What distinguishes Brazilian elodea among submersed plants?

Brazilian elodea is distinctly characterized by its leaves, which are arranged in whorls and have minute teeth along their margins. This unique leaf structure sets Brazilian elodea apart from other submersed aquatic plants that may have different leaf arrangements or shapes. The whorled arrangement allows for effective light capture underwater, which is crucial for its growth.

The presence of female flowers only, the production of tubers, or swollen leaf stalks are characteristics that might apply to other aquatic plants, but they do not specifically pertain to Brazilian elodea. The plant's whorled leaves with minute teeth is the most identifying feature that helps in its proper identification in aquatic environments. Understanding these distinctions is critical for effective management and control in aquatic systems.
