Rotala ramosior is a species of flowering plant in the loosestrife family known by the common name lowland rotala. This aquatic or semi-aquatic plant is native to North America, where it grows in water bodies such as lakes, streams, and irrigation ditches. The branching stems of the plant grow up to about 40 centimeters long. Leaves are decussate, arranged oppositely in perpendicular pairs along the stems. The leaves are linear to lance-shaped to oval and up to 5 centimeters long. Flowers occur singly in leaf axils. Each has triangular sepals with long, narrow appendages and usually four tiny white petals in shades of pink to white.
This plant is sometimes grown in aquaria.
