No known occurrences in Michigan
Updated 05/08/2013. Information is summarized from MNFI's database of rare species and community occurrences. Data may not reflect true distribution since much of the state has not been thoroughly surveyed.
The only known Michigan collection is from the Keweenaw Peninsula around the turn of the century. In the heart of its range in the northwest and in the northeastern Canadian provinces, it is known from dry conifer and mixed forests as well as grassy mountain slopes.
Natural Community Types
No data exists on associated species in Michigan.
Little is known of the biology and ecology of this species, though it may benefit from moderate levels of disturbance that creates and maintains small openings and colonization sites.
General Survey Guidelines
Random meander search covers areas that appear likely to have rare taxa, based on habitat and the judgement of the investigator.
- Meander search
Survey Period: From first week of May to fourth week of September
