Comments
Until recently, this plant was known in Virginia only from two historical collections by Fernald and Long from longleaf pine barrens in southeastern Virginia; these were reported as A. virginicus var. glaucus, a synonym of Andropogon capillipes. The same two records were subsequently determined by Campbell as A. virginicus var. decipiens. Andropogon capillipes is not known to occur in Virginia, reaching its northern limit in North Carolina.

Since the two historical records were discovered, populations of var. decipiens have been documented in interdune swales on the Eastern Shore and at False Cape, as well as from hardpan flats in Halifax Co., boggy clearings in Buckingham, Hanover, King William, and Henrico counties, and a Shenandoah Valley sinkhole pond in Augusta Co.
Further field inventory and collection efforts will no doubt reveal that it is more widespread in eastern Virginia than current records indicate.
Habitat
Moist to dry sandy woodlands and clearings, in areas now or formerly occupied by Longleaf Pine; recently documented in boggy interdune swales, alternately wet-and-dry flats, depression ponds, and artificial impoundment shores. Infrequent in the s. and c. Coastal Plain; apparently rare in the Piedmont and disjunct to Augusta County in the Ridge and Valley province; additional field and herbarium studies are needed to clarify the status of this taxon, which may be somewhat overlooked.
