Discussion | Paspalum notatum is native from Mexico through the Caribbean and Central America to Brazil and northern Argentina. It was introduced to the United States for forage, turf, and erosion control. It is now established, generally being found in disturbed areas and at the edges of forests in the southeastern United States. Paspalum notatum is sometimes treated as having distinct varieties. They are not recognized here because the variation among them is continuous. A number of cultivars have been developed for use as turf grasses; among these cultivars are 'Common Bahiagrass', 'Pensacola Bahiagrass', and 'Argentine Bahiagrass'.

Paspalum urvillei has been introduced to the United States from South America. In the Flora region it grows in disturbed, moist to wet areas, primarily in the southeastern United States. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
