As part of ongoing efforts to understand and document the flora of the southeastern United States, we propose a number of taxonomic changes and report a distributional record. In Rhynchospora (Cyperaceae), we elevate the well-marked R. glomerata var. angusta to species rank. In Dryopteris (Dryopteridaceae), we report a state distributional record for Mississippi for D. celsa, filling a range gap. In Oenothera (Onagraceae), we continue the reassessment of the Oenothera fruticosa complex and elevate O. fruticosa var. unguiculata to species rank. In Eragrostis (Poaceae), we address typification issues. In the Trilliaceae, Trillium undulatum is transferred to Trillidium, providing a better correlation of taxonomy with our current phylogenetic understanding of the family.
