DistributionMostly the outer Coastal Plain, extending inland to Robeson and Scotland counties.

Coastal Plain, southeastern VA to northwestern FL and southwestern LA.
AbundanceRare to locally uncommon. The NCNHP database lists 28 records, most still extant, and many in good to excellent condition. This is a Significantly Rare species.
HabitatWet to moist Longleaf Pine savannas. Nearly all sites in NC are in good to high quality natural areas, as opposed to damp clearings or ditches.
PhenologyFlowering and fruiting September-October.
IdentificationThis is a tall and robust bluestem, stems mostly 3-5 feet, with the leaves being shaggy-hairy. Each cluster of the inflorescence contains 4-7 (or more) racemes vs. 2-5 in other bluestems; the raceme sheaths are wider than in other bluestems (5.3-8.0 mm wide vs. 2.0-4.8 wide in the others).
Taxonomic CommentsA synonym is A. liebmannii var. pungensis.

While the genus Andropogon is quite easy to recognize in the field, ID of species is not so easy and there are no shortcuts. Readers are strongly advised to read the introductory paragraphs in Weakley (2018) and to use his key. Once one has successfully keyed out several species, or compared collections with verified specimens, one can learn to recognize them in the field.
