Reported here are five collections of four rare, aquatic plant taxa in Mississippi that were collected as part of routine surveys of Mississippi’s freshwater ecosystems. Voucher specimens reported here were deposited at the Mississippi State University (MISSA) herbarium, with duplicate material deposited at the L.H. Bailey Hortorium (BH) at Cornell University. These collections help expand our understanding of the native aquatic biodiversity of Mississippi, as well as serve as a record of early detection for an introduced taxon of concern: Vallisneria ×pseudorosulata.
