Description
A. tracyi is a graminoid perennial that is a member of the Poaceae family [2]. Like other species in the genus, A. tracyi produces chasmogamous flowers with racemes in sets of two, and the peduncles, spikelets, and anthers are considered long in comparison to other Andropogon.[3]
Distribution
Andropogon tracyi is endemic to the longleaf pine range from southeastern Virgnia to central Florida and west to southeast Texas.[4]
Ecology
Habitat
The Andropogon genus is widespread throughout the North American continent, but A. tracyi is a more rare species found in upland pine communities [5]. It can be found in habitats ranging from disturbed sites like dry loamy sand along roads, and banks along highways, to natural habitats such as scrub oak barrens, dry ridges, high sandy ridges, and other sandy loams. [6]
Phenology
A. tracyi has been seen to be flowering during the month of November, and fruiting during the same time period. [6]
Herbivory and toxicology
A. tracyi is used by quail species in the community for nesting, providing protection for the young from predators.[7]
