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.

Did you know?
The decline in numbers of this violet is very similar to the decline of the silvery aster. Once widespread on Long Island, it is now only known from one location, even though there seems to be abundant habitat left.

State Ranking Justification [-]
There is only one existing population of less than 50 plants. This was once more widespread on Long Island with 30 historical records, but most of them have been extirpated by development.
