  In this paper, we deal with threatened and/or legally protected bryophytes found in the shady, forested valleys of the Mecsek Mountains, which are rare in national and/or local terms. Taxip­hyllum den­sifolium, a rare moss in Europe has stable colonies with sporophytes in two valleys. This study is the first to describe the spore characteristics of this species. The previously considered unique and legally pro­tected Rhynchostegiella teneriffae is nowadays so widespread in the Mecsek that it can no longer be consi­dered a vulnerable species (VU) in Hungary. We present the first population of the legally pro­tected Nec­kera pennata in Tolna county, and we also report on the recent, unusual occurren­ce of the data-deficient (DD) Fossombronia wondraczekii. We also list new populations of three other endangered (EN) species, Blindiadelphus recurvatus, Palustriella commutata and Porella arboris-vitae. Several vulnerable (VU) taxa such as Blepharostoma trichophyllum, Porella cordaeana, Sciuro-hypnum flotowianum, Seligeria pusilla, as well as new occurrences of near threatened (NT) mosses such as Mic­roeurhynchium pumilum (with sporophytes), Phaeoceros carolinianus are documented. In addition, the data on Rhynchostegium rotundi­folium in Jakab Mountain, which has not been recorded for more than 50 years, is confirmed. The difficul­ties of differentiating Hygroamblystegium species are briefly discus­sed.

  The authors present the most important floristic data of Tolna and Baranya coun­ties, col­lected together or separately in the last 15 years, or observed by other data providers. In total, occur­rence data of 140 taxa are reported. Most of them are protected species in Hungary, but the list also includes rarer weeds (Ado­nis flammea, Althaea cannabina, Aphanes arvensis, Bunias orientalis, Legousia speculum-veneris, Vicia lutea) and adventive species (Helminthia echioides, Oxybaphus nyctagineus, Rubia tinctorum). Several species of phytogeographical importance were also found in the forest-steppe vegetation of the loess areas studied. Occurrence of Linaria biebersteinii should be highlighted. L. biebersteinii is a very rare species in the Transda­nubian region, and is no longer found in Europe west of this region. The occurrence of Himantoglossum adriaticum is a new contribution to the flora of the southern Transdanubian region.

  Here we evaluate the phytosociological characteristics of the turkey oak forests on sand (Fraxino orno-Quercetum cerridis) found at the northern foothills of the Vértes Hills, Hungary. Using the traditional Braun-Blanquet method, 20 vegetation samples were collected and compared with turkey oak forests growing in similar ecological situations in other parts of the country. The traditional and multivariate analyses showed that our samples were quite different from the compared forests, and only the forests in the Bakonyalja and the Pilis Mts showed some similarity with the compared forests. Our samples had the lowest proportion of Quercetea pubescentis-petraeae species among the compared forests, and the highest proportion of specialists (Corydalis pumila, Daphne laureola, Doronicum hungaricum, Lychnis coronaria, Physocaulis nodosus, Primula veris, Scutellaria columnae, Sorbus domestica and Veratrum nigrum). The samples were well separated from the compared forests and formed a distinct group.

  Poa remota, previously known in Hungary only from the northern part of the Hungarian Middle Range, was found in the Bakony Mountains, the southern part of the mountain range. The species was recorded at three localities in the central part of the „Öreg-Bakony” geographic unit, in the valley system of the „Fekete-séd” stream. Similar to other Central European observations, the species thrives in spring marsh habitats and alder swamp forests around the springs. Poa remota may be a relict species of a colder climate period in the Bakony Mts. Its occurrence is also important from a phytogeographical point of view, as this record slightly expands the local distribution limit southwards.

  This is the first in a series of papers by various authors presenting previously unpublished data relevant to the knowledge of alien vascular plants in Hungary. This paper deals with the families Pteridaceae, Brassicaceae, Plantaginaceae, Rosaceae, Ranunculaceae, Fabaceae and Poaceae. It includes new area records and distributional considerations for Cochlearia danica and Plantago coronopus spreading along Hungarian road-network as well as records of Panicum riparium from the Northern Hungarian Mountain range based on field work and herbarium revision. We note the importance of checking the data previously collected as P. capillare. Floristic data of two species not previously recorded in Hungary (Cardamine corymbosa, Ranunculus marginatus) and 3 sporadically occurring alien species (Aphanes australis, Lepidium didymum, Medicago arabica), from garden centres in the Debrecen area were published. A 7-year long survival of a population of Adiantum capillus-veneris in a traditional, abandoned well is also documented between 2017 and 2024. The paper reports that traffic infrastructure can facilitate the spread of Elymus elongatus along roads.
