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: G5T5
A Global Rarity Rank of G5T5 means: Secure globally - Both the species as a whole and the subspecies/variety are common in the world; widespread and abundant (but may be rare in some parts of its range).

Did you know?
The genus Bartonia was named for the famous Philadelphia botanist Benjamin Smith Barton by fellow Philadelphia botanist Henry Muhlenberg (Fernald 1950). It is one of only two genera that Muhlenberg named. Both botanists died in 1815, seven months apart (Lee 1999).

State Ranking Justification [-]
There are five known populations but only two of them have exact numbers of plants and they are small. The remaining populations are assumed to be small. There are 20 historical occurrences.
