Comments: Grassy vegetation on poorly drained, infertile sandy peat soils of the Florida Gulf coastal lowlands near the mouth of the Apalachicola River. Also in seepage bogs and savannas and, sparingly, on drier sites with longleaf pine and runner oaks. (Based on Ward 1979.)

Note: For many non-migratory species, occurrences are roughly equivalent to populations.
Estimated Number of Occurrences: 21 - 80
Comments: 33 occurrences verified since 1989, but some of these are sub-occurrences which are clustered into larger occurrences (EO data in the NatureServe central database as of April 2012).

United States
Rounded National Status Rank: N2 - Imperiled
Rounded Global Status Rank: G2 - Imperiled
Reasons: Endemic to small area of Florida Panhandle. Decreases in the quality and extent of appropriate habitat within this species' very limited range, and recent surveys within its range, suggest that the species is declining. The plants cannot withstand modern intensive forestry practices such as clear-cutting, chopping and tilling of the substrate, dense plantings of pine, and the subsequent exclusion of fire. Thirty-three occurrences have been verified since 1989, but some of these are sub-occurrences which are clustered into larger occurrences. Most of the occurrences are within the Apalachicola National Forest in Florida, but some are on nearby state conservation lands.
