Popis Stellaria ruderalis (Caryophyllaceae) is an annual herb of the S. media group, recently described in Central Europe and later discovered in other regions of the continent and beyond. Here, we provide novel data on its occurrence in the Caucasus Biodiversity Hotspot, where the species has not been collected since its description as new to science. Stellaria ruderalis was discovered at 14 sites in eastern and central Georgia (2022-2023) and northern Armenia (2023). It inhabited various ruderal habitats as well as deciduous and mixed forests. It is presumably a common component of the regional flora, although overlooked to date. Thus, its tentative IUCN classification is proposed here as Data Deficient (DD).
