Twenty-six different wild blackberry leaf samples were harvested from various localities throughout southeastern Poland. Leaf samples were assessed regarding their phenolic compound profiles and contents by LC/MS QTOF, and their antioxidant activity by ABTS and FRAP. Thirty-three phenolic compounds were detected (15 flavonols, 13 hydroxycinnamic acids, three ellagic acid derivatives and two flavones). Ellagic acid derivatives were the predominant compounds in the analyzed leaves, especially sanguiin H-6, ellagitannins, lambertianin C, and casuarinin. The content of phenolic compounds was significantly correlated with the antioxidant activity of the analyzed samples. The highest level of phenolic compounds was measured for R. perrobustus, R. wimmerianus, R. pedemontanus and R. grabowskii. The study showed that wild blackberry leaves can be considered a good source of antioxidant compounds. There is clear potential for the utilization of blackberry leaves as a food additive, medicinal source or herbal tea.

The paper presents new records of 24 vascular plant species from 11 Eurasian countries. One taxon (Orobanche laxissima) is reported from Armenia; one (Epipactis condensata) from Azerbaijan; two (Phragmites americanus, Polygala multicaulis) from Belarus; one (Stipa caucasica) from Egypt; one (Puccinellia hauptiana) from Kyrgyzstan; three (Aquilegia xinjiangensis, Geranium saxatile, Ranunculus songaricus) from Mongolia; one (Stipa roborowskyi) from Pakistan; three (Echinochloa muricata, Erigeron acris subsp. podolicus, Hypericum majus) from Poland; six from Russia, whereof one (Zanthoxylum armatum) from the European part of Russia and five (Chaerophyllum aureum, Elsholtzia densa, Poa compressa, Ranunculus subrigidus, Viola sororia) from the Asian part of Russia; two (Ludwigia repens, Sagittaria latifolia) from Slovakia; and three (Rubus ambrosius, Rubus camptostachys, Rubus perrobustus) from Ukraine. For each species, synonyms, general distribution, habitat preferences, taxonomy with remarks on recognition and differentiation of the species from the most similar taxa occurring in a given country, as well as a list of recorded localities (often far from the previously known areas), are presented.

The paper presents new records for 29 vascular plant species from 12 Eurasian countries. Seven taxa (Agave sisalana, Austrocylindropuntia subulata, Lagurus ovatus subsp. nanus, Opuntia stricta, Orobanche serbica, Oxalis articulata, Vitis × instabilis) are reported from Albania, one (Allium carinatum) from the Europaean part of Russia, six (Dipsacus fullonum, Gagea shmakoviana, Mentha × dalmatica, Thymus indigirkensis, Thymus sergievskajae, Viola × sukaczewii) from the Asian part of Russia, two (Agrostis sozanensis, Poa mustangensis) from China, two (Carex muskingumensis, Sedum rubens) from Poland, two (Crataegus macrocarpa, Dactylorhiza lapponica) from Romania, two (Oxygraphis delavayi, Ranunculus eryuanensis) from Nepal, two (Erigeron bonariensis, Ophioglossum vulgatum) from Tajikistan, one (Ranunculus olgae) from Kazakhstan, one (Najas guadelupensis) from Hungary, one (Orobanche bartlingii) from Armenia, one (Crataegus petrodavisii) from Azerbaijan and one (Amaranthus powellii) from Georgia. For each species, synonyms, general distribution, habitat preferences, taxonomy with remarks on recognition, and differentiation the species from the most similar taxa occurring in a given country, as well as a list of recorded localities (often far from the previously known areas) are presented.

The dandelions from Taraxacum sect. Erythrosperma are taxonomically well distinguished and ecologically restricted to warm and sunlit habitats of steppes, dry and sandy grasslands, and distributed in temperate regions of Europe and Central Asia, with some being introduced to North America. Despite the long tradition of botanical research, the taxonomy and distribution of dandelions of T. sect. Erythrosperma is still underexplored in central Europe. In this paper, by combining traditional taxonomic studies supported by micromorphological, molecular and flow cytometry analyses as well as potential distribution modelling we shed light on taxonomical and phylogenetical relationships between members of T. sect. Erythrosperma in Poland. We also provide an identification key, species-checklist, detailed descriptions of morphology and occupated habitats as well as distribution maps for 14 Polish erythrosperms (T. bellicum, T. brachyglossum, T. cristatum, T. danubium, T. disseminatum, T. dissimile, T. lacistophyllum, T. parnassicum, T. plumbeum, T. proximum, T. sandomiriense, T. scanicum, T. tenuilobum, T. tortilobum). Finally, conservation assessments performed using the IUCN method and threat categories for all the examined species are proposed.
