Andropogon longiberbis is a perennial bunch grass whose erect stems grow between 50 - 150 cm tall and are smooth, round, and taper to the ends. The leaf blades exist mostly around the base of the plant stems and are flat and linear, 2 - 10 mm wide and 11 - 50 cm long with pubescence. The terminal inflorescence exist in V-shaped rames of 7 - 97 (usually about 45) per stem. The plant has rhizomes.[2][3]


It is found from North Carolina south to southern and western Florida[1] with disjunct populations in the Bahamas.[4]



Habitats of A. longiberbis include dry, well-drained, sandy soils of longleaf pine-turkey oak sandhills, limerock in pine flatwoods, dunes, wiregrass-palmetto flatwoods, sandy upland old fields, and sand pine-evergreen oak scrubs.[5][1] It grows well in areas of sunlight and semi opened areas and can be found in disturbed habitats such as sandy vacant lots, roadsides, ditches, railroad banks, pine plantations, and waste grounds.

Associated species include Pinus, Quercus, wiregrass, palmetto, turkey oak, Phoebanthus, Psoralia, Schrankia, Smilax auriculata, Helianthemum sp., Cenchrus spinifex, Panicum spp. Heterotheca subaxillaris, Monarda punctata, Quercus hemispherica, and others.[5]


It has been seen flowering in April through October[6] and fruiting between August to November.[5]

In Lake County, Florida, hybridization of A. longiberbis and A. glomeratus var. pumilus has been observed.[7]
