  During the study of the weed flora of garden centers in Hungary (among 2017–2020), remarkable populations of Cardamine occulta Hornem., a new alien for the Hungarian flora were found. C. occulta was present altogether in 51 of the 53 visited sites. Dominantly the regularly irrigated and continuously moist microhabitats (pots, containers, muddy surfaces of geotextile-covered beds etc.) were colonized. During the revision of our recently collected specimens, deposited in JPU and DE herbaria as Cardamine hirsuta L., further individuals proved to identical with this till overlooked species. One of them (27.08.2004., Heves county: Eger [8088.3; 8188.1], coll. by A. Schmotzer, deposited in DE collection) proved to the third documented occurrence in Europe, comparing to the accessed literature data. Eclipta prostrata (L.) L. and Urtica membranacea Poir. are also new aliens for the Hungarian flora. Several introduced individuals of these taxa were found in containers of imported thermophilous woody ornamentals at 4 and 2 sites, respectively. Tens of individuals of Eclipta prostrata were also found in a sapling-bed at another site. New populations of scarce or rare Euphorbia prostrata Aiton, E. serpens Kunth and Veronica peregrina L. were also documented.

  New localities of 4 rare taxa are presented from Eastern Hungary. The species are new for the flora of particular floristical regions, specifically: „Eupannonicum”: Polystichum braunii; „Crisicum”: Aphanes arvensis; „Samicum” and „Nyírségense”: Agrimonia procera. Three new localities of the alien species Montia linearis in Hungary are presented. This species is still very rare in Europe, reported only from Poland, Denmark and Hungary.

  This paper reports new floristic data of 161 taxa. Most of these data were collected between 2011–2013, and are coming from the northern edge of the floristic region 'Crisicum', the NE part of the Great Hungarian Plain, which is a little-known area from a floristic point of view. 43 CEU quarterquadrates and territory of 35 settlements are represented by the dataset. The paper reports occurrence localities for legally protected (e.g. Ophioglossum vulgatum, Stellaria palustris, Ranunculus polyphyllus, Thlaspi jankae, Lathyrus palustris, Elatine spp., Lycopsis arvensis, Lindernia procumbens, Cirsium brachycephalum, Cyperus pannonicus), strictly protected (Armoracia macrocarpa, Vicia biennis) and some little-known (e.g. Cardamine parviflora, Reseda luteola, Melilorus dentatus, Veronica catenata) taxa. Numerous data of alien species (e.g. Lepidium densiflorum, Euphorbia maculata, Sicyos angulatus, Erechtites hieracifolia, Elodea nuttallii, Elymus elongatus, Eleusine indica, Sorghum halepense, Eriochloa villosa) are also published. The most important data are documented by voucher specimens deposited in herbarium of Debrecen University (DE).

  This paper reports new floristic data of 207 taxa. Data collected between 2005 and 2015; originated from the central part of the floristic region ‘Crisicum’ (i.e. the E part of the Great Hungarian Plain), which is a currently poorly studied area of Hungary from a floristic point of view. The paper reports occurrence localities for some rarities such as Asplenium trichomanes, Marsilea quadrifolia, Sisymbrium polymorphum, Viola stagnina, Gentiana pneumonanthe, Elymus elongatus, Montia fontana subsp. chondrosperma, Ranunculus rionii, Ranunculus illyricus, Myagrum perfoliatum, Sedum caespitosum, Vicia biennis, Dorycnium herbaceum, Oenanthe banatica, Peucedanum cervaria, Echium italicum, Digitalis lanata, Valerianella rimosa, Craex buekii, Cephalaria transsylvanica, Cyperus pannonicus.
