About this book

Language: Bilingual in English and Slovene

Helleborus (Helleborus L.) in Slovenia deals with the taxonomic classification of Helleborus, commonly known as hellebores, and its diversity and distribution in Slovenia. This genus comprises approximately 20 species of herbaceous or evergreen perennial flowering plants in the family Ranunculaceae. A separate chapter presents results on an analysis of the significance of basal leaves in determining hellebore species.
