State Rarity Rank: S1S2
A State Rarity Rank of S1S2 means: Critically Imperiled or Imperiled in New York - Especially or very vulnerable to disappearing from New York due to rarity or other factors; typically 20 or fewer populations or locations in New York, very few individuals, very restricted range, few remaining acres (or miles of stream), and/or steep declines. More information is needed to assign a single conservation status.

Did you know?
The bristly hairs on the margin of the membrane surrounding the stem at the base of the leaf (ochrea) give this plant its species name (Fernald 1950).

State Ranking Justification [-]
There are four existing populations but all of them have 100 plants or fewer. There are 22 additional historical records from the late 1800s through the 1950s which need to be resurveyed. One population no longer exists because its habitat has been destroyed.
