Didymodon schensianus

Didymodon (Barbula) schensianus was described from China, Shaanxi Province in 1896 and considered as its endemic, known from few localities. Furthermore, Li et al. (2001) included it into synonymy of D. vinealis . However, Jiménez et al. (2024) have shown that it is a species of its own, which has a wider distribution, being common in Japan (Honshu, Kyushu), found in Taiwan and Philippines. These authors compare D. schensianus with the most similar D. hengduanensis which was already found in Russia. However, our search in herbarium collections from the Russian Far East did not return any results, and no sequences similar to the GenBank accessions of D. schensianus were obtained.
