About

Callitriche stagnalis is an aquatic species commonly utilized for oxygenation in pond environments. It features spoon-shaped submerged leaves that reach lengths of up to 2cm, alongside rosettes of wider floating foliage. The stems typically anchor into damp soil, creating a dense mat. The flowers are inconspicuous.
