Paspalum setaceum is a species of grass known by several common names, including thin paspalum. It is native to the Americas, where it can be found in the eastern and central United States, Ontario in Canada,[1] Mexico, Central America, and the Caribbean.[2] It can be found in other areas of the world as an introduced, and often invasive, species, including many Pacific Islands.[3] It is a weed of lawns[3] and turf.[4]
This grass is a perennial with erect or prostrate stems that can exceed one meter in length. The flat leaf blades are hairless to slightly hairy. They vary in color. The panicle has up to 6 branches up to 17 centimeters long lined with small oval to rounded spikelets. There are several varieties of this species which can be distinguished in part by color.[1] Some authors do not recognize varieties.[5]
