Family: Mint Family (Lamiaceae)

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: G1G2
A Global Rarity Rank of G1G2 means: Critically Imperiled or Imperiled globally - At very high or high risk of extinction due to rarity or other factors; typically 20 or fewer populations or locations in the world, 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?
This species has the smallest range of any northeastern Pycnanthemum. It was first collected in New York in 1817 with reports continuing up until 1893. This plant was thought to be extirpated from New York, but after a 104 year absence it was rediscovered. Since its rediscovery, two new sites have been located. The species name derives from its resemblance to the European calamint, Clinopodium.

State Ranking Justification [-]
There are three known populations but two of these are quite small. One population is greatly threatened by competition from aggressive non-native plants. This plant is likely limited to the trapp rock along the Palisades, but disjunct populations may be encountered in calcareous areas where numerous other Pycnanthemum species are located.
