Chenia zanderi C.Feng & J.Kou (Pottiaceae, Musci), a new species from Yunnan, China

Abstract

A new species, Chenia zanderi C.Feng & J.Kou, from Xishan Forest Park in Yunnan Province, China is described and illustrated. Particularly distinctive features of the new species are the fragile stems and leaves fragile along their insertions, narrow leaves usually constricted near the middle, broadly rounded leaf apices with a long apiculus, large distal laminal cells with numerous solid and bifurcate papillae, a narrow groove on the distal ventral surface of the costa, and absence of a costal stereid band. A key for the species recognised in Chenia R.H.Zander is also provided.
