Abstract With approximately 25 endemic species, the genus Pyrus (pears) is highly diverse in Caucasus ecoregion. The majority of Caucasian pears inhabit xerophytic open woodlands or similar habitats, to which they display morphological adaptations, such as narrow leaves. other both and non‐Caucasian taxa, mainly mesophytic forests broad Using a representative taxon sampling from Caucasus, Europe Asia, we reconstruct phylogenetic relationships based on multiple plastid regions. We also...
