This sedge, in the section Ovales, 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 inflorescence. This plant occurs in the Mississippi Embayment area or possibly the Gulf Coastal Plain.
