Family: Aster Family (Asteraceae)

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: G5?
A Global Rarity Rank of G5? means: Secure globally (most likely) - Conservation status is uncertain, but most likely common in the world; widespread and abundant (but may be rare in some parts of its range). More information is needed to assign a firm conservation status.


Did you know?
Unfortunately this beautiful Lactuca has been omitted from many of our popular wildflower guides (except for Peterson‘s Guide) so it probably goes unnoticed. There is one identification tip that is not in field guides and can be seen from a distance. It is the way the inflorescence branches are more open with longer secondary branches that often point in different directions. The common Lactuca biennis or L. canadensis have more compact inflorescences with many more flower heads in them.

State Ranking Justification [-]
There are 5 verified occurrences, and 20 remaining historical sites to check, but populations have been extirpated from 5 sites by development.
