Data on the native vascular plant species of the Pannonian Region II. (6–22)
233–252Views:685In the second part of this article series, which provides data contributing to the knowledge of native plant species of the Pannonian Ecoregion, we address rare species – mostly legally protected in Hungary – belonging to the families Cephaloziaceae, Athyriaceae, Dryopteridaceae, Cystopteridaceae, Thelypteridaceae, Brassicaceae, Rosaceae, Elatinaceae, Apiaceae, Orobanchaceae, Liliaceae, and Orchidaceae. We report the current occurrence of Nowellia curvifolia in the Sub-Pannonian region of Slovenia. We present an exceptionally species-rich habitat for ferns (Athyrium filix-femina, Dryopteris carthusiana, D. dilatata, D. filix-mas, Gymnocarpium dryopteris, Polystichum aculeatum) from the ‘Borsodi ártér’ microregion. We provide data on the stands of Thelypteris palustris observed along the main irrigation canals of ‘Tiszántúl’ region. We publish new occurrence records contributing to the Hungarian distribution of Aethionema saxatile, Crataegus nigra, Elatine hungarica, Sium sisarum, Orobanche hederae, Himantoglossum adriaticum, Epipactis placentina, E. exilis, E. pseudopurpurata, and E. microphylla, as well as to the appearance of Helosciadium repens in urbanized environment. Gagea spathacea and G. bohemica are newly recorded for the Zemplén Mts; Epipactis nordeniorum and Epipogium aphyllum are new for the flora of the Mátra Mts; and Himantoglossum calcaratum is newly recorded for Hungary. We also present spontaneous establishment of several orchid species in the courtyard of a secondary school in Veszprém. Additionally, we report on the pollinating insects observed on the flowers of Sternbergia colchiciflora. Two previously misreported records are also corrected.

Contributions to the knowledge of biology and Hungarian distribution range of Orobanche reticulata
95-98Views:655Some new Hungarian occurrences of Orobanche reticulata Wallr. are discussed in this paper. On the Bér-hegy hill (Eastern Bakony Mts) the species was observed on a so far unknown host plant (Carduus hamulosus). Although the species usually flowers from May to July in Hungary, the observed individual was in full bloom in October, probably due to the extremely rainy year (2010). Another population of the species, found at Magyaralmás settlement in the foreground of the Vértes Hills, deserves attention because of its size. In early summer of 2020, individuals of O. reticulata appeared in a great quantity (several hundred ones) on a fallow land that was developed from a natural dry grassland having been ploughed in the previous year. In this case the local host plants were Carduus nutans subsp. leiophyllus and Carduus acanthoides. Some further records of the species from the Transdanubian Mts and the regions of Külső-Somogy and Mezőföld present new data in the Hungarian flora mapping program.
