesophilous grasses belong to the group of species growing in significance in the phytocoenoses. The observed changes in species composition were reflected in a statistically significant increase of nitrogen indicator value. The slow process of succession observed in the Seslerio-Scorzoneretum purpureae could be attributed to the lack of appropriate land use, e.g. mowing and grazing that have been ceased in the nature reserves.

This paper presents the results of a multivariate morphometric study of leaf anatomical characters in different populations of Sesleria rigida sensu lato in Serbia. Morphometric analyses were performed on cross-sections of 521 tiller leaves collected from 21 populations of S. rigida. Principal component analysis and canonical discriminant analysis were used to identify the structure of variability and to determine which variables discriminate between the groups. The UPGMA (unweighted pair-group average linkage) clustering analyses based on leaf anatomical characters and habitat climatic characteristics were employed to explore whether the observed anatomical differences are a result of adaptive responses. Regression analysis (linear regression) was performed to identify the level of correlation between leaf anatomical characters and basic orographic, geological, and bioclimatic habitat characteristics. DIVA-GIS software was used to extract 19 bioclimatic parameters from the WorldClim set of global climate layers. Our detailed analyses have shown that the studied populations are anatomically very well differentiated into the serpentine populations from western Serbia and carbonate populations from eastern Serbia. The regression analysis has shown that the geological substrate (serpentinites vs. carbonates) represents the most significant abiotic factor that is correlated with the anatomical differentiation of the populations in the studied area. Besides the geological substrate, bioclimatic parameters such as precipitation and habitat humidity are also highly correlated with the leaf anatomical characters, which was not the case with temperature.

Sesleria calabrica (Deyl) Di Pietro is a species belonging to the collective group of S. juncifolia s.l. which has been described recently for southern Italy where it is restricted to the Pollino—Orsomarso massifs. In this area S. calabrica is widespread between 1200 and 2280 m a.s.l where it is the dominant species in two grassland types, Jurineo mollis—Seslerietum calabricae ass. nov. (lower montane belt) and Anthyllido atropurpureae—Seslerietum calabricae ass. nov. (subalpine belt) which belong respectively to Festuco-Brometea and Elyno- Seslerietea classes. The presence of a southern Italy endemic sub—alliance of Seslerion apenninae is hypothesised.

A taxonomic study of the Sesleria juncifolia complex in the Italian Peninsula is presented, with a focus on southern Italian populations here named as Sesleria calabrica (DEYL) D! PIETRO comb. nov. et stat. nov. Karyological, morphological and anatomical characters were used for comparative analyses with populations of closely related species, such as S.juncifolia SUFFREN and Sesleria apennina UJI-IELYI occurring in the Italian Peninsula. Multivariate and univariate morphometric analyses, and qualitative morphological characters showed a distinct position of S. calabrica. Populations of S. calabrica differ in respect to various morphological characters of leaf and spikelet, such as the glume, lemma and palea length, stem length, the leaf sheath, leaf width, leaf thickness, and the total number of vascular bundles. Furthermore, previous karyological studies demonstrated that all the populations of both S. juncifolia and S. apennina examined are octoploid (2n=8x=56), whereas S. catabrica was found to be dodecaploid (2n= 12x=84). S. calabrica is strictly confined to the Pollino massif and the Orsomarso mountains in southern Italy, which represent the southernmost limit of the Sesleria juncifolia complex distribution area both in Italy and in Europe. In addition to S. juncifolia and S. calabrica, the recognition ofS. apennina as a taxon distinct from S. juncifolia is supported, at least for the area of the Apuan Alps.

A new species belonging to the genus Sesleria Scop., S. pichiana, was described as new for the Italian Flora. Hypotheses on its relationships with the Sesleria insularis aggr. from the Cyrno-Sardian Dominion and S. italica from the North-central Apennine were discussed.

An expression of plants response to light availability is their shade tolerance which refers to the capacity of a given plant to tolerate low light levels. Survival in a shaded environment can determine phenotypic consequences at morphological and/or physiological levels and such changes may be crucial to survive in heterogeneous and variable conditions. However, the potential plastic response of a given plant trait may be large but the observed plasticity may be lowered by resource limitations or environmental stress factors. In this context, the aim of this research was to analyze morphological, anatomical and physiological leaf traits variations of Sesleria nitida Ten. growing in different light conditions. In particular, plants growing in open (PO) and shade (PU) conditions were analyzed. The results show a 35% higher specific leaf area (SLA) in PU than in PO due to a 94% larger leaf area (LA). The higher height and width of the central and the major lateral vascular bundle in PO than in PU c...

Leaf mass per area (LMA) is an important variable in a set of coordinated leaf traits to determine plant species' ecological strategies. We hypothesized that LMA was the main predictor of the adaptive strategies of Sesleria juncifolia and S. nitida (Poaceae), growing on Mount Terminillo (Central Apennines) and cultivated ex situ. We broke LMA down into leaf anatomical components (i.e. leaf tissue density and thickness) and then related them to physiological traits. We found that the different habitats of the two species determine a different control of the anatomical components of the LMA variation. These differences are related to photosynthetic capacity, scaling linearly with leaf biomass investment per unit leaf area. On the whole, our study, taking into account the changes in LMA and its anatomical components, provides a trait framework which could be used to analyze adaptive strategies of other species in dry, mountain grasslands.

In this paper we typify and discuss 14 species and infraspecies names belonging to Sesleria sect. Argenteae (Poaceae). Lectotypes are designated for the names S. alba , S. anatolica , S. anatolica var. rossica , S. anatolica var. voronovii , S. doerfleri , S. gigantea , S. latifolia , S. latifolia var. serpentinica , S. pontica , S. robusta , S. sillingeri , S. vaginalis and S. wettsteinii . A neotype is designated for the name S. nitida . Previous typifications and holotypes for other names in S. sect. Argenteae are summarized.

After a close examination of the historical aspects of the typification of Sesleria caerulea, the correct names of the two allied species of the group are established as being S. caerulea (L.) Ard. and S. uliginosa Opiz. This permits unambiguous lectotypification of Sesleria. In addition, the types of the names S. albicans and S. uliginosa are designated.

Taxonomy of the genus Sesleria Scop. is complicated by the fact that most of the typical characters are of quantitative nature and under strong environmental control. In some cases, unequivocal det...

As part of the nomenclatural revision of the genus Sesleria (Poaceae), we have found that some names are still untypified. Thus, we have carried out a nomenclatural investigation which led to the designation of five lectotypes (for the names Festuca argentea , Cynosurus cylindricus , Sesleria argentea var. hispanica , S. elongata , and S. sphaerocephala ), three epitypes ( F. argentea , S. elongata , and S. sphaerocephala ) and one neotype ( S. autumnalis ). Concerning S. insularis a depth discussion was provided and this name was accepted to be lectotypified by Ujhelyi in a double-step typification . All the proposed types are in agreement with the current use of the names, and contribute to stabilize the nomenclatural framework of the genus.

In this paper we typify and discuss twelve names belonging to group Coerulans in the genus Sesleria (Poaceae). The holotype is established for S. tenerrima , and lectotypes are designated for the names S. bielzii , S. coerulans , S. coerulans var . borsae , S. comosa , S. klasterskyi , S. korabensis var . mrkvickana , S. krajinae , S. orbelica and S. orbelica var . pirinensis. Neotypes are selected for the names S. comosa var. weberii and S. haynaldiana . Images are provided for nine specimens selected here as types that are not available online. Previously published typifications for other names in the Coerulans group are summarized.

Karyological analyses of wild populations of Sesleria tenuifolia complex collected from throughout the Italian peninsula was performed to check the stability of the chromosome number along both geographical and ecological gradients. The chromosome counts showed that the Italian populations of the Sesleria tenuifolia complex consist of octoploid plants (2n=8x=56) and dodecaploid plants (2n=12x=84). The discovery of a dodecaploid chromosome number is the first for the genus Sesleria. The distribution of octoploid and dodecaploid populations follows strictly geographical boundaries and seems to be uninfluenced by synecological or physical factors. No overlapping between octoploid and dodecaploid populations was found; in fact, octoploid populations occupy northern, central and part of Peninsular Italy, whereas dodecaploid ones are restricted to the Pollino massif and the Orsomarso range, which together form the southernmost limit of the distribution area of the Sesleria tenuifolia complex.

The nomenclature of the linear-leaved species of the Sesleria juncifolia complex is one of the topics of ongoing research on the taxonomy, genetic variation, and coenology of the genus Sesleria . This paper deals with the typification of five names belonging to the S. juncifolia complex that are widely used in the taxonomical and phytosociological literature. The holotype of S. juncifolia Suffren has been located. The names S. interrupta , S. juncifolia Host, and S. tenuifolia are lectotypified. A neotype is selected for S. ujhelyi . Images for all type specimens are provided, including those for members of the complex that are already validly typified ( S. kalnikensis, S. albanica , S. apennina , S. calabrica ).

Einleitenden Bemerkungen zur systematischen Stellung von Hieracium wiesbaurianum Uechtr. folgt eine Charakterisierung dieser Art, wobei auch Unterscheidungsmerkmale nachstverwandter Arten angegeben werden. Lokalverbreitung im hercynischen Raum und Gesamtverbreitung werden durch Karten veranschaulicht. H. wiesbaurianum ist eine demontane und ozeanische Art, die in Thuringen ausschlieslich in Sesleria voria-reichen Pflanzengesellschaften beobachtet wurde. Ihr soziologisches und chorologisches Verhalten wird mit einigen dealpinen Arten sowie mit den nachsten Verwandten (H. bifidum Kit. und H. pallidum Biv.) verglichen. Remarks about the taxonomic position and a morphological description of Hieracium wiesbaurianum Uechtr. are given. Thereby the characters are presented to distinghuish the allied species. Maps illustrate the distribution in central Germany and the general distribution. H. wiesbaurianum is a demontane and oceanic species. It was observed in Thuringia exclusively in plant communities, in which Sesleria varia occurs abundantly. Its sociological and chorological behaviour pattern is compared with its nearest allies (H. bifidum Kit. and H. pallidum Biv.) and with some dealpine species of other genera.

After giving some considerations on the genus Lophodermium, four interesting graminicolous species are illustrated. New hosts, respectively Festuca Halleri All. for Lophodermium Sesleriae Hil. and Triticum durum Desf. for L. Tritici (Roum.) Weese are indicated; the diagnosis of L. alpinum (Rehm) is emended and the new species L. Castellanii is described on Sesleria disticha Pers. and S. caerulea Ard.

In the described experiments the interaction of 460 grass species with a mildew population obtained from Dactylis glomerata L. 'Motterwitzer' was examined. 420 species remained free of symptoms, while 40 species were susceptible. The most susceptible ones were Dactylis aschersoniana Graebner, Dactylis glomerata L., Dactylis glomerata spp. aschersoniana (Graebn.) Thell., and Dactylis polygama Horvat, but all showed differences in their behaviour. The unexpectedly low susceptibility of Dactylis woronowii Ovcz. should be examined again. Three grass species Bouteloua hirsuta Lag., Danthonia provinzialis DC., and Sesleria latifolia (Adam) Degen were also highly susceptible to cocksfoot mildew, while on wild grasses of the species Agropyron, Bromus, Festuca, Mibora, Poa, and Sesleria only few symptoms could be seen. Among cereals only barley could be infected by cocksfoot mildew. Not only in the wild form of Dactylis glomerata L. but also in the cultivated variety 'Motterwitzer', above 10% were found to be free from infection. Therefore the breeding of resistant varieties of Dactylis glomerata L. seems to be feasible.

Eleven sites were examined on limestone and non-calcareous drift. Dominant species and trellis diagram analysis of presence and absence data for all the 200 species recorded were not very useful for classifying sites according to their faunal similarities. Various groupings of the sites were made on the basis of differential species, and the principal groups were: Zygoribatula exelis-Eremeus oblongus group of mosses (except Grimmia) on limestone boulders; Rhodacarus roseus-Oppia sp. nr. obsoleta group of mulllike rendzinas under Sesleria on limestone cliff ledges, a rendzina-like soil under limestone grassland and a brown earth of low base status under Festuca-Agrostis on shallow drift; Platynothrus peltifer-Liochthonius perpusillus group of gleyed podsolic brown earths under Nardus on deep drift. In addition, the mull-like rendzinas could be characterised by the high frequency and dominance of Oppia translamellata. A small number of samples from Grimmia moss and lichens on limestone boulders indicated that the collembolan Anurophorus laricis may be characteristic of these sites.
