Zannichellia palustris

Zannichellia palustris, the horned pondweed,[1] is a plant found in fresh to brackish waters in the United States (especially in the Chesapeake Bay),[2] 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. The species epithet palustris is Latin for "of the marsh" and indicates its common habitat.[3] A diploid, its chromosome number was confirmed as 2n = 24.[4]
