Ruppia cirrhosa |
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]
