general taxon notes:
Dicranum japonicum has a wide distribution range in China. It shows considerable variation in plant habit and size. Type specimens of Dicranum longicylindricum, D. schensianum, D. japonicum var. yunnanense exhibit identical morphological concept we understand in China for D. japonicum.
