Limnodea, with the common name Ozark grass,[2] is a genus of North American plants in the grass family.[3][4][5][6] The type species is Greenia arkansana Nutt..[3][7]

The only known species of the annual bunchgrass is Limnodea arkansana.
Distribution

Limnodea arkansana is native: to northeastern Mexico in Coahuila and Tamaulipas states; and to the South-Central/Midwestern and Southeastern United States, in Arkansas (including the Ozarks), Oklahoma, East Texas, Louisiana, Mississippi, Alabama, South Carolina, and the Florida Panhandle.[1][8][9][10][11]

It grows in dry and usually sandy soils, in prairie, open woodland, and river bank habitats; and in disturbed areas. Along the Gulf Coast it is found on upper beaches where shells accumulate, and on maritime shell mounds and middens.
