Abstract

To clarify the floristic composition of paddy field communities in tropical Asia, phytosociological research was conducted in Yunnan Province of China. Relevés were then compared with relevés in Japan, South Korea and North Korea in East Asia, and relevés on the tropical islands of Hainan, China, and Sumatra, Indonesia. The results showed that the relevés in Yunnan Province and on Hainan Island, as well as a few relevés in Okinawa Prefecture could be described by the new association Ludwigio adscendentis - Monochorietum vaginalis. This association was divided into 5 subassociation. The association is belonged to Oryzo - Echinochloion oryzoidis, Cypero - Echinochloetalia oryzoidis, Oryzetea sativae as upper vegetation unit.
