Family: Sedge Family (Cyperaceae)

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: G4
A Global Rarity Rank of G4 means: This species is apparently secure globally (typically with more than 100+ populations), though it may be quite rare in parts of its range, especially at the periphery.

Did you know?
The specific epithet venusta means beautiful or graceful (Stearn 2004). One of its common names is "graceful sedge." This sedge, like many plants that reach their north limit in New York, is restricted to Long Island.

State Ranking Justification [-]
Only known from a single site on Long Island. There are four other historical locations and two extirpated sites, all on Long Island. Long Island represents this species' northern range extent. There is very little suitable habitat remaining on Long Island, so the chances of finding new populations is low.
