Abstract
Orobancheingens is an endemic species from the Caucasus, especially the Greater Caucasus, parasitising on large Apiaceae (usually Heracleum). This species was misclassified over the years and little was known about its range and habitats. Here, we clarify the typification, as well as provide notes about the taxonomy of this species. Additionally, we presented distribution, habit and host range of O.ingens and morphological features that distinguish it from similar species.
