Description

It is an annual (Hall 1993).

Distribution

It is infrequent in all of Florida. Found from: west to Mississippi and north to Pennsylvania (Hall 1993). It's found within the coastal plain, from Delaware to the Florida Keys, westward to southeastern Louisiana (Godfrey 1981).

Ecology

Habitat

It occurs in frequently burned upland pine communities (Ultisols), flatwoods (Spodosols), and wet meadows, savannas, and seepage slopes (pitcher plant bogs) including peaty areas (Histosols). It is also occurs on shallow calcareous soils of limestone glades of northern Florida and oolitic limerock of slash pine rocklands in sothern Florida (FSU Herbarium). It occurs in primarily high light areas maintained by fire or edaphic conditions but also partial shade adjacent to open areas (FSU Herbarium). It is tolerant of competition with dense grass and often occurs in conjuction in areas dominated by bunch grasses and sedges (FSU Herbarium). It seems to be limited to native pine and wet prairie communities with minimal soil disturbance, although it can occur on roadsides (FSU Herbarium).Is found in pine savannas, flatwoods, and bog margins (Wunderlin and Hansen 2003). It is also found in seasonally wet pine savannas and flatwoods, hillside bogs in pinelands, in shallow soil on oolitic limestone in pinelands (Godfrey 1981).

Phenology

It flowers in March and August through November (FSU Herbarium). This species also starts to fruit September through October (FSU Herbarium).

Fire ecology

It does well in frequently burned old growth longleaf pine and wiregrass savannas (FSU Herbarium).
