Taxonomic Comments
The two varieties of Rhynchospora corniculata (var. interior and var. corniculata) are considered indistinct by Kartesz (1999), Kral in FNA vol. 23 (2002b), McMillan (2007), and Weakley and Southeastern Flora Team (2025) who note "Var. interior, probably not worth recognition, is distinguished by a shorter and narrower achene, the summit barely broader than the base of the tubercle, and occurs in the Mississippi drainage."
