  We report new floristic data collected from the Zemplén Mountains between 2004–2022. Altogether, 1215 occurrences of 133 species were recorded from 33 Central European Flora Mapping quadrats. We present occurrences of so far not reported or rare species, e.g., Carex appropinquata, C. cespitosa, C. disticha, Centaurea stenolepis, Scabiosa columbaria, Tephroseris aurantiaca. We put special emphasis on occurrence data of geobotanical importance, such as Anthriscus nitidus, Echium maculatum, Lunaria rediviva, Nepeta pannonica, Oreopteris limbosperma, Petasites albus, Primula elatior, Thlaspi jankae, Veronica montana, as well as newly rediscovered species based on archive data: Cirsium rivulare, Parnassia palustris. We mention common species, which are lacking data from the area, e.g., Adoxa moschatellina, Allium flavum, Cardamine amara, Dipsacus fullonum, Galanthus nivalis. Moreover, we report numerous new occurrences of taxa typical to the Zemplén Mts.: Aruncus dioicus, Huperzia selago, Lycopodium annotinum, Securigera elegans etc. We complete the enumeration with additional data from the literature and herbaria.

  The paper deals with the species found during cryptogamic flora mapping in 2023 that are remarkable from a floristic, taxonomic or conservational point of view. We present data from the Bükk Mts of two Trapeliopsis species which appear to be rare in Hungary. Multiclavula mucida, which is ap­parently a rare basidiomycete lichen species in Europe that prefers humid, montane habitats was dis­covered in the Mecsek Mts as a new species for the Hungarian flora. Of the knothole moss, Anacampto­don splachnoides, which is now thought to be entomophilic, we communicate the only extant popula­tion from Southern Transdanubia. We report the first occurrence of the atlantic-mediterranean Lepto­don smithii from the Hungarian side of the Great Hungarian Plain. Numerous data of the corticole Neck­era pennata indicate that in Hungary the distributional centre of this species is situated in the county of Baranya in the lowlands. New data from the Bükk Mts underline that in the Pannonian region Buxbaumia viridis is primarily a terricole species of acidophilous beech forests. We communicate the first occurrence from the lowlands of the alien lignicolous Sematophyllum adnatum which is danger­ous­ly spreading in Europe, at the same time one of the most vigorous populations in the Pannonian region. The third Hungarian occurrence of Callicladium haldanianum, a species that seems to spread in bogs, as well as the second occurrence of Racomitrium lanuginosum, growing abundantly on an ande­site boulder scree in Mátra Mts, are also reported here. Of Phegopteris connectilis we present in photo­graphic docu­mentation the first extant population from Southern Transdanubia, and we discuss whether the first publication from Mecsek Mts is correct or exact. In addition to listing the floristic data, we also briefly discuss the (mis)use of distribution data in the context of climate change, the difficulties of distinguish­ing the microtaxa of some pteridophytes, e.g. Asplenium adiantum-nigrum agg. and Dryop­teris affinis agg., and we correct one of our previously published, erroneous Hedwigia stellata data. Some interest­ing data of other taxa (such as Leucobryum glaucum, Palustriella commutata, Tetraphis pellucida, Gym­nocarpium robertianum, Ophioglossum vulgatum) are also mentioned in the paper.

• Data on the occurrence of alien plants in Western Transdanubia (Hungary)

  In his publication the author provides data on the occurrence of 11 alien species in Wes­tern Transdanubia. Three of these species (Euphorbia maculata, Euphorbia peplus, Muscari armenia­cum) were observed to have spread rapidly in the past decade. It can be concluded that 4 species (Ar­temisia annua, Crocus banaticus, Polycarpon tetraphyllum, Veronica filiformis) have reached a state which is close to naturalization, while the other reported species (Euphorbia lathyris, Senecio inaequi­dens, Silybum marianum, Veronica peregrina) are casual in this region at present.

• Occurrence and habitat conditions of Gagea minima along the Sorok stream (W Hungary)

  Gagea minima (L.) Ker Gawl. is a Eurasian bulbous species. It occurs sporadically in Hun­gary, but so far only one current occurrence is known from the Western Transdanubia. In recent years, a large metapopulation has been found in a 15 km long section of the Sorok stream. Its habitat is the high sandy bank above the stream, where it lives mostly in nitrophilous vegetation under non-native tree species. Its long-term persistence in this secondary habitat may have been facilitated by its bulbs, which may have been regularly dispersed by periodic disturbance. Myrmecochory may also have played a role in the local establishment of subpopulations. A number of recently found populations indicate that data on the distribution of the species is still incomplete. The lack of data is probably due to its short flowering period and relative inconspicuousness. Gagea minima is considered a valuable relict species in the altered environment of the Sorok stream and its surroundings.

• Astragalus vesicarius and other new taxa to the flora of the Vértes Mountains (Hungary, Transdanubian Mts)

  A conservation survey on the condition of steppe and forest-steppe habitats in the Vértes Mts revealed several plant species from the flora of the area that have not been reported before. From a phytogeographical point of view, the most important is Astragalus vesicarius, whose small population in the Vértes fits very well into the native distribution pattern of the species in Hungary. Another important steppe plant is Stipa dasyphylla, which is found in two locations in the Vértes Mts. Besides other taxa of conservation interest (Orobanche teucrii, Phelipanche purpurea, Rosa hungarica), some under-recorded species (Cerastium tenoreanum, Stellaria pallida), and some spreading weeds (Elymus elongatus, Euphorbia lathyris) enrich our knowledge of the flora of the area.

• Contributions to the subspontaneous occurrences of Malva moschata (Malvaceae) in Hungary

  Malva moschata is an alien species in Hungary, seldom cultivated as garden ornamental plant. Although considered as occasional escapee from cultivation, Hungarian literature has only cited Budapest as an example of such cases thus far. During a revision of the Malva collection in BP herbarium, several specimens were traced (mostly erroneously labelled as Malva alcea) which demonstrate subspontaneous occurrences of the species, primarily from the Transdanubian region (Hungary). The vouchers are hereby listed, arranged in alphabetical order of localities (settlements). Literary connections, if relevant, are briefly discussed.

• Data on the pioneer vegetation of the Lake Velence

  203–208

  Lake Velence is one of Hungary's largest saline lakes. Part of its natural dynamics is that certain parts of the lake bed regularly dry out, providing pioneer surfaces suitable for the emergence of plants of the mudflats and drying (saline) ponds. During the particularly dry year of 2022, the water level was per­manently and significantly low, allowing to study the vegetation of the dry lake bed. In the first half of the last century, the natural vegetation of the lakeshore (including salt steppes) was studied, but there are very few records of the pioneer species of the lake bed. The salt steppes around the lake have now largely declined, but due to low water levels, some of their characteristic species are still present in the lake bed (though, usually in low number of individuals). Examples include Crypsis aculeata, Cyperus pannonicus, Suaeda pannonica, the once abundant Suaeda prostrata, and the previously rare Crypsis schoenoides and Spergularia salina. Spergularia maritima was once widespread but currently not found in the lake bed. Although, Schoenoplectus litoralis is not a member of the ephemeral vegetation, but is a characteristic plant of the littoral zone of Lake Velence. This species probably appeared therein the middle of the last century and is currently spreading.

  In this publication, the author provides occurrences of geobotanical importance from the North Hungarian Mountains collected in the spring of 2023. First occurrence for the following species was recorded: Helleborus dumetorum from the Cserhát Hills, Lunaria annua from the Mátra Mts. and Dryopteris affinis from the Bükk Mts. Ranunculus aquatilis was found again in the Bükk Mts., where it had been collected more than 100 years ago, and Rubus saxatilis was found for the fourth time in the Zemplén Mts.
