By referring to a few healing herbs (belladonna, yarrow), using as a reference point both the scientific (scholarly) denominative and the folk (naive) models, we underline the dividing line between scientific thinking and empirical thinking. The scientific name is intended to stop possible confusions that arise when two different plants have identical regional names. Even if most scientific names, related to phytonyms, are of Latin origin, we note that there are also exceptions (for example, a term of Greek origin and another of Roman origin – Atropa belladonna – or a term that reminds us of the legendary Achilles, and the other of Latin origin – Achillea millefolium). The regional names, on the one hand being multiple, on the other hand being diverse, impose a nomenclature that enhances the identified symbol (phytomorph, anthropomorph, avimorph, zoomorph, etc.), depending on the ethnographic area of the country. By referring to the aforementioned healing herbs, we discover that the binary scientific name - regional name reveals a linguistically captivating plant universe.

"The paper aims to highlight the discrepancy between the scientific term and the regional names given to the oak. Starting from the scientific and folkloric denominative model, we discover a complex dendromorphic symbol that can be analysed from an interdisciplinary perspective (art, ethnology, history, linguistics, literature, medicine, mythology, religion, etc.). The onomastic nuclei (toponymy, anthroponomy) and the potentially identified semantic isotopies enhance the complexity of the topic."
