The branching stems of the plant grow to about 40 cm 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 cm 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.
