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.
Michigan's only collection of this species was made along a roadside in dry prairie soil in 1933. Elsewhere this species is generally known from sand prairie relics, sandstone bluffs, and dry river terraces.
Natural Community Types
No data are available concerning associates in Michigan.
The principal need for this species is inventory in southwest Michigan to discover if any extant colonies exist. If found, it would likely benefit from prescribed burning and other management that maintains prairie habitat.
General Survey Guidelines
Random meander search covers areas that appear likely to have rare taxa, based on habitat and the judgment of the investigator.
- Meander search
