Rank ReasonsRare species of Southeastern Coastal Plain of the United States. Limited to a seepage or saturated wetland habitat on acidic peaty sand. This wetland plant is vulnerable or imperiled throughout much of its range, but may be apparently secure in Florida.
Range Extent CommentsEndemic to the Southeastern Coastal Plain, ranges from eastern North Carolina south to Florida and west to Mississippi (Weakley 1996). Kartesz, 1998, includes Virginia and Louisiana in this taxon's range, but it is now considered as falsely reported for Virginia (NatureServe central database as of November 2012) and is not documented in Louisiana in recent treatments (Flora of North America Editorial Committee 2000, Thomas and Allen 1993).
Occurrences CommentsConsidered to be vulnerable (S3) in Mississippi, vulnerable or imperiled (S2S3) in North Carolina, imperiled (S2) in South Carolina, Alabama, and probably imperiled (S2?) in Georgia (NatureServe central database as of November 2012). It is perhaps most abundant in Florida, where it is considered vulnerable or apparently secure S3S4 (NatureServe central database as of November 2012).
Threat Impact CommentsDams in streamheads to create aquaculture ponds for fish, and minor drainage associated with ongoing intensive pine management are both threats to this wetland plant which thrives in saturated peaty sands. Feral hog rooting is a threat to this plant in the coastal plain seepage habitat where it occurs (Engeman et al. 2007).
