  This study presents the current distribution of narrow small-reed (Calamagrostis stricta (Timm) Koeler) in the southern part of Nyírség (E Hungary). Beyond the efforts to confirm previously known occurrences, a high number of potential habitats were surveyed. Field work was carried out from late autumn to early spring taking advantage of the better perceptibility of dry foliage. The species was detected in 43 localities inside the boundary of 15 settlements, which considerably exceeded our expectations. Although most of the populations were quite small, in some cases their extent reached over 1000 m².  Populations around the settlements of Penészlek, Fülöp and Nyírábrány were the most frequent and the largest in size. The endangered status of the species is caused by the insufficient water supply of suitable habitats in the region. Besides habitat change, desiccation can also amplify the effect of anthropogenic disturbances (e.g. ploughing, fishpond development), which poses a further threat to populations.

  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.

  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.

  We report the occurrence data of 45 vascular plant taxa collected at various localities in Hungary (Duna–Tisza Interfluve, Tiszántúl and South Transdanubia) during floristic, vegetation and ecological field surveys mostly between 2013 and 2016. Many of these plants are included in the ’Red list of the vascular flora of Hungary’ (e.g. Astragalus dasyanthus, Erodium ciconium and Lotus angustissimus). We primarily focused on the occurrence of rare plants (e.g. Apium repens, Epipactis bugacensis and Trifolium strictum), plants that appeared in unexpected places (e.g. Medicago arabica, Polypodium vulgare and Polystichum setiferum) or have a phyto-geographic importance (e.g. Piptatherum virescens, Ranunculus psilostachys and Tamus communis).
