Ruppia cirrhosa is a species of aquatic plant known by the common names spiral ditchgrass^[2] and spiral tasselweed.^[3] It is native to north Africa, South Africa and parts of Europe,^[1] where it grows in freshwater bodies, such as lakes. It is a thread-thin, grasslike perennial herb which grows from a rhizome anchored in the wet substrate. It produces a long, narrow inflorescence tipped with two tiny flowers. As the fruit develops the peduncle of the inflorescence curls into a neat spiral.^{[citation needed]}

Taxonomy and nomenclature

A lectotype for this name is designated and the name is shown to be a homotypic synonym of R. maritima.^[4] Consequently, R. spiralis has nomenclatural priority over R. cirrhosa for the long- and coiled-pedunculate Ruppia.
