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.
