  The origin of a more than 150 years old herbarium specimen of Calla palustris L. stored in JPU is reconsidered in this study. According to the information on its label, the specimen was collected in 1856 at Lake Velence, close to Székesfehérvár city (central Hungary). Some Hungarian botanists are skeptical about the authenticity of this record. Based on the current occurrences of some remarkable swamp species (e.g. Carex pseudocyperus, Liparis loeselii, Sphagnum spp.) and habitat types (e.g. willow carrs and swamp forests) at the lake, as well as the habitat preference of bog arum, there is no reason to question the former occurrence of the species here or even in other Hungarian localities. The content and accuracy of the examined voucher meet the expectations of floristic data. However, in the absence of recent data the species can be considered extinct from Hungary.

  In the third part of the article series providing data on the knowledge of native plant spe­cies in the Pannonian Ecoregion, we present new localities for Anchusa ochroleuca, Carpesium abrota­noides, Leucanthemella serotina, and Carex fritschii.

  • Anchusa ochroleuca was known only from one place in Hungary in the last decades. In the spring of 2025, approximately 400 individuals of Anchusa ochroleuca were found near to Rád, in the Kosd Hills region. Its habitat is typic, individuals were found in an opened, slopey loess grassland (Salvinio nem­orosae-Festucetum rupicolae). However, great part of the habitat is perturbated, other rare steppe-meadow species were found parallelly with an almost complete absence of forest-steppe species and species with a border-related character. Habitat of Anchusa ochroleuca is endangered mostly by per­turbation of nutrients came from adjacent arable field and populations of wild boar and deer species, but also by plant invasions and spreading of shrubs.
  • Carpesium abrotanoides was previously known in Hungary only from Southern Transdanubia and the southern part of the Danube–Tisza Interfluve. A population of the species consisting of several hun­dred individuals was discovered in the fen-woods around Ócsa, followed by the detection of a second, smaller population nearby in 2025. The populations occur in young and middle-aged fen-woods, where abrotanoides appeared on the drying peat surface along with disturbance-tolerant, short-lived plants. Similarly, two small populations of Leucanthemella serotina were found in the fen wood­land habitat complex of Ócsa. Decades ago, populations of this species were recorded here, but its oc­currence has not been assessed since then.
  • In Hungary, Carex fritschii was previously known only from Transdanubia. In 2012 and 2022, the spe­cies was discovered in the Central Ipoly Valley, far from its known national distribution limit. We de­scribe the sand steppe meadows of unique composition and their vegetation mosaics, and list new floristic data from them. We also describe the most important factors relating vegetation and land use history in the background of Carex fritschii The most significant floristic findings are Ag­rimonia procera, Danthonia alpina, Festuca rubra, Hypochoeris maculata, Potentilla alba, Ranunculus illyricus, Scorzonera purpurea, Thesium ramosum and Viola ambigua.

  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.
