The evergreen broad-leaved forests in Japan are distributed from Ryukyu -Islands to south and sea side districts of Northeast and west of the Tohoku district. The forests are called phytosociologically to Camellietea jabonicae Miyawaki et Ohba 1963 which is characterized by Camellia japonica, Castanopsis spp., Persea (Machilus) spp., Eurya japonica, evergreen Quercus (Cyclobalanopsis) spp. and other evergreen broad-leaved plants. In this report Camellietea japonicae was classified into 49 associations (8 newly described) and 7 communities, 5 alliances (3 are newly described) and 3 new orders according to the Braun-Blanquet's system of phytosociolgy. Twenty-two associations and one community belong to Quercion acuto-myrsinae-foliae al. nov,, Illicio-Quercetalia acutae ord. nov. Seven associations in this alliance arc newly described. They are Hydrangeo-Abietctum firmae, Pseudotsu-getum japonicae, Ophiopogono-Quercetum glaucae, Ilici-Quercetum glaueae, Lasiantho-Quercetum gilvae, Quercetum sessilifolio-myrsinaefoliae, Symploco-Ilicetum crenatae. Quercion acuto-myrsinaefoliae is distributed mainly in inland from Niigata Prefecture and Iwate Pref. to Yakushima in Kagoshima Pref. Seven associations and one community belong to Maeso japonicae-Castanopsion sieboldii al. nov., and are distributed hilly districts or alluvial plain along the coast from Miyagi Pref. and Aomori Pref. of the Tohoku (North-Honshu) to Kagoshima Pref. in Kyushu, Elaeo-carpctum elliptici among them, is newly descrived. Twelve associations and one community belong to Psychotrio-Castanopsion sieboldii Miyawaki, Fujiwara, Harada, Kusunoki et Okuda 1971, which is distributed in the district except on the elevated coral reef from islands of Yakushima and Tanegashima in Kagoshima Pref. to Iriomote Island in Okinawa Pref. of southern Japan. Five associations and one community belong to Rhaphiolepido-Quercion phylliraeoidis al. nov. which is distributed in the coastal cliff from Aomori Pref. and Miyagi Pref. (in North Honshu) to Okinawa Pref. These 3 alliances consistute Myrsino-Castanopsietalia sieboldii ord. nov. Five associations and one community belong to Psychotrio manilensis-Acerion oblongi Miyawaki et K. Suzuki 1974, Diospyro maritimae-Mallotetalia philippensis ord. nov. Psychotrio manilensis-Acerion oblongi is distributed on the elevated coral reef of Ryukyu-Islands. Camelietea japonicae will be larger class if it is able to compare with the vegetation the evergreen broad-leaved forests in Formosa and China.
