Distribution
Ecology
Habitat
P. aspera is distributed across southern Georgia and northern Florida (Gowe and Brewer 2005)and is commonly found in Florida sandhill community (Downer-MR_2012_MSThesis.) Habitats documented include longleaf wiregrass sandhills, deep sand banks along hardwood hammocks, open pinewoods, longleaf pine/turkey oaks, scrub oak barrens, longleaf pine savannas, sand pine-evergreen oak scrubs, a high bluff overlooking creek, and chestnut oak woods (FSU Herbarium). In disturbed areas it grows in beds of old railroads, roadsides with bahia grass, a clearing of mixed pine-hardwood stand, harrowed areas, bordering fields, and on golf course edges alongside broomsage (FSU Herbarium). Soil types include sand, dry loamy sand, dry clayey sand, gray sand, wet soil, dry sand-clay bank, loam soil, red clay bank and gravelly-clay (FSU Herbarium).
Associated species include Pityopsis flexuosa, Pinus palustris, Aristida stricta, Chrysopsis latisquamea, Chrysopsis gossypina Quercus, Paronychia, bahia grass, Haplopappus divaricatus, Eupatorium pinnatifidum, Lechea, Diodia teres, Dicanthelium, Lespedeza hirta, Polygonella gracilis, Vaccinium arboreum, sandpine, Microcephala, Liatris, Panicum, Leptoloma cognata, Phoebanthus, Scleria ciliata, Helianthus microcephalus, Helianthus atrorubens, Silphium compositum, Eupatorium, Heterotheca latifolia and chestnut oak (FSU Herbarium).
Occurs in areas with an estimated pre-settlement fire-return interval of 1-3 years (Gowe and Brewer 2005).
