Following the work of Tatár (1939), no new revised and detailed list was made of endemic plants of the Pannonicum phytogeographical region, which takes into account the latest research results. A survey of vascular plants endemic and subendemic to the Pannonicum is presented here based on a critical revision of published and sometimes unpublished data on contemporary taxonomic and chorological knowledge. For this, it was necessary to review the delineation of Pannonicum and the problem of drawing the boundaries. I would also like to draw the attention to the Pannonian flora islands outside the Carpathians, which descend along the sandy alluvium of the Danube. The research covers 11 countries: Austria, Croatia, the Czech Republic, Hungary, Romania, Serbia, Slovakia, Slovenia and a small part of Bosnia and Herzegovina, Ukraine and Bulgaria (flora islands). The final evaluation of endemic status was made for 225 taxa of vascular plants, including 143 taxa confirmed as endemic or subendemic to the Pannonicum, 5 narrowly distributed taxa shared endemic of the Pannonicum and western part of the Carpaticum and 77 taxa are not endemic according to current taxonomic and phytogeographical knowledge (the list does not include hybrids). The final list of endemic and subendemic taxa includes 42 species, 29 subspecies and 73 apomictic species (including 47 taxa of Sorbus and 23 taxa of Taraxacum). Tatár mentions 55 taxa (without apomicts) of which only 29 (53%) are still considered endemic today. In terms of habitat preferences for (sub)endemic taxa most plants (excluding apomictic taxa) occur in rocky or sandy habitats.

Eighteen species of foliicolous lichens have been mentioned earlier from the Fiji Islands in various literature sources and based on collections since 1860. Current records originate from the collections of Göran Thor from 1985 and Sarolta and Tamás Pócs from 2003. G. Thor visited lowland rainforests of Island Viti Levu, S. and T. Pócs collected also in higher elevations (up to ca 1,000 m) in submontane, montane and montane mossy (cloud) forests on Kadavu, Taveuni and Viti Levu Islands. These relatively small collections (of ca 300 and 150 leaves, respectively) resulted in 78 species of the 85 lichen species known today, among them 67 species are new for the foliicolous lichen flora of the area in this publication. New taxa described are Phylloblastia taveuniensis Farkas, Porina kadavuensis Farkas, furthermore the genus Tamasia Farkas (Ramalinaceae) and species Tamasia fijiensis Farkas containing cyanobacterial photobiont.

The categorisation of plant species according to their life form has a long history in plant ecology. The most popular system worldwide and also in Hungary is Raunkiaer’s categorisation according to the position of buds (meristems) surviving the adverse season. The original system contains only seven categories, resulting in high diversity within each category. Therefore, different refinements are suggested. This paper aims to apply an internationally accepted refinement of Raunkiaer’s categorisation, the Ellenberg and Mueller-Dombois system, to the Hungarian flora.

The Teucrium genus is an important source of essential oil-bearing plants. The essential oils of this genus are endowed with important phytochemical diversity, exert widespread biological properties, and have several uses in traditional medicine. Teucrium takoumitense is an endemic aromatic and medicinal plant, grown in a very limited area in southeastern Morocco. To the best of our knowledge, there is no published report on the phytochemical or biological studies of Teucrium takoumitense essential oil (EO) harvested from the Errachidia region in Southeast Morocco. GC/MS analysis, total phenolic compounds, antioxidant, anti-inflammatory, and antibacterial tests on the EO of this plant were carried out in this study. The results of GC/MS analysis showed that β-ocimene (10.12%), δ-bisabolene (8.35%), linalool (8.16%), β-eudesmol (8.05%), and δ-cadinene (7.89%) are the major compounds in the EO. Important antioxidant activity (IC50 DPPH = 2.4 mg/mL, IC50 ABTS = 1.58 mg/mL, IC50 FRAP = 0.71 mg/mL, and TAC value = 230.72 AAE mg/g EO) and potent anti-inflammatory effect evaluated by phenol induced inflammation in rat ears were induced by the volatile oil. Moreover, the volatile oil induced antibacterial activity against Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus. In conclusion, Teucrium takoumitense EO was found to be rich in volatile compounds and exert antioxidant, anti-inflammatory, and antibacterial properties. More studies are recommended to be evaluated on the extracts of this plant and conservation interventions need to be carried out to maintain its sustainability.

During the study on flora of Hyrcanian forests and collecting specimens in order to plant in Hyrcanian habitat of National Botanical Garden of Iran, among the collected specimens, some specimens of the Quercus castaneifolia (Chestnut leaved oak) from south of Sari city in Mazandaran Province in North of Iran seemed to be interesting and were different from the other known subspecies of Q. castaneifolia. Results of morphological study of the species showed that there are clear differences between shape of the cupule and some micro-morphology traits of the leaf trichomes and pollen. Thus, based on the botanical traits of the new taxon and according to summarised data from the obtained results of the other subspecies and variety of the Q. castaneifolia, this taxon was identified as a new subspecies and named: Quercus castaneifolia subsp. recurvatus Zare et Panahi which is described here. The new taxon is related to Quercus castaneifolia subsp. castaneifolia var. castaneifolia and well characterised by having different shape and arrangement of the involucral bracts on the acorn cupule comparing with the others.
在对Hyrcanian森林植物区系的研究和为在伊朗国家植物园Hyrcania栖息地种植而采集标本的过程中，来自伊朗北部马赞德兰省萨里市南部的栗叶栎（Quercus castaneifolia，Chestnut lead oak）的一些标本似乎很有趣，并且与已知的其他栗叶栎亚种不同。形态研究结果表明，小杯的形状和叶片毛状体和花粉的一些微观形态特征存在明显差异。因此，根据新分类单元的植物学特征，并根据从栗叶栎的其他亚种和变种获得的结果总结的数据，该分类单元被鉴定为一个新的亚种，并命名为：栗叶栎亚种。recurvatus Zare et Panahi。新分类单元与栗叶栎亚种亲缘关系密切。栗叶变种栗叶，其特征是与其他品种相比，在橡子杯上的总苞片具有不同的形状和排列。

Nutlet pericarp structure is important in the taxonomy of Lamiaceae (Labiatae) at different taxonomic levels. Within the family it has also been found that variation in pericarp structure is strongly correlated with the phylogenic results obtained from molecular DNA analyses. The genus Nepeta L., with more than 200 species mainly centred in SW Asia, is one of the taxonomically most complex genera within the family. Traditional taxonomic treatments of Nepeta are mainly based on gross morphology. As in other groups of Lamiaceae, pericarp structure provides some of the diagnostic characters in this genus. In order to investigate patterns of pericarp evolution within Nepeta, we used scanning electron microscopy to examine nutlet surfaces and pericarp cross sections and explored variation of these characters against a molecular phylogeny based on ITS sequences. Based on this phylogenetic analysis, Nepeta in its present circumscription is not monophyletic. Evolutionary trends in structure of nutlet pericarps are apparent although they require confirmation with more robust phylogenies. In particular, nutlets with tuberculate/thorny-like pericarp may have evolved once within this genus, in the common ancestor of five of the six subclades identified within Nepeta, and have been lost independently several times. We also show that evolution of tubercules in Nepeta is not related to plant life span. Our results also indicate that more genetic markers (both plastid and nuclear) are necessary to reconstruct a reliable and robust organismal phylogeny.

The lack of knowledge on the traits related to the germination and establishment of native plant species represents obstacles to restoration. Seed mass, germination and emergence variability from two characteristic grasses (Festuca vaginata and Stipa borysthenica), and two dicots (Centaurea arenaria and Dianthus serotinus) of Hungarian sandy grasslands from altogether 34 localities were tested. Our results showed that seed mass had a significant positive effect on germinability of the dicots and on seedling emergence of all species. The laboratory germination capacity of S. borysthenica was low due to dormancy. We found a significant variability among seed traits and emergence between localities in all the species except for the germination of S. borysthenica. This significant variation among populations might be explained by local adaptation or maternal effects. We conclude that germination under laboratory-regulated conditions is a good predictor of seedling emergence for restoration projects, but limited to species with non-dormant seeds.

The Persian walnut, also known Juglans regia of the genus Juglans is cultivated throughout the temperate regions of the world for its high-quality wood and edible nuts. Genetic diversity, structure and differentiation of cultivated walnut are important for effective conservation, management, and utilisation of germplasm. Recent study on genetic diversity and genotype differentiation in Persian walnut of Iran, revealed that these genotypes can be differentiated by ITS and ISSR, however, these markers show a low degree of genetic variability. ITS sequences revealed a lower degree of genetic difference of the studied Persian walnut genotypes compared to that of ISSR molecular markers. Therefore, it is important to investigate these genotypes by the other molecular markers to find out which one can produce more data on genetic structure and variability in these important genotypes. For the same reason, we continued this study by using cp-DNA (psbA-trnhG) gene, IRAP, and REMAP. To provide barcode for Iranian genotypes of Juglans regia is an other objective of this study. For IRAP and REMAP analyses studies, we randomly selected 60 plants from 6 populations including 3 wild and 3 cultivated populations. For cp- DNA analysis we used 21 plants of Juglans regia randomly selected from 6 studied populations. The present study revealed a high level of genetic variability in Juglans regia genotypes in those sequences investigated by IRAP and REMAP molecular markers. We reported that IRAP and REMAP molecular markers cannot be efficiently used in walnut germplasm genetic screening.
