  Dactylorhiza Necker ex Nevski is a complex genus. The taxonomy of these dactylorchids is widely considered to be complicated due to relatively high morphological variability within species and high frequency of hybridization between species. During a floristic survey of the Valea Morii (Morii Valley, Malomvölgy) Nature Reserve in June 2017, a population of Dactylorhiza traunsteineri (Saut. ex. Rchb.) Soó, a species with uncertain presence in the Romanian flora was found. In the Morii Valley, this narrow-leaved marsh-orchid was encountered in fen-patches, in phytocoenoses of the plant association Orchido-Schoenetum nigricantis Oberd. 1957. Due to the cool and wet microclimate of the Morii Valley, many glacial relicts and other plant rarities (e.g. Tofieldia calyculata (L.) Wahlenb., Swertia perennis (L.), Liparis loeselii (L.) Rich., Ophioglossum vulgatum L. Schoenus nigricans L.) had been able to survive on strongly humid places on calcareous soils. This study reports the first occurrence of D. traunsteineri in Romania confirming the presence of a highly debated taxon. We also discuss the morphological features, habitat preference and conservation status of this new species in the Romanian Flora.

  Dr. Sándor Polgár was the most outstanding botanist of Győr county (NW Hungary). He provided important results in floristic studies, phytogeography, taxonomy and in the research of alien plants. „Győr megye flórája” („Flora of Győr county”), published in 1941, was one of the most important monography in his period. He is the author of the rare, hybridogenous species Ornithogalum ×degenianum, known only from Hungary. His private herbarium was one of the biggest in Hungary with more than 20,000 specimens. As a teacher he taught geography and nature studies in his home town Győr between 1900 and 1935. Because of his Jewish origin, he was a victim of the holocaust in 1944.

  In the 20^th century Sándor Polgár was one of the most outstanding researchers of adventive plant species in Hungary. He wrote nine publications in this theme. In the industrial environment of his home town Győr (NW Hungary) he found tropical species, most of them were southern-American origin. The richest alien flora came around the oil factories of the town. He reported 65 taxa new for the Hungarian flora, four of them were new for Europe too. He was a great expert of problematic Solanum, Amaranthus and Chenopodium genera.

  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.

  In this paper a review of the nomenclature, etymology, taxonomy, morphology, histology, life cycle, phenology, reproduction, habitat preference, biotic interactions, biologically active compounds, micropropagation, application possibilities and conservation status of Siberian flag (Iris sibirica L.) can be found. Leaf traits, phenological data, seed-set, thousand-seed weight, germination, growth rate and soil characteristic data are published based on original observations:

  • Leaf area is between 25,3 and 52,9 cm², its dry mass is 232 and 272 mg/g, specific leaf area is 14,5 and 15,0 m²/kg; based on measurement of 5–5 leaves of sibirica, collected from Tapolca and Létavértes (Hungary) in May of 2014.
  • Based on herbarium dataset, blooming of sibirica begins at the end of April and lasts to early-July, contrary to the literature data (May–June).
  • Capsules contain (0–)58–76(–121) fertile seeds. (20–)60–80(–90)% of ovules develops to (seemingly) viable seeds, meanwhile the other ovules remain as aborted ones or develop to infertile seeds (probably because of absence of resources); based on fruits collected from Regéc (Hungary) in 2014 and 2015.
  • Thousand-seed weight of sibirica is 8,8298–11,2914 g (based on 3×100–100 seeds collected from Regéc and Tapolca in 2014 and 2015), which is lower value than the literature data.
  • In our germination test (50–50 seeds sowed to wet soil, after different treatments) 14% of scarified seeds, 6% of scalded seeds, 4–4% of imbibed and control seeds, 0–0% of cooled and refrigerated seeds are germinated. Scarified seeds germinated in the 8–26^th days, imbibed seeds 15–19^th days, control seeds 16–20^th days, scalded seeds 20–23^th days after sowing. It seems that scarification stimulates, meanwhile temperature-treatments inhibit the germination. Until 18 weeks the seedlings grow to 30 cm (in mean) and develop 5–7 leaves (in mean). After the 14^th week, the first and littlemost lateral leaves are necrosed.
  • Analyses of soil samples collected from 17 locations of sibirica in Hungary, suggest that the species prefers highly acidic to slightly alcalic, lime-free to highly calcareous soils with generally high amount of humus and clay, different amount of phosphorus, potassium and nitrogen and low concentration of salt.

• Distribution and flora of areas with alkaline and saline soils in the Mezőföld, Hungary

  Areas with  alkaline and saline (solonetz and solonchak) soils occupy substantial areas in the westernmost, Trans­danubian part of the Great Hungarian Plain (Mezőföld). To this date, the flora and vege­tation of only two localities have been studied in some detail, while the rest has remained largely unknown in this respect. In this paper, I provide brief descriptions of these little-known areas and present a list of halophytes with distribution data from the last 17 years. The names of the plants are followed by the name of the township and the geographical location where the plant was found, the code of the grid cell of the Central European Flora Survey grid that includes the location, and in selected species, the year when the species was first recorded. The list is arranged in alphabetical order irrespective of taxonomy. The occur­rence data indicate that the floras of these saline-alkaline areas represent only subsets of, but in combina­tion are almost identi­cal to the overall flora of similar habitats in the Sárvíz plain.

  Climbing asparagus (Asparagus verticillatus L.) a new adventive species to the Hungarian flora was recently discovered in the city of Pécs (South Hungary) in 2011–2012. Taxonomy, morphological description and current localities of the species are presented in this paper. A. verticillatus is a mediterranean-submediterranean species native in Balkan Peninsula, Eastern Europe, Western- and Middle Asia. The species is a popular ornamental plant in Hungary, but no data was available about its escape or naturalisation in the country so far. Herbarium specimens from Hungary were collected so far mostly from botanical and private gardens; only one specimen was collected in a dry grassland along a roadside in the city, respectively. The newly discovered small populations are located mostly in secondary dry grasslands, at the edges of vineyards and private gardens on the southern slopes of the Mecsek Mts and only one specimen was found far from the residential area in natural vegetation. Because climbing asparagus is a frequently planted ornamental plant in several locations of Pécs, further escape, naturalisation and persistence of the species is possible in the future.

  The first occurrence of blue lettuce (Lactuca tatarica (L.) C.A. Mey.) is reported from Hun­ga­ry. Information on its taxonomy, morphology, distribution, habitat preference and nature conservation aspects is presented. The European local spread of this Eurasian and North American species started at the end of the 1800s. The first localities were reported from the shores of the Baltic and North Sea. Its alien occurrences in inland European regions have been noticed since the 1920s. As L. tatarica have pre­viously been known from the neighbouring territories of Slovakia and Austria, its appearance in Hun­gary is not at all unexpected. However, the species was found (August 2018) in the southern part of Csongrád county, i.e. far away from the above-mentioned countries. Due to the species’ habitat preference (ruderal ground), ecological requirements and successful vegetative propagation, which correspond to foreign observations, its future spread is highly probable.
