Új páfrányfajok és hibridek a Hargita flórájában
The Hargitha Mountains was created by intensive volcanic activity from the Paleogene to the Quaternary era, thus this is the youngest volcanic mountains of not only the Eastern Carpathians, but the whole Carpatho-Pannonian Region as well. The various geologic, hydrologic and climatic influences combined with altitude differences (ranging from 550 to 1800 m asl.) gave way to a diversified flora and vegetation.55 pteridophyte taxa were identified on field excursions. Among them, 6 were not reported from the Hargitha Mountains before, namely: Polystichum × luerssenii, Dryopteris affinis, D. expansa, D. remota, D. × sarvelae and D. × deweveri. The last two taxa is not mentioned in the Euro+Med PlantBase database, thus seems to be new to the flora of Romania. This paper focuses on the description of the abovementioned six taxa.
