Rosa oxyodon

There have been various hypotheses about its evolutionary origin. According to one, it originated from the ancestor of R. pendulina as it migrated from Central Asia to Europe; in that view, the rare R. donetzica would be another relict of this migration. There is a second hypothesis, based on genetic data, which proposes that R. oxyodon arose as a separate species out of a series of hybridisations between R. majalis and R. pendulina.[2]

The presence of Rosa oxyodon was reported in one place outside the Caucasus in 1967: in the Balkan Mountains of Bulgaria, specifically in a single location near Kozyata Stena.[3] Although in subsequent Bulgarian literature it has been assumed that the species is native to the country,[4][5] the case was re-examined by Polish botanist Jerzy Zieliński, who argued that the plants in question do not belong to R. oxyodon but instead represent a hybrid between R. pendulina and R. spinosissima.[1]
