Littorella
''Littorella'' is a genus of two〔(【引用サイトリンク】 Littorella L. )〕 to three species of aquatic plants. Many plants live their entire lives submersed, and reproduce by stolons, but some are only underwater for part of the year, and flower when they are not underwater.〔 == Classification == Molecular data show ''Littorella'' to be sister to the rest of the genus ''Plantago''. Thus, cladistics would allow it to be considered either as a separate genus or as part of ''Plantago''.〔 Some researchers, particularly Rahn in the 1990s, have considered ''Littorella'' to be located within ''Plantago'', but this does not seem to be required given the molecular data and a closer look at morphology.〔
