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.
Currently only known from southern Menominee County, where it occurs in oak-pine barrens (oak-jack pine savanna).
Natural Community Types
Black oak, white oak, jack pine, red maple, black cherry, pin oak, hickory, sassafras, service berry, New Jersey tea, sweetfern, beaked hazelnut, wintergreen, huckleberry, sand cherry, dwarf chinquapin oak, low sweet blueberry, little bluestem, big bluestem, sky-blue aster, false foxglove, tickseed, nut grass, flowering spurge, hair grass, tall sunflower, dwarf dandelion, blazing star, wild bergamot, goats-rue, wood betony, needle grass, and birdfoot violet.
This species likely requires natural disturbances associated with prairie habitat such as prescribed fire or brush removal to prevent woody plant succession. Much of this habitat type has been lost or severely degraded.
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
Survey Period: From first week of July to fourth week of July
Survey Comments: Optimal surveys are during bloom period, but can be recognized in fruit past the period indicated
