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 name mucronatum means with a short straight point (Fernald 1970) as is probably in reference to the pointed tips of the petals.

State Ranking Justification [-]
There are 7 known extant populations and about 16 to 18 populations which have not been seen in over 35 years and are considered historical. Ample habitat for this species exists in New York, but New York is close to the northern edge of its range.
