Butomaceae

The Butomaceae is a small family of monocotyledonous water or marsh herbs. The family is distinguished by its carpels, which have many ovules and dehiscent fruits. The only species in the Butomaceae family is Butomus umbellatus, commonly known as the flowering rush. This perennial freshwater plant is native to Eurasia and is now found throughout the north temperate zone. Flowering rushes can grow fully submerged or emerge from the water, with tapering leaves and rose-colored flowers arranged in umbels. While they can produce dry fruits, reproduction primarily occurs through bulblets that break off from the root system.12
