SUMMARY
morphometric analysis of Slovenian material belonging to Hordeum murinum ssp. leporinum and type subspecies confirmed some of already reported distinguishing characters, but majority of them were not measured precisely before. After revision of herbarium material based on results, about 9% of sheets are still somehow »intermediate«, H. murinum ssp. leporinum is more common in Submediterranean part with some scaterred populations in continental Slovenia and the type subspecies occurr all over Slovenia in lowland ruderal places. Detailed determination key is provided based on results.
