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. The species epithet palustris is Latin for "of the marsh" and indicates its common habitat.[3] Chromosome number was confirmed as 2n = 24 in Japan.[4] References1. ^{{cite news | first = Simon | last = Hadlington | title = Science & nature: Invasion of the Lakes ; Eighty years ago, a naturalist surveyed the Lake District's aquatic plant life.
