Diagnostic Characteristics:
This sedge has a lenticular or flattened winged perigynia that is generally reniform in shape and is finely granular-papillose, leaf sheaths have an elongate hyaline area, and all the uppermost and lowermost spikes generally sessile and similar in length (the ovales group); the staminate flowers are positioned at the bottom of the infloresence. This plant occurs in the Mississippi Embayment area or possibly the Gulf Coastal Plain.

Management:
Avoid changes in moisture/hydrologic conditions at the site. Changes could result from overstory removal, stream/wetland alteration or vegetation removal that would result in increased erosion. Invasion by exotic pest plants could threaten this species and should be removed.
