State Rarity Rank: S1
A State Rarity Rank of S1 means: This plant is endangered/critically imperiled in New York because of extreme rarity (typically 5 or fewer populations or very few remaining individuals) or is extremely vulnerable to extirpation from New York due to biological factors.

Global Rarity Rank: G5
A Global Rarity Rank of G5 means: This species is demonstrably secure globally, though it may be quite rare in parts of its range, especially at the periphery.


Did you know?
The genus was named by Linnaeus after the Sesuvii, a Gallic tribe mentioned by Cesar as part of the Armoric states which, like Sesuvium, were located in the Atlantic maritime region in present-day France (McDevitte and Bohn 1869).

State Ranking Justification [-]
There are three existing populations and two of them have over 100 plants each. The smaller population is in a pristine and well-protected area. There are also five historical records from the late 1800s to the mid-1940s which need to be resurveyed to see whether the plants are still there.
