Paspalum almum was probably introduced to North America as a forage species.
Its native range is Brazil, Paraguay, Uruguay, and eastern Argentina. It has not
been reported from Mexico or Central America. In the Flora region, it is
found along roadsides and in pastures of southeastern Texas and southern Louisiana.
