FNA5: "Rumex conglomeratus often is confused with immature specimens of R. obtusifolius, as well as with other species (e.g., R. sanguineus). Its distribution in North America is insufficiently known, and some literature records may refer to R. obtusifolius.
Rumex conglomeratus and R. sanguineus were placed in subsect. Conglomerati Rechinger f. (K. H. Rechinger 1937)."
