Updated 4/11/2018. 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.
Occurs in cold headwater streams and seeps within a variety of non-forested and forested wetlands, including prairie fens, southern wet meadow, southern shrub-carr, rich tamarack swamp, hardwood-conifer swamp, and rich conifer swamp.
Natural Community Types
- Prairie fen
- Headwater stream (1st-2nd order), riffle

- Headwater stream (1st-2nd order), run
- Emergent marsh
- Floodplain forest
- Hardwood-conifer swamp
- Rich conifer swamp
- Rich tamarack swamp
- Southern shrub-carr
- Southern wet meadow
For each species, lists of natural communities were derived from review of the nearly 6,500 element occurrences in the MNFI database, in addition to herbarium label data for some taxa. In most cases, at least one specimen record exists for each listed natural community. For certain taxa, especially poorly collected or extirpated species of prairie and savanna habitats, natural community lists were derived from inferences from collection sites and habitat preferences in immediately adjacent states (particularly Indiana and Illinois). Natural communities are not listed for those species documented only from altered or ruderal habitats in Michigan, especially for taxa that occur in a variety of habitats outside of the state.
Natural communities are not listed in order of frequency of occurrence, but are rather derived from the full set of natural communities, organized by Ecological Group. In many cases, the general habitat descriptions should provide greater clarity and direction to the surveyor. In future versions of the Rare Species Explorer, we hope to incorporate natural community fidelity ranks for each taxon.
Tamarack, grass-of-parnassus, shrubby cinquefoil, Virginia mountain mint, Ohio goldenrod, Riddell's goldenrod, Indian grass, hardstem bulrush, three-square, twig-rush, prairie dropseed, small white lady's slipper, bog valerian, edible valerian, rush, golden-seeded spike-rush, spike-rush, joe-pye weed, pitcher-plant, sun dew, Sphagnum mosses, common boneset, little bluestem, big bluestem, blue-joint grass, whorled loosestrife, black-eyed Susan, marsh fern, bog birch, dogwoods, willows, alder-leaved buckthorn, meadowsweet, water hemlock, bog clearweed, strict sedge, and marsh bellflower.
The primary ecological need is the protection of hydrology and perpetuation of cool groundwater sources. Prescribed burns to maintain open, grassy wetlands are also likely beneficial as this species requires a mostly open canopy.
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 June to fourth week of August
Survey Comments: Restricted to cold alkaline springs and small streams.
