Rotala rotundifolia : ウィキペディア英語版 | Rotala rotundifolia
''Rotala rotundifolia'', the dwarf rotala, is a plant species often confused with ''Rotala indica''. It is sold in the aquarium trade, but is of uncertain status. It is a common weed in rice paddies and wet places in India, China, Taiwan, Thailand, Laos, and Vietnam, and has been introduced to the United States. ==Description== The emerse form has rounded leaves, the submerse leaves are narrow lanceolate. It is very variable dependent on light and environmental conditions. Under strong light, the leaves can become almost wine red. It has pale pink flowers. This plant can be differentiated from the closely related ''R. indica'' by the differences in the two species' inflorescences. ''R. rotundifolia'' bears groups of terminal inflorescence, while ''R. indica'' has solitary flowers on the axis of the leaves.
