Zannichellia palustris, the horned pondweed, is a plant found in fresh to brackish waters in the United States (especially in the Chesapeake Bay), Europe, Asia, Australasia, and South America. It is recognizable by its long, thread-like leaves and "stringy" appearance. Its roots are long and tendril-like, and its seeds bear a distinctive horned shape, hence the common name.
