			[[Image:Butomus umbellatus.JPG\|thumb\|250px\|''The flowers of ''Butomus umbellatus'']]'''Butomus''' is the sole [[genus]] in the [[Monotypic\|monogenetic]] plant [[family (biology)\|family]] '''Butomaceae''', containing the single species '''''Butomus umbellatus''''', also known as '''flowering rush''' or '''grass rush'''.

			The plant is a [[Rhizome\|rhizomatous]], hairless, [[perennial plant\|perennial]] [[aquatic plant]]. Its name is derived from [[Greek language\|Greek]] ''bous'', meaning "cow", "ox" etc and ''tome'', a cut (the verb 'temnein' meaning "to cut"), which refers to the plant's swordlike leaves.

			Other than suggested by its English common name, it is not a true [[Juncaceae\|rush]]. It is native to [[Eurasia]] and grows on the margins of still and slowly moving water down to a depth of about 3 m. It has pink [[flower]]s. Introduced into [[North America]] as an [[ornamental plant]] it has now become a serious [[invasive species\|invasive weed]] in the [[Great Lakes]] area. In [[Israel]], one of its native countries, it is an [[endangered species]] due to the dwindling of its habitat. It can also be found in [[Great Britain]] locally, for example Butomus umbellatus at [[Caldicot and Wentloog Levels]] otherwise known as Gwent Levels [[SSSI]]<ref>Natural World Magazine, Spring 2009, The Wildlife Trust, published by Think publishing</ref>

			The plant has linear, pointed [[leaves]] up to 1 metre long, or more. The leaves are triangular in cross-section and arise in two rows along the [[rhizome]]/base. They are untoothed, parallel veined and twisted.<ref name="The Wild Flower Key">{{cite book \|last=Rose \|first=Francis\|authorlink=Francis Rose \|title=The Wild Flower Key \|year=2006 \|publisher=Frederick Warne & Co\|isbn=978-0723251750 \|pages=480-481}}</ref>

			The [[inflorescence]] is [[umbel]]-like consisting of a single terminal [[flower]] surrounded by three [[cymes]]. The [[flowers]] are regular and [[bisexual]], 2 to 3 cm across. There are three petal-like [[sepals]] which are pink with darker veins. They persist in the [[fruit]]. The three [[petals]] are like the sepals but somewhat larger. 6 - 9 [[stamens]]. [[Carpels]] superior, 6 - 9 and slightly united at the base. When ripe they are obovoid and crowned with a persistent [[carpel\|style]]. Ovules are numerous and found scattered over the inner surface of the [[carpel]] wall, except on the midrib and edges. [[Fruit]] is a follicle. The [[seeds]] have no endosperm and a straight embryo. It flowers from July until September.

			Frequently cultivated as an attractive ornamental plant. In parts of Russia the rhizomes are used as food.
