Adatok a Pannon Ökorégió őshonos növényfajainak ismeretéhez II. (6–22)

In 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.
