Bryophyta) in Russia
Arctoa (2012) 21:
207-220
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.
