  So far, only one herbarium data and one flora mapping data on Kievan nettle (Urtica kioviensis Rogow.) has been known from the Southern Nyírség. Since 2004, the species has been detected in 14 flora mapping quadrats. Its data were also collected in winter because its habitats are more easily accessible on ice, its overwintering shoots are more noticeable, and they are strikingly morphologically different from the great nettle (Urtica dioica L.). Typical habitats were willow carrs (Calamagrosti-Salicetum cinereae), reeds (Phragmitetum communis), rush-beds (Typhetum latifoliae, Typhetum angustifoliae), tufted sedge communities (Caricetum elatae) and tall sedge meadows (mainly Caricetum acutiformis). The largest stocks live in reservoirs in secondary habitats. A significant part of the stocks is located in the wide valleys of the main watercourses in the area.

  In December 2018 the online Distribution atlas of vascular plants of Hungary (Atlas Florae Hun­gariae) was published. The database was built from more than 1 million data records. It mainly con­tains data from the Hungarian Flora Mapping Programme, but herbarium and literature data were also processed. Maps of species richness illustrate the taxonomic diversity of biogeographical areas and shows the differences of survey quality. After the Flora Mapping Programme ended, between 2016 and 2019, additional data from scientific articles were processed. 25% of new data originated from the ar­tic­le series “Contributions to the Atlas Florae Hungariae” in the Kitaibelia journal, which significantly bro­adened the distribution of some species. Records of Mesophile forest species (e.g. Allium ursinum, Dry­opteris dilatata) increased, as well as records of weed species (e.g. Euphorbia maculata, Senecio ver­na­lis) which can be attributed to their natural spreading. The most important future tasks are to create a reviewed list of taxa and extend data records with an attribute table containing all additional in­for­ma­tion. Until now the database website is presented only in Hungarian (http://floraatlasz.uni-sopron.hu). Registration is ava­i­lab­le for anybody, after sending a request via e-mail (atlas.florae.hungariae@uni-sopron.hu). There are different options (excel file by e-mail or online web form) on how to upload floristic data for registered users. Data is only accepted if required information (name of taxa, date, data publisher, settlement, CEU code) is filled out. Each record of uploaded data is revised by the website administrator and taxa spe­ci­alists. The English version of the webpage will be available in the near future.

  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.

  Results of nearly two decades of floristic research in the territory of Heves–Borsod Hills (Tar­na-vidék) and the northern foreground of the Bükk Mts are presented in this paper (altogether 4421 re­cords; BÁ: 1665, SJ: 2752). Several old literature records – partly supported by vouchers – are confirmed, e.g. Hypericum elegans and Lappula heteracantha from the Uppony Gorge, as well as Cephalaria tran­s­syl­va­ni­ca, Cypripedium calceolus, Diplotaxis erucoides and Plantago indica from the Heves–Borsod Hills and the nort­hern foreground of the Bükk Mts. Other former literature records (partly from the authors) are re­vi­sed. These revisions are mainly due to changes in taxonomic concepts of some genera in new keys (Carex, Cha­maecytisus, Epipactis, Molinia, Sorbus). Old literature and herbarium records of other significant taxa (Onos­ma visanii, Scutellaria columnae, Sorbus sp., Utricularia bremii/minor) are revised too. The new occurrence of Ferula sadleriana in the Uppony Gorge is probably the result of intentional seed dispersal. Of the many rare plants listed in our paper some are new for the flora of the region under study: Ag­ri­mo­nia procera, Alchemilla micans, Asplenium adiantum-nigrum, Astragalus austriacus, A. exscapus, Blysmus compressus, Carex appropinquata, C. cespitosa, Catabrosa aquatica, Centarea indurata, Dactylorhiza × as­cher­soniana, Epipactis voethii, Epipogium aphyllum, Equisetum hyemale, Festuca drymeja, Gagea bohemica, Gly­ceria nemoralis, Hesperis sylvestris, Myosotis caespitosa, Phegopteris connectilis, Platanthera chlorantha, P. × hybrida, Rosa gizellae, Scilla kladnii, Senecio doria, Solanum villosum, Taraxacum palustre, Triglochin pa­lustre. Two phytocoenological relevés representing the habitats of Myosotis caespitosa and Spiraea me­dia are presented. Currently known local distribution of some montane and forest-steppe elements are shown on maps.

  János Hulják prominent Hungarian botanist was born 130 years ago. He worked as teacher and director in elementary school at Pereces (today it belong to Miskolc). He played key role in the floristic exploration of Northern Hungarian Mountain Range. His huge herbarium collection was destroyed during World War II., only the exchange material was preserved (about few hundred sheets), mainly in BP and DE. Some vascular plant species [Centaurea huljakii J. Wágner, Sorbus huljakii Kárpáti, Galium × huljakii Jávorka and Pilosella auriculoides subsp. huljakii (Zahn) Soják] were named after him.

  The paper summarise occurrences of some rare invasive weeds of Hungary. We found currently second population at the Australian origin Chenopodium pumilio in Budapest (Zugló) in September 2016. Further, 27 occurrence data of 8 other species (Amaranthus deflexus, Echium maculatum, Lepidium densiflorum, Oxybaphus nyctagineus, Panicum dichotomiflorum, Portulaca grandiflora, Sarothamnus scoparius, Tragus racemosus) is also reported in the persent paper from the ‘Északi-középhegyég’ area (Northeast-Hungary), and some data from beside the Hungarian–Slovakian border, especially settlements, strongly disturbed places (especially road curbs, pavement cracks, train stations), indicating the Central European flora mapping system quadrate number. Voucher specimens were deposited in herbarium of Hungarian Natural History Museum, Budapest (BP).

  Some tropical Ludwigia species have been planted as ornamentals in Hungarian thermal springs since the 1920s. Although they have become naturalised or even invasive in a few places, their specific identity remained generally uncertain. Our herbarium and field studies revealed that three species of alien water-primroses occur in Hungary. The most frequently planted one is Ludwigia repens, which is, however, a sporadic species in its native distribution area. We have found this species in several parts of the country. Although a few escaped and self-sustaining populations were also observed, this species has appeared to be non-invasive so far. Ludwigia grandiflora appeared in Hungary at the beginning of the 2000s. At the moment it is known from three localities, though spreading rapidly, becoming already invasive in its locality at Tata city. A similar species, L. peploides has recently been reported from two localities, where it forms small stands; the success of its naturalisation can be assessed in the future. We found no evidence for the Hungarian occurrence of L. alterniflora that had been published from Eger city. Therefore we suggest deleting this species from the current Hungarian checklist.

  In this paper I present occurrence data of Epipactis species in the Keszthely Mts which were collected during the last four years. Ten species had literary or herbarium data from the area previously, all of them has been confirmed (Epipactis atrorubens, E. helleborine, E. leptochila, E. microphylla, E. moravica, E. muelleri, E. palustris, E. purpurata, E. nordeniorum, E. voethii) and another five species (Epipactis albensis, E. neglecta, E. peitzii, E. pontica, E. tallosii) furthermore a hybrid (Epipactis ×reinekei) were found newly on the area.

• Historical occurrence of Spergularia echinosperma, a rare Nanocyperion species in Hungary

  Three species of the genus Spergularia have been known from Hungary. The most widespread one, Spergularia rubra (L.) J. Presl et C. Presl occurs on young sandy fallow fields and other disturbed habitats.  The other species, S. marina (L.) Bess. and S. media (L.) C. Presl, occur sporadically in saline grasslands, and both have been recently spreading along salted roads. During a revision of the genus Spergularia in Hungarian herbaria, specimens of the species S. echinosperma (Čelak.) Asch. et Graebn. were found. It is a rare species previously known to occur only in Czechia and Germany and to be extinct in Austria and Slovakia (a few occurrences along the Morava and Danube rivers between 1909 and 1953). However, it was recently discovered in Western Siberia and Kazakhstan. It is a typical mudflat plant that occurs on exposed sandy shores of water bodies. Two herbarium sheets collected by Gyula Tauscher from near the village of Ercsi (riverbank of the Danube) in 1903 were found in the Carpato-Pannonicum collection of the Hungarian Natural History Museum. In addition, a new specimen was found, collected in Slovakia (Danube near Šamorín, collected by Mihály Résely in 1868) at the vicinity of the Hungarian border. The species was not confirmed during a field inspection of the target localities in Hungary; therefore, we have to consider it extinct in the country as well as in the whole Pannonian Basin. Recently, S. echinosperma was split into two subspecies – subsp. echinosperma and subsp. albensis. The subsp. echinosperma is probably restricted to fishponds in the SW part of Czechia and subsp. albensis occurs mainly in the floodplains of the river Elbe in Germany. The extinct populations of S. echinosperma in the Pannonian Basin belonged to the subsp. albensis. This taxon is morphologically close to S. rubra but can be reliably distinguished by densely verrucose seeds and shorter than wide stipules.

  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.

  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.
