For phytosociological study on the mantle community of Japan, a community system has been published by murakami (2004). But it has not been clear for most mantle communities in the tropical Southeast Asia. Reports on the mantle communities of the tropical mangrove forest area in Thailand (miyawaki et al., 1985) are valuable in that sense. However, the species composition tables of that report have not been published. The purpose of this report is to publish the species composition tables of mantle communities in the mangrove forest area of miyawaki et al. (1985). We also re-recorded, in English, the original description written in Japanese. Mantle communities in the mangrove forest area in Thailand were classified into two alliances. Finlaysonio-Derrilion trifoliatae (including two associations) was distributed in the front part of the mangrove forest area, and Clerodendro-Derrilion trifoliatae (including two associations and one community) was distributed in the rear part. The distribution patterns of both alliances nearly corresponded to two orders (nomen nudum) of mangroves forests.
