As part of the PADAPT project, the authors compiled the invasion biological database of the alien vascular flora of Hungary, which contains the nativeness, residence time, introduc- tion mode and invasion status of 878 alien or cryptogenic taxa. In the absence of adequate evidence, the classification of some species was only possible into uncertain, transitional cat- egories. The definitions of most categories are compatible with several international termi- nologies, but are primarily based on Central European traditions. Of the 560 taxa that have already been naturalised in Hungary, 85 are invasive, and 22 of them are transformer alien vascular plants. Only 5 of these transformers are included in the European list of Invasive Alien Species of Union concern (Ailanthus altissima, Asclepias syriaca, Elodea nuttallii, Heracleum mantegazzianum and H. sosnowskyi), which require uniform preventive interventions and treatments throughout the continent, while the rest of transformers in Hungary (e.g., Robinia pseudoacacia, Fallopia × bohemica and Solidago gigantea) draw attention to the unique, local and/ or regional invasion biological situation of the Pannonian Basin and Central Europe.
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.
Genus Barbilophozia is reported and described as a new generic record for India from union territories of Jammu and Kashmir, Western Himalaya. Two species, namely Barbilophozia lycopodioides and Barbilophozia barbata are described in the present communication.
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.
Abstract
Scale insect (Hemiptera: Coccomorpha) fauna on imported tropical and subtropical fruits collected between 2013 and 2021 was investigated. The study revealed two armored scale insect (Diaspididae) species new to the fauna of Hungary (namely Aonidiella citrina (Coquillett) and Lepidosaphes pinnaeformis (Bouché)). Number of species of the Hungarian scale insect fauna increased to 279, while number of species collected on imported tropical and subtropical fruits changed to 16.
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.
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.
Thymus saturejoides is an endemic species of the Lamiaceae family, native to Morocco and Algeria with a restricted distribution to the High Atlas, Middle Atlas, Anti-Atlas, Middle Atlantic Morocco, and the Saharan Atlas regions of Morocco, and the Aures Mountains in Algeria. This research focused on taxonomy, ethnobotany, chemical compounds, and biological and pharmacological actions of T. saturejoides. Folk medicine has documented continued use of this plant species. The review summarises the scientific literature and experimental research from the databases including Google Scholar, Semantic Scholar, ResearchGate, Academia.edu, PubMed, and PubFacts. Finally, we have provided a complete document on ethnobotany, phytochemistry, and biological properties fields of T. saturejoides.
Abstract
During survey from 2013 to 2018, Cynodon dactylon at Shahjahnapur, Azamagarh, Oplismenus burmannii at Shahjahnapur, Arundo donax at Deoria and Ocimum cannum at Gorakhpur were observed with phytoplasma suspected symptoms. The maximum disease incidence (34%) was recorded at Deoria District in case of A. donax plant with witches' broom symptom. The nested PCR using universal primer pairs (R16F2n/R16R2) confirmed the phytoplasma association with all the suspected samples. Further BLASTn and phylogenetic analysis of the sequences revealed the association of 16SrXIV-A subgroups phytoplasma with C. dactylon, O. burmannii and phytoplasma belonging to 16SrI-B subgroups with A. donax and O. cannum plants in the present study.
Abstract
Anauchen (?) kozari n. sp. is described from Luang Prabang province, central Laos. This new species is temporarily placed in the genus Anauchen due to the similarity of its apertural barriers to those of A. messageri (Bavay & Dautzenberg, 1904). Boysidia gereti Bavay & Dautzenberg, 1904 is a junior synonym of Anauchen rochebruni (Mabille, 1887) (originally described as Hypselostoma).
