 note = {application/pdf, application/pdf, postprint, A phytosociological study was conducted on evergreen broad-leaved forests in the Chichibu district of central Honshu. Four associations and one community were determined: a Polysticho-Perseetum thunbergii, an Ardisio-Castanopsietum sieboldii, a Quercetum myrsinaefoliae, a Sakakio-Cyclobalanopsietum and a Quercus glauca community. These vegetation units occur in different horizontal habitats and precipitation areas. Evergreen broad-leaved forests in this district, except the Ardisio-Castanopsietum sieboldii, contain summergreen species, about 70% as many as the number of evergreen species growing there. In the Ardisio -Castanopsietum sieboldii, however, the number of summergreen plants is smaller, cpmprising less than 40% of the number of evergreen species. The life-form spectrum of the Ardisio-Castanopsietum sieboldii is similar to that of evergreen broad-leaved forests found near the sea.},
