Phenotypic variation of Epipactis helleborine x E. atrorubens hybrids in anthropogenic conditions

Wojciech Adamowski

Abstract


Hybrid index has revealed the hybrid nature of helleborine populations growing on disturbed habitats in Białowieża Forest and its western foreland. An analysis of eight traits has revealed that hybrids are morphologically more similar to E. helleborine. Hybrids differ from the typical E. helleborine first of all by: a very pubescent inflorescence axis, a considerable length of the subinflorescence internode. Also the range of phenotypical variation in these populations is shown.
