Cuscuta plants that were observed growing entirely submersed and parasitizing the aquatic macrophyte Hygrophila polysperma in the San Marcos and Comal Rivers in Texas, are identified genetically as C. obtusiflora. This note documents the first molecular identification of any Cuscuta species naturally growing underwater or parasitizing a submersed aquatic plant.
