Bai, X.-L., D.-P. Zhao, B.C. Tan, E.A. Ignatova & M.S. Ignatov. Mosses of Picea crassifolia forest in Helanshan (Ningxia, China)
Arctoa (2011) 20: 81-86
An unusual xerophytic composition of mosses in Qinghai spruce (Picea crassifolia) forest in Helanshan is discussed. Abietinella abietina, Hypnum vaucheri, Pseudostereodon procerrimus, Trachycystis ussuriensis and Timmia bavarica are dominants of the moss layer under dense canopy of spruce. This composition is somewhat similar to that in P. schrenkiana forest in Middle Asia.
