We have 6 species of paspalum, but only 2 or 3 are troublesome and these are located mostly in southern Jersey. Field paspalum (Paspalum laeve), is the most widespread one and seems to prefer moist, sandy areas. Florida paspalum (P. floridanum var glabratum), is located in Cape May County. These seem to be problems in turf areas.
