Ruppia cirrhosa and R. maritima are two widely used names, each applied respectively to a long‐ and coiled‐pedunculate species or a short‐ and non‐coiled pedunculate species of Ruppia. The nomenclatural history of the two names is outlined here. A lectotype for the name R. cirrhosa is designated and the name is shown to be a homotypic synonym of R. maritima. Consequently, R. spiralis has nomenclatural priority over R. cirrhosa for the long‐ and coiled‐pedunculate Ruppia.
