Habitats of waterhyacinth [Eichhornia crassipes (Mart.) Solms] in Chikugo River and its tributaries of Kyushu were investigated on October, 1978. Waterhyacinth plants in the lower stream of the River were mainly those which flowed down from its middle one or creeks of the paddy area through tributaries. In the middle stream, large populations of the plant were found especially around Kurume-city to the junction with Kose River. Among tributaries of the middle stream of Chikugo River, Homan, Shianbashi, Kose, Koishibaru and Katsura Rivers were infested with waterhyacinth. In the upper stream above the junction with Katsura River, there grew no plant of waterhyacinth.
