About Paspalum distichum L.
Paspalum distichum L. is a species of grass. It has several common names: knotgrass, water finger-grass, couch paspalum, eternity grass, gingergrass, and Thompson grass. Its native range is unclear, as it has already been established across most continents for a long time, and it is definitely an introduced species in most regions. Its native range likely includes parts of tropical America. This is a perennial grass that grows in clumps and spreads through rhizomes and stolons. It grows either decumbent or erect, reaching a maximum height of around 60 centimeters. Its inflorescence is usually split into two branches lined with spikelets. Paspalum distichum serves as a food source for several bird species, including the long-tailed widowbird.
