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 species name, tenuiflora, means slender-flowered. The most obvious distinguishing characterstic of the species is the three small spikes bunched closely together at the end of the slender stem.

State Ranking Justification [-]
There are four known occurrences and relatively few historical occurrences of this species, so it may have always been somewhat rare in the state. The ecological reasons for its rarity are unclear. While this species is near the southern limit of its range in New York, it occupies habitat similar to that of many more common sedges. It is also a species of concern in the state of Maine.
