Notes on the taxonomy and geography of the genus Dontostemon Andrzejowski ex C. A. Meyer (Brassicaceae) are given. Torularia sergievskiana Polozhij is reduced to synonymy of D. pinnatifidus (Willdenow) Al-Shehbaz & H. Ohba, and D. glandulosus (Karelin & Kirilov) O. E. Schulz is excluded from the flora of Russia. A new subspecies, D. senilis Maximowicz subsp. gubanovii D. German (northwestern Mongolia), is described. Dontostemon intermedius Voroschilov is recognized as an independent species instead of a synonym of D. dentatus (Bunge) Ledebour.
