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

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.
Two populations that were known extant within the past 20 years were searched for again without success. In both cases more survey work is needed to determine if these populations have become extirpated. Overall, short term trends are not clear.
There are at least 16 populations which have not been seen in over 30 years, some of which, have not been seen in over 100 years. Most of these populations have not been searched for recently and therefore, it is difficult to determine their current status. No population is known to have become extirpated. Six out of the 7 known extant populations were first discovered within the past 20 years. These "new" populations were probably overlooked in the past. Also since this species likes early successional habitats it may move around and not stay in one site for too long. The open habitat that this species requires is very abundant and in general should not be a limiting factor for this species in New York. Overall, long term trends are not clear.
