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 also long and tendril-like, and its seeds bear a distinctive horned shape, hence the common name. Chromosome number was confirmed as 2n = 24 in Japan.
