Flora of an irrigated paddy field in Naganuki, Hadano City, was surveyed from April 2006 to April 2007. One hundred thirty-seven species from 48 families were identified in the irrigated paddy field. Representatives of plants species examined in the irrigated paddy field were Stellaria alsine var. undlata, Potentilla sundaica var. robusta, Arthrxon hispides, Juncus effsus van decipiens, Oenathe javanica, Monochoria vaginalis, Ludwigia epiloides, Ranunculs sceleratus, Rotala indica var. uliginosa, Cardamine flexuosa var. latifolia and Persicaria thubergii. Oenathe javanica, Cardamine flexuosa van latifolia and Persicaria thubergii are widely distributed in different habitats such as wet paddy fields and natural drainage canals. An endangered species, Ottelia alismoides, was also observed in the wet paddy field. The traditional irrigated paddy field in the study site supported diverse plant species including aquatic, wetland and land plants. To conserve the diverse flora of areas such as the study site, the continuation of traditional land management is necessary.
