Info from Butomus umbellatus[edit]
The info below was included in the article Butomus umbellatus and must have been created in parallel to this monotypic genus article. It should be merged in where appropriate. Rkitko (talk) 17:58, 16 June 2013 (UTC)
Butomus umbellatus, the flowering rush or grass rush, is a perennial aquatic plant, constituting the family Butomaceae. Its name is derived from 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 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 flowers. Introduced into North America as an ornamental plant it has now become a serious invasive weed in the Great Lakes area.
Butomus is a rhizamatous perennial with linear leaves up to 1 metre long, or more. The leaves are triangular in cross-section and arise in two rows along the rhizome.
The inflorescence is umbel-like consisting of a single terminal flower surrounded by three cymes. The flowers are regular and bisexual. 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 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.
Frequently cultivated as an attractive ornamental plant. In parts of Russia the rhizomes are used as food.
