Family: Aster Family (Asteraceae)
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 the 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: G5T4T5
A Global Rarity Rank of G5T4T5 means: Apparently or Demonstrably Secure globally - The subspecies/variety is 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. (The species as a whole is common globally.) Did you know? The genus named Eupatorium honors Mithridates Eupator, a ruler of the region Pontus on the southern edge of the Black Sea, who reportedly used a species of the genus in medicine (Fernald 1970). The species and variety name refer to the leaves which resemble a species of the European hyssop, and have larger and more ragged teeth than the typical variety of this species. |

| State Ranking Justification | [-] |
There are 10 existing populations but only three of them are in good to excellent condition. The others are small and may not have good long-term viability. There are four historical occurrences.
| Short-term Trends | [-] |
Current populations seem stable although more survey work needs to be done to evaluate all populations since many have not been resurveyed in recent years.
| Long-term Trends | [-] |
This species doesn't seem to have been very common in New York although populations may have been overlooked because it is not readily identifiable. There are now twice as many current populations as historical populations so the trend seems to be increasing. The common variety of this species is very common and more survey work to distinguish this rare variety may increase the number of occurrences found.
