Taxonomic Notes
Synonyms: Chloris floridana (Chapman) Wood.[3]
Varieties: none.[3]
Description
E. floridana is a perennial graminoid of the Poaceae family native to North America.[1] It generally reaches heights of between 4 and 10 dm tall with slender stems.[4]
Distribution
E. floridana is found in Alabama, Georgia, and Florida.[1] 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.[2]
Ecology
Habitat
E. floridana proliferates in sandhills and pine flatwoods[2], as well as pine rocklands and marl prairies.[5] Specimens have been collected from open oak woods, open longleaf sandhill, flatwoods, and wiregrass sandhill communities.[6] It is considered an indicator species of the north Florida longleaf woodlands habitat.[7] Thinning the overstory has a negative effect on the abundance of E. floridana but this species was found to persist with clearcutting disturbance.[8]
Associated species include Pinus palustris, Pinus taeda, Aristida sp., Croptilion sp., Liatris sp., Eupatorium sp., and Tridens sp.[6]
Eustachys floridana is an indicator species for the North Florida Longleaf Woodlands community type as described in Carr et al. (2010).[9]
Phenology
E. floridana is a perennial herb to 1 m tall; raceme rachis wingless, triangular, fertile lemma pale or gray. [5]
Seed dispersal
This species is thought to be dispersed by wind. [10]
Fire ecology
This species occurs in habitats that are fire-dependent.[7]
