The investigation was conducted on Mt. Daisen, an extinct volcano in Tottori Prefecture, Lat. 35゜ 20'N., 133゜30'E. (Fig.1), where there occurs a characteristic plant community decidedly dominated by the dwarf coniferous tree, Taxus cuspidata var. nana REHD., which in rare cases is accompanied by Alnus hirsuta TURCZ., Sorbus Commixta HBDL. and Salix vulpina ANDERS. The epiphytic bryophyte community in this dwarf coniferous forest is composed mainly of Orthodicranum hakkodense Lesquereuxia robusta and Ptilidium pulcherrimum. Orthodicranum hakkodense and Lesquereuxia robusta are the dominant species in the crown layer of this community. Rhacomitrium canescens, which grows usually on rocks and soils, characteristically develops only on trees exposed to strong winds and laden with the granules of sandy soil picked up from eroded and barren places. It is significant that these species are absent in all other layers of the community, being restricted to the crown layer. Ptilidium pulcherrimum, new to the bryophyte flora of Mt. Daisen, is dominant to a considerable degree on the tree trunks, while lsothecium subdiversiforme and Dolichomitriopsis diversiformis grow only at the base of the trunk.
