Butomus umbellatus[2]

Butomus is the only known genus in the plant family Butomaceae, native to Europe and Asia. It is considered invasive in some parts of the United States.[3] Two species are recognized:



The Butomaceae family has been recognized by most taxonomists as a plant family; it is sometimes called the "flowering-rush family".

The APG II system, of 2003 (unchanged from the APG system, 1998), also recognizes such a family, and places it in the order Alismatales, in the clade monocots. The family counts a single species, Butomus umbellatus.

At the ranks of family and order, this is the same placement as in the Cronquist system. However, Cronquist assumed a much smaller order and assigned the order to subclass Alismatidae, in class Liliopsida [=monocotyledons].
