Rank Reasons
Agalinis filicaulis is found in longleaf pine savannahs, bogs and prairies in the southeastern United States which are threatened by habitat conversion and fire suppression. This species can be locally common, however, current surveys are needed to better estimate overall population size and viability.
Range Extent Comments
Agalinis filicaulis is endemic to the southeastern United States, and known from southern Georgia, south to central Florida and through the Panhandle, west to Alabama, to southwestern Louisiana (Weakley 2020).
Occurrences Comments
There are at least 60 documented occurrences of this species (NatureServe 2021).
Threat Impact Comments
