  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.

• 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.

  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.

  Our article provides data of 186 spreading cultivated taxa in Hungary. Among these, the spreading of 40 species in botanical gardens was not known until now. During our work, we examined the arboretums of Ti­szakürt, Szarvas and Erdőtelek, the agrobotanical garden of Tápiószele (located in the National Centre for Biodiversity and Gene Conservation), the botanical garden of the Eszterházy Károly Catholic Uni­versity in Eger and the De la Motte Castle Park in Noszvaj. We collected further data on the lately iden­tified Cardamine occulta and the spreading Veronica peregrina taxa, which spread mainly through plants sold in pots. Besides the already known two Juglans species, we found four new potentially spreading ones from the family of Juglandaceae (Carya cordiformis, C. ovata, Juglans cinerea and J. microcarpa). We also found seedlings and saplings in the case of all the investigated Abies species. We found the seventh Hungarian occurrence of Ludwigia grandiflora in the artificial lake of the Arboretum of Szarvas. The quantity of new occurrences reported in this paper highlights the need for further research in living collections in Hungarian botanical gardens.

  Géza Kósa was the curator of the dendrological collection of the National Botanical Garden in Vácrátót for 45 years. Thanks to his comprehensive knowledge of horticulture, plant science and garden-history, and his extensive collection garden experience, the Garden became the richest botanical garden in Hungary. Through his activities, he gained prestige for the importance of the collecting garden profession.
