Taxonomic notes

Synonym: A. arctatus Chapman


It is a perennial. [1] Perennial grass growing up to 1.5 m tall. The leaves are long and narrow and tend to curl. The spikelets are numerous and have paired racemes that grow from the sheaths. The flowers are densely covered with tawny hairs. The seeds are wind-dispersed. [2]


It is occasionally found in northern and central peninsula of Florida; central and western panhandle. [3] It is found in Florida and Alabama. There is records showing that this species was found in North Carolina as well. [4]



This species grows scattered throughout its habitat but is very abundant.[5] It is found in moist, sunny, low grass-sedge clearings and open pine flatwood and savanna communities [6] as well as pinelands. [4] It is found in dry to wet loamy sands and sand pine scrub environments.[3] [5] Associated species include Pinus palustris, P. elliotii, Aristida stricta, Hypericum chapmanii, and Ilex myrtifolia.[5] Other associated species include Quercus nigra, Q. minima, Q. elliottii, Magnolia virginiana, Ilex glabra, Clethra alnifolia var. tomentosa, Gaylussacia tomentosa, Vaccinium myrsinites, Kalmia hirsuta, Serenoa repens, Myrica cerifera var. pumila, other Andropogon species, Schizachyrium sp., Anthaenantia rufa, Panicum rigidulum, P. verrucosum, and Aristida species. It can also be found in seepage wetlands like pitcher plant bogs or wet pine savannas. [2] Andropogon arctatus is one of the indicator grass-species for the understory vegetation of Florida’s panhandle seepage savannas. [7]


It flowers from late September to frost.[6] It has been observed fruiting from October through November.[5]

Seed dispersal

The plumed seeds are wind-dispersed. [2]

Fire ecology

It is maintained by fire. [6] Flowers in the fall after a fire event has occurred that same year.annjohnson[8]
