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.
Known only from 1916 collections along Lake St. Clair, where this species was found in wet, open places and low ground. This species may possibly be discovered in lakeplain prairie remnants.
Natural Community Types
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.
No associate data are known for Michigan. In the Chicago region this species occurs in wetland habitats similar to those where the common purple monkey-flower (Mimulus ringens) is found.
The primary need for this species at present is continued status surveys to determine if extant populations can be discovered. If found, protection of hydrology is likely to be critical, and prescribed burning may also be beneficial.
Random meander search covers areas that appear likely to have rare taxa, based on habitat and the judgement of the investigator.
