  In this paper, we presented the results of our floristic survey in West-Hungarian region. The data were collected between 2005 and 2015 and supportted with herbaria or photo-documentation. This paper reports new floristic data of 98 taxa from West-Hungary with altogether 172 field-collected data records. In the survey we focused on little-known taxa with a phyto-geographic importance. For some taxa we checked the herbarium specimens of Savaria Museum and Natural History Museum of Budapest. During our fieldwork we recorded 8 species new to W-Hungary, including 3 species considered to be native to the region [Oenanthe banatica Heuff., Koeleria pyramidata (Lam.) P. Beauv., Polycnemum majus A. Braun.]. Almost all of the recorded species are regarded as indigenous plants, many of them has nature conservation importance, thus, their monitoring are highly advised. We found new localities of many species which of high importance for plant geography describing their current distribution. Most of the recorded species occur in natural or semi-natural habitats, but some taxa were found in synanthropic habitats and extensive arable lands.

  This article summarizes the recent occurrences of taxa of the C. brutia complex in Hungary. Formerly, C. hamulata was known from Hungary based on a specimen of uncertain origin from Vas County. The first confirmed record of the species date back to 2014, since then it has been found from from a total of 4 localities in streams in Western Transdanubia and along the Danube. The first detec­tion of C. brutia subsp. brutia was in 2016 in the Kunkápolnás marsh of the Hortobágy region, and since then the subspecies has been spreading in the area. The subsp. naftolsky was found in 2024 in a terres­trial form in a saltwater marsh in the Dél-Tiszántúl region. While C. hamulata is probably a native member of the Hungarian flora, the two subspecies of C. brutia may have colonised more recently, probably introduced by birds. Their colonisation may be related to the ongoing climate change, which has resulted in the introduction of plants from the Mediterranean region, often by natural means.

  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.

  The present study reports the occurrence data of 3 macrofungi and 47 vascular plant taxa, collected in Zalaegerszeg-Botfa between 2006 and 2017. These new data provide valuable additional information to the distribution map of the studied species. The spatial and abundance information of both protected and non-protected species can contribute to the future biodiversity monitoring activities in order to asses and mitigate the human impact upon natural plant communities and semi-natural habitats.
