Floating Water-plantain
''Luronium natans'' is a species of aquatic plant commonly known as the floating water-plantain. It is the only recognized species in the genus ''Luronium'', native to western and central Europe, from Spain to Britain to Norway east to Ukraine. Description Stems elongated, rising in the water or creeping and rooting at the nodes. Submerged leaves (if present) basal, linear; floating or aerial leaves elliptical to ovate. Flowers hermaphrodite, long-pedunculate in the axils of the floating or aerial leaves. Stamens 6. Carpels 6–15 in an irregular whorl, free, each with 1 ovule; styles apical. Fruitlets achenial, longitudinally many-ribbed, with a short apical beak. 2''n'' = 42. ''Luronium natans'' can be a difficult plant to identify. It is both very variable and resembles many other aquatic plants with strap-like leaves such as bur-reeds (''Sparganium''), young water-plantain plants (''Alisma''), arrowheads (''Sagittaria''), lesser water-plantain (''Baldellia'') and ...
