DistributionMostly the Piedmont and the Sandhills; scarce in the Mountains; disjunct to Hyde County in outer Coastal Plain.

P.E.I. to NE south to GA and eastern TX.
AbundanceCommon in the Piedmont, uncommon in the Sandhills and the Mountains, and rare in the outer Coastal Plain. Oddly, the NCNHP's State Rank is S2?, though it may be that when the species was ranked many years ago, it was included within S. atrovirens, and the full distributions of these two taxa were poorly known. The website editors suggest S5 as the State Rank now.
HabitatFreshwater marshes, river shores, beaver ponds, impoundments, roadside ditches, wet trailsides and woods roads, wet depressions in pine-wiregrass uplands.
PhenologyFlowering and fruiting June-September.
IdentificationThe stems generally are about 3 feet tall, and stem leaves are few. The inflorescence is usually 2-parted: the upper group of spikelet clusters is separated from the lower group by rather erect stalks. It is very similar to S. hattorianus, but Georgia Bulrush has 0-3 seed bristles (vs. 5-6 in the other species), and the bristles are much shorter than the seed body (vs. about as long as the seed body in S. hattorianus). It also resembles S. flaccidifolius; see that account for differences.
Taxonomic CommentsIn older texts, it has been lumped within S. atrovirens, which has not been conclusively proven to occur in NC.

Note that the genus Schoenoplectus has been split from Scirpus and includes plants with sessile spikelets, or with spikelets with a few branches (vs. open, widely branching inflorescences). Most of our Schoenoplectus species appear to have no leaves (exceptions are S. etuberculatus and S. subterminalis), whereas Scirpus taxa have well-developed basal and stem leaves.
