The climatic climax forest vegetation in the eastern part of Kochi Prefecture was investigated. In this district the average annual temperature is 16.9℃, and the annual rainfall amounts to 3451.8 mm. Therefore the evergreen broad-leaved forest is found as a climatic climax. The results of the vegetational survey of seven residual stands shown in Fig. 1 are given in Table 2. Though the dominant species in the 1st tree layer is Shiia cuspidata and not Sh. sieboldii, it is considered that these evergreen forests should be included in the Rapanaeto-Shiietum sieboldii Suz.-Tok. which is distributed all over southwestern Honshu, Shikoku, and Kyushu. In this district this association is characterized by such plants as Shiia cuspidata, Meliosma rigida, Elaeocarpus japonicus, Distyrium racemosum, Randia cochinchinensis, Mephitidia satsumensis, M. japonica, Cleyera ochnacea, Rapanaea neriifolia, Ilex integra, Bobua theophrastaefolia, B. prunifolia, B. lancifolia, B. glauca, Alpinia japonica, Rumohra aristata var. pseudoaristata, Dryopteris erythrosora, D. fuscipes, etc.
