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 dilatatum is native to Brazil and Argentina. It is now well established in the Flora region, generally as a weed in waste places. It is also used as a turf grass. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
