Author(Mohr) Weakley & LeBlond
DistributionMostly the outer southern Coastal Plain, ranging inland to southeastern Cumberland County and coastally north to Onslow County. Recently split from A. capillipes (LeBlond and Weakley 2011).

Coastal Plain, NC to southern FL and eastern TX; southern NJ; Bahamas.
AbundanceUncommon. As this species was only recently pulled from A. capillipes, there is uncertainty about its abundance level, especially as both species have similar ranges, though this species occurs farther inland than does A. capillipes. The website editors have a tentative State Rank of S3? for now.
HabitatExposed shores of sinkhole ponds, depression meadows, wet pine savannas -- strictly a wetland species, as opposed to the other species, which often occurs in uplands.
PhenologyFlowering and fruiting September-October.
IdentificationThis is one of several NC bluestems with glaucous (chalky white or bluish white) stems and leaves. It is very similar to A. capillipes, from which it has been split off. A. dealbatus differs in growing in wetter habitats, has longer spikelets (mostly 3.5-3.9 mm long vs. 3.2-3.5 mm long in A. capillipes), and has broader leaves (averaging 5.0 mm wide vs. averaging 3.5 mm wide).
Taxonomic CommentsFormerly included within A. capillipes.

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.
