DistributionMostly the Piedmont and Sandhills; scattered in the Mountains and upper and central Coastal Plain. Absent toward the coast.

CT and IN south to GA and TX.
AbundanceFrequent to common in the Piedmont; uncommon elsewhere, except very rare to absent in the lower Coastal Plain. The State Rank should be moved to S5 -- as there are records for more than half of the counties, and it is quite numerous throughout the Piedmont.
HabitatFreshwater marshes, river backup channels and oxbows, swamp forests, beaver marshes, ditches.
PhenologyFlowering and fruiting July-October.
IdentificationC. stipitata stands out from most members of the genus by its robust size (up to 5 feet tall) and from all by its bright rosy or rose-pink inflorescence (when mature).
Taxonomic CommentsIn older texts named as Panicum stipitatum.

Members of the genus Coleataenia have been split from Panicum by the subsessile spikelets (nearly stalkless, vs. stalk greater than 2 mm long) and spikelets which grow only on one side of each branch (vs. essentially on all sides). C. anceps and C. rigidula have lower stems relatively flattened, unlike Panicum.
Other Common Name(s)The species needs a better common name! This is the species with reddish inflorescences, not others in the genus such as C. rigidula -- which is generally named as Redtop Panicgrass! Tall Flat Panicgrass is another name.
