S. corrugata is an annual graminoid of the Poaceae family native to North America.[1]


S. corrugata is found along the southeastern coast of the United States from Texas to North Carolina[1] with disjunct populations in western Cuba.[2]



S. corrugata proliferates in pinelands and disturbed areas.[3] Specimens have been collected from open pineland, coastal hammocks, roadsides, banks of holding ponds, wooded old dune, sandy hardwood clearing, mixed forest, oak woods, longleaf pine sand ridge, wiregrass savanna, bluff by river, mangrove swamp, and open field.[4]

Seed dispersal

This species is thought to be dispersed by wind.[5]

Fire ecology

Populations of Setaria corrugata have been known to persist through repeated annual burning.[6][7]
