|Natural range of Eustachys floridana from USDA NRCS Plants Database.|
Synonyms: Chloris floridana (Chapman) Wood.
E. floridana is found in Alabama, Georgia, and Florida. Within this range, it is found from eastern Georgia south to central peninsular Florida and west to the western panhandle of Florida and southern Alabama.
E. floridana proliferates in sandhills and pine flatwoods, as well as pine rocklands and marl prairies. Specimens have been collected from open oak woods, open longleaf sandhill, flatwoods, and wiregrass sandhill communities. It is considered an indicator species of the north Florida longleaf woodlands habitat. Thinning the overstory has a negative effect on the abundance of E. floridana but this species was found to persist with clearcutting disturbance.
Associated species include Pinus palustris, Pinus taeda, Aristida sp., Croptilion sp., Liatris sp., Eupatorium sp., and Tridens sp.
Eustachys floridana is an indicator species for the North Florida Longleaf Woodlands community type as described in Carr et al. (2010).
E. floridana is a perennial herb to 1 m tall; raceme rachis wingless, triangular, fertile lemma pale or gray. 
This species is thought to be dispersed by wind. 
This species occurs in habitats that are fire-dependent.
