State Protection: Endangered
listed species are those with: 1) 5 or fewer extant sites, or 2) fewer than 1,000 individuals, or 3) restricted to fewer than 4 U.S.G.S. 7 minute topographical maps, or 4) species listed as endangered by U.S. Department of Interior.

Federal Protection: Not Listed

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 name is derived from the Greek words meaning bulb and rush, and refers to the underground corms that characterize this genus. This species is probably of hybrid origin because its characters and habitat preference is intermediate between the freshwater species Bolboschoenus fluviatilis and the salt water species Bolboschoenus robustus (Flora of North America 2002).

State Ranking Justification [-]
There are four existing populations and three of them are of good size. There are three additional historical locations which are probably extirpated.
