Order Alismatales
The order Alismatales as defined in the Angiosperm Phylogeny Website.[1]
|
Family Araceae
The plants of the Araceae (arum family) have numerous small flowers that are part of a spadix, a spike inflorescence on which the flowers are borne on a fleshy stem. The spadix is usually surrounded by a bract called a spathe.
|
Subfamily Orontioideae
The Orontioideae contains just two New York species, both native: Orontium aquaticum (golden club) and Symplocarpus foetidus (eastern skunk cabbage). This subfamily also includes the genus Lysichiton which comprises the western and Asian skunk cabbages, neither of which are know to have naturalized in New York.
|
Orontium
Orontium aquaticum (golden club), the only living species of its grenus, probably reaches the northern extent of its range in New York and adjacent New England. It is considered to be threatened in New York, where it is mostly found in Hudson River tidal marshes but has been reported in acidic bogs and ponds farther inland.

Tribe Arisaemateae
The Arisaemateae includes two genera that can be found in New York: Arisaema and Pinellia. These include the plants known as Jack-in-the-pulpit and green dragon.
|
Arisaema
Two species of Arisaema are native to New York: A. triphyllum (Jack-in-the-Pulpit) and A. dracontium (Green dragon).
Three subspecies of Jack-in-the-Pulpit have been reported in New York. A. triphyllum ssp. triphyllum, a tetraploid with 2n:56 chromosomes, likely originated as a hybrid of subspecies stewardsonii and pusillum, each of which is a diploid with 2n:28 chromosomes.[1] |

Family Butomaceae
Butomus
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 species, 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]
