Spartina bakeri
Spartina spartinae
Spartina bakeri grows on sandy maritime beaches and other salt water sites in the southeastern coastal states and on the shores of inland, freshwater lakes in Florida. Its inflorescence is similar to that of S. patens, but the branches of S. patens usually diverge from the rachises at maturity, whereas those of S. bakeri remain appressed. Spartina bakeri is distinct from most other species of Spartina in North America in forming dense clumps and in being able to grow in freshwater habitats.

Spartina spartinae grows from the Gulf coast through Mexico to Costa Rica in North America and, in South America, in Paraguay and northern Argentina. In the United States, it grows in sandy beaches, roadsides, ditches, wet meadows, and arid pastures near the coast, the most inland collection being 60 miles from the coast. In other parts of its range it sometimes grows well inland in saline soils where Pinus palustris (longleaf pine) is dominant or co-dominant.
