Taxonomic notes
Description
Distribution
It is found as north as New Jersey, south to Florida, and west to Texas (Weakley 2015).
Ecology
Habitat
It occurs in frequently burned upland longleaf pine-wiregrass communities, longleaf and shortleaf pine-oak hickory communities, loblolly pine plantations on Ultisols, the higher parts of pine flatwoods, as well as edges of unburned hardwood foresets (Brockway et al. 1997: FSU Herbarium). Soil conditions range from wet to very well drained and sand to loamy sands. It is found in dry sandy soils of sandhill habitats and fields (Weakley 2015). It can also be found in human disturbed areas such as recreational areas, roadsides, longleaf pine clearings, dry sandy soil of campsites (FSU Herbarium). This species grows in large clumps together (FSU Herbarium).
Phenology
It flowers from August to October and has been seen fruiting from October to November (Weakley 2015, FSU Herbarium).
Seed dispersal
Seed bank and germination
Fire ecology
Burning during the growing season is thought to primarily stimulate seed production by important grass species in longleaf pine wiregrass communities, possibly including Aristids lanosa (Biswell and Lemon, 1943; Streng et. al, 1993 cited by Brockway et al 1997). However, burning during winter is also beneficial.
Pollination
Use by animals
Diseases and parasites
