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.
