Aldrovanda

edit
 
Aldrovanda vesiculosa
Although the waterwheel plant is listed as endangered globally it is considered potentially invasive in the Northeast, where this carnivorous aquatic plant has been introduced into private ponds by hobbyists and probably transported into the wild on the feet of birds.[1]

Tamarix

edit
 
Tamarix parviflora
Several tamarisk or saltcedar (Tamarix) species are considered invasive in North America, and they can be difficult to distinguish from one another.[1] The New York Flora Atlas lists Tamarix parviflora as naturalized in Suffolk County. iNaturalist shows a 2020 observation of Tamarix parviflora on Shelter Island, but it had only been confirmed to genus level as of 2022.[2]

Limonium
edit
 
Limonium carolinianum (Walter) Britton
sea-lavender
The genus Limonium is generally known as sea lavender or statice. But it's not related to lavender (Lavandula), which is in the Lamiaceae (mint family).

Limonium carolinianum is reported as secure in salt marshes along the New York Atlantic Coast.

According to the Flora of North America, although Limonium leptostachyum was reported from New York by R. S. Mitchell and G. C. Tucker (1997), it's doubtful that it could naturalize New York.[1]

Armeria
edit
 
Armeria maritima
Armeria maritima is native to coastal regions throughout the northern hemisphere but has not been known to naturalize in New York. Its North American distribution is primarily along the west coast, but there is a fairly significant population near Lehigh Gap, Palmerton, Pennsylvania, where it was used for remediation in test plots downwind from zinc smelters that severely damaged the forest on top of Blue Mountain.

Reynoutria
edit
 
Reynoutria japonica
Knotweed (Reynoutria — syns. Polygonum and Fallopia) includes the very common Japanese knotweed (R. japonica var. japonica) and the less common giant knotweed (R. sachalinensis). The hybrid of the two (R. × bohemica or Bohemian knotweed), often occurs mixed in with Japanese knotweed. All three are considered to be very highly invasive in New York State.
