  Verges have considerable importance to preserve diversity in arable landscape. The modernized railway embankments are a great surface to the spread of native pioneer or adventive (invasive) plant species. The new data are about the flora of railway embankments mainly from Tiszántúl region. I present some species found on railway verges (e.g. Equisetum ×moorei, Equisetum ramosissimum, Lycopsis arvensis, Euphorbia maculata, Lepidium densiflorum Tragus racemosus, Vulpia myuros). An especially important new data is the refinding of Galium humifusum in Hungary. Locally non-native and adventive species can use the blanketing materials (sand or gravel) of railway embankments as dispersal corridor and colonize them. The railwayside habitats could contribute to the conservation of rare native pioneer species.

  The current paper is the 8^th in the series aiming to contribute with new distribution data to the maps published quite recently in Atlas Florae Hungariae. Distribution data of 539 plant taxa from 157 flora mapping units is presented in this study, most of them are located in the western half of the country. As a result of systematic surveys, more than 190 new species were found in a single flora mapping quadrat. In another survey along some asphalted roadsides Puccinellia distans was found as a new species for 68 flora mapping grid units. All these indicate the necessity of further systematic research and publication of floristic results in papers like the “Contributions…” series. Most of the enumerated taxa are frequent, treated usually as weeds, but some of them are sparse and scattered or rare in Hungary (e.g. Nigella arvensis, Vaccaria hispanica, Rumex pulcher, Urtica urens), and in some cases they are legally protected plants in Hungary (e.g. Asplenium adiantum-nigrum, Dryopteris affinis, Gymnocarpium dryopteris and Huperzia selago). We also listed some casual alien plants and naturalized species that were not mentioned in the last neophyte list of Hungary (e.g. Acer cissifolium, Cyperus alternifolius, Gaillardia aristata, Galanthus elwesii). In the Outlook we pointed out the insufficient survey of some synanthropic (urban) habitat types in Hungary, like verges, gardens and flowerbeds that can be the hotbed of established species or can serve as stepping stones for potential invaders.

  Himantoglossum adriaticum H. Baumann is a Natura 2000, CITES species and strictly protected plant in Hungary. During my field work (1992–2016) I realized some similarities in the characteristics of the habitats where the plant grows, so I wanted to know the land use history of the areas in question. The H. adriaticum population of Keszthely Hills was studied the longest time. There were annually 7–78 inflorescences between 1992–2016. Recently two further localities were found in Keszthely Hills. They grow in the edges of grasses used earlier as pasture, minor roadside verges and nearby abandoned vineyards. The largest population can be found in Sümeg region, majority of the individuals are along a paved road. Among the estimated 1000–2000 individuals 10 (2012) to 214 (2014) flowered. In Kőszeg, the lizard orchid grows in abandoned vineyards and in old traditional orchards. The maximum number of inflorescences was 165 (2016). In Bakony Hills its habitats are vineyards and orchards abandoned approximately 50 years ago. The size of H. adriaticum population here is nearly the same as in the Keszthely Hills. Four out of the five populations are growing on sites used as vineyard or orchard already in the years of the First Military Survey. The only exception is the population of Sümeg region. Every habitat is threatened by spontaneous forestation, but the species is able to find new habitats, so we do not worry about the drastic decline of the individuals in Hungary.
