  The phytosociological characteristics of the oak woods on the Szentendre Island were first studied 70 years ago. We conducted a follow-up study to determine the phytosociological relationships of theses woods and assess their possible changes over time. We found that these woods are most similar in their phytosociological characteristics to the closed pedunculate oak forests occurring in the high floodplain in the Szigetköz area (Melico nutantis-Quercetum roboris) along the Danube. Our results also showed a marked increase in the proportion of natural weeds, introduced species and invasive aliens in the studied woods.

  This paper presents occurrence data of 169 taxa from the Lengyel–Hőgyész Natura 2000 site (HUDD20026) which is on the southern part of Tolna Hills, SW Hungary. Data were collected during three years (2015, 2016, 2017), on different sites annually. The presented data contribute to the distribution dataset of Atlas florae Hungariae. Regionally rare or sporadic species (e.g. Asplenium scolopendrium, Asplenium trichomanes, Polystichum setiferum, Doronicum hungaricum, Paris quadrifolia, Scilla vindobonensis) are enumerated. Presence of Epipactis leptochila subsp. neglecta and Platanthera chlorantha were not registered from this site before. Subspecies of Carex divulsa are also studied on this site – distribution of these infraspecific taxa have not been mapped recently in Hungary.
