The genus Verbascum (Scrophulariaceae, Lamiales), often referred to as Mullein, comprises about 360 species widely distributed in temperate regions in Europe, Africa, and Asia. The generic circumscriptions and location of the genus Verbascum is a challenge that has been the focus of debate among researchers. The genus Verbascum is still poorly understood and new species are described regularly. The taxonomy of Verbascum has been a source of contention, and it varies depending on the treatment.
