Abstract
Bryophyte flora of the Daiyûzan Saijô-ji forest, Kanagawa, Japan is studied. Among 950 specimens collected for this study, 178 species, 7 subspecies, and 8 varieties are recognized. Taxa of phytogeographic interest include Fissidens geppii, F. protonemaecola, Pyrrhobryum latifolium, Drepanolejeunea erecta, and D. vesiculosa. The bryophyte flora at the Daiyûzan Saijô-ji is numerous and diverse compared with other places around the survey area. The present investigation suggests that the decline of the large Cryptomeria japonica trees would have made the forest floor brighter, and montane species which are vulnerable to sunlight and drought could have decreased and ruderal species increased.
