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: S2S3
A State Rarity Rank of S2S3 means: Imperiled or Vulnerable in New York - Very vulnerable to disappearing from New York, or vulnerable to becoming imperiled in New York, due to rarity or other factors; typically 6 to 80 populations or locations in New York, few individuals, restricted range, few remaining acres (or miles of stream), and/or recent and widespread declines. More information is needed to assign a single conservation status.

Global Rarity Rank: G4G5
A Global Rarity Rank of G4G5 means: Apparently or Demonstrably Secure globally - Uncommon to common in the world, but not rare; usually widespread, but may be rare in some parts of its range; possibly some cause for long-term concern due to declines or other factors. More information is needed to assign a single conservation status.


Did you know?
Hormathodes means necklace-like (Fernald 1970) which is in reference to the spikes on the stems which appear somewhat like beads on a necklace. Some other species fit this description as well.

State Ranking Justification [-]
There are fifteen known populations and over 20 historical sites. Many of the known sites are small or within degraded habitats. This plant is located along the upper borders of marsh habitats, a habitat that has been widely manipulated and subject to significant invasive species challenges. Phragmites and development have been the prime threats. As many as ten of the former historical locations are now extirpated. Additional populations are likley, but these may be small and also threatened by invasive species.
