Rola słowników łaciny średniowiecznej w badaniach nad słowiańskimi nazwami roślin

The aim of the article is to indicate how many Slavic dialectal plant names have Latin or even Greek origin. Conducting such research, linguists dealing with the history and origin of these names cannot be satisfied with solely Slavic sources and dictionaries, but should extend their research to Latin and Greek botanical names, both ancient and medieval, using obviously suitable sources in this domain. Medieval Latin dictionaries play a prominent role in such investigations providing ordered collections of plant names originating from ancient Latin documents, which otherwise remain largely inaccessible to slavists.
