Family: Sedge Family (Cyperaceae)

State Protection: Threatened
listed species are those with: 1) 6 to fewer than 20 extant sites, or 2) 1,000 to fewer than 3,000 individuals, or 3) restricted to not less than 4 or more than 7 U.S.G.S. 7 minute topographical maps, or 4) listed as threatened by U.S. Department of Interior.

Federal Protection: Not Listed

State Rarity Rank: S2
A State Rarity Rank of S2 means: This plant is threatened/imperiled in New York because of rarity (typically 6-20 populations or few remaining individuals) or is 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?
This sedge can be searched for very late in the season as it tends to stay green into October and even early November. The spikelets are host to a fly parasite which may result in deformed fruits. The specific name is derived from the resemblance of its inflated fruits to hops (Humulus lupulus).

State Ranking Justification [-]
There are 16 reported populations, but only seven of these have more than 25 plants. There are about 20 historical populations and these should be surveyed to determine if the plants are still present. Difficulty with keys/characters have led to misidentifications and the late ripening of fruit has likely limited the number of successful surveys for this plant. This plant has likely always been uncommon within New York as it has a limited distribution, specific habitat, and typically has small populations.
