Family Butomaceae[edit]

Butomus umbellatus

The sole species of Butomaceae (the flowering rush family) is the aquatic Eurasian plant Butomus umbellatus, which is listed as moderately invasive in New York. Its first appearance in North America was in the St. Laurence River in 1897, and it is now a problem weed in the Great Lakes.[1]

Studies by L. C. Anderson in 1974 found that the naturalized North American Butomus populations had separate sources. Those east of Niagara Falls, introduced near the St. Lawernce River, originated in eastern Asia. Those west of the Falls were introduced near Detroit, and were from western Euraasia. R. L. Stuckey, in 1994, recognized these two groups as separate speceies, with B. umbellatus, from western Eurasia, found west of the Falls, and B. junceus, from eastern Asia, found east of the falls. [2] B. junceus is not widely accepted as a separate species at this time, but if it were to be accepted, New York's populations would probably be considered to be B. junceus.[3][4]
