Three remarkable additions of Orthotrichum species (Orthotrichaceae) to the moss flora of China

摘要

Three species of the narrowly constituted moss genus Orthotrichum are reported for the first time from China. Two of these, O. moravicum and O. scanicum, have been found in the Xinjiang Uyghur Autonomous Region. The third species, O. rogeri, was detected in Qinghai Province and at the same time this is the first discovery of it in Central Asia. Ecological and distributional details of the newly recorded species are provided and their local distribution in China is mapped. Considering the present records, Orthotrichum in a narrow sense consists of 30 species in China.
