Özet

Ranunculaceae Juss. comprises a diverse group of flowering plants with a broad global distribution. With over 2,500 species classified under 59 genera, this family is particularly notable for its adaptability to a wide range of ecological conditions, especially across the Northern Hemisphere. Among its members, the genus Ranunculus L. is cosmopolitan in distribution and currently includes approximately 1,761 accepted species worldwide. Ranunculus taxa are widely distributed both globally and within the flora of Turkey. According to the most recent records, 105 taxa of this genus are recognized in Turkey. Among these, 22 taxa (20,95 %) have been classified based on detailed morphological characteristics, including achene traits (such as achene and beak shape, pericarp structure, and indumentum), floral morphology (number and color of sepals and petals, as well as the presence of glossy petals), root structures (e.g.,tuberous roots), and fruit anatomy. Çanakkale Province, located in the Marmara Region of Turkey, occupies a biogeographically significant position at the intersection of the Euro-Siberian and Mediterranean phytogeographic zones.This transitional location contributes to the region’s high species richness and supports the presence of indicator species from both zones. In this study, Ranunculus species occurring naturally in Çanakkale were investigated. According to the records in Flora of Turkey and the East Aegean Islands, 18 Ranunculus species had previously been reported for the province. However, based on a comprehensive evaluation of specimens collected in previous years, new field collections,and herbarium materials housed in the Çanakkale Botanical Garden Herbarium (CBB), the presence of 26 taxa has been confirmed for the region. Two of these taxa are endemic, and the species are distributed across a variety of habitats. This study focuses on the habitat diversity and distributional features of the taxa.
