Description
Andropogon arctatus is a perennial[2] 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.[3]
Distribution
Andropogon arctatus is occasionally found in northern and central peninsular Florida and the central and western regions of the panhandle.[4] The plant is endemic to Florida and Alabama, but there are records showing that this species was found in North Carolina as well.[5]
Ecology
Habitat
This species grows scattered throughout its habitat but is very abundant.[6] It is found in moist, sunny, low grass-sedge clearings and open pine flatwood and savanna communities[7] as well as pinelands.[5] It is found in dry to wet loamy sands and sand pine scrub environments.[4][6] It can also be found in seepage wetlands like pitcher plant bogs or wet pine savannas.[3]
Andropogon arctatus is one of the indicator grass-species for the understory vegetation of Florida’s panhandle seepage savannas.[8]
Associated species include Pinus palustris, Pinus elliottii, Aristida stricta, Hypericum chapmanii, Ilex myrtifolia,[6] Quercus nigra, Quercus minima, Quercus 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, Panicum verrucosum, and Aristida species.
Phenology
Andropogon arctatus has been observed flowering from October to November.[7][9] It has been observed fruiting from October through November.[6]
Seed dispersal
The plumed seeds are wind-dispersed.[3]
Fire ecology
It is maintained by fire.[7] Flowers in the fall after a fire event has occurred that same year.annjohnson[10]
Conservation, cultivation, and restoration
Is listed as vulnerable.[3]
