DRYOPTERIS x COMPLEXA NOTHOSUBSP. TRANSSILVANICA: A NEW HYBRID FROM THE CARPATHIANS (DRYOPTERIDACEAE, POLYPODIOPHYTINA)

摘要

During field studies in the Romanian Southern Carpathians and the Polish Western Carpathians, a new tetraploid fern hybrid was discovered. This taxon is described as Dryopteris x complexa nothosubsp. transsilvanica {Dryopteris affinis subsp. jesseniix D. filix-mas). The macroscopic identification is supported by flow cytometric and earlier cytological results.
