Frasera caroliniensis basal leaves Troy Weldy
Family: Gentian Family (Gentianaceae)

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: 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: 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 lifecycle of green gentian is known as monocarpic. It lives for up to 30 years as a cluster of basal leaves then produces one large flower stalk and dies. So this is a plant that dies shortly after its first "pollination encounter" (Committee on The Status of Endangered Wildlife In Canada 2006). It's flowering stalk is one of the largest of any wildflower species in New York. In the past, its roots were used to prepare medicines for stomach troubles (Hatfield 2004).

State Ranking Justification [-]
Currently there are 17 populations in western New York, the majority of them in Letchworth State Park. There are only 4 historical occurrences so many more populations are not expected to be found. Presently the populations are stable but threats from logging and invasive plants may reduce their abundance.
