ABSTRACT. The genus Leptopterigynandrum in Russia includes 6 species (L. austro-alpinum Müll. Hal., L. decolor (Mitt.) Fleisch., L. incurvatum Broth., L. piliferum S. He, L. subintegrum (Mitt.) Broth. and L. tenellum Broth.) occurring in South Siberia from Transbaikalia to the Altai, in the Suntar-Khayata Range in Yakutia and in Chukotka. Most species can be separated by unique substitutions in nuclear ITS sequences, excepting L. decolor and L. tenellum represented by the same haplotype. The familial placement of Leptopterigynandrum is discussed and the new family Taxiphyllaceae is described to accomodate this genus together with Taxiphyllum, Hondaella, as well as with Glossadelphus ogatae. The genus Taxiphyllum is lectotypified with Taxiphyllum taxirameum.
