Distribution map for Prosartes maculata

Updated 5/15/2018. 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.


No habitat data are available for the sole Michigan site; elsewhere this species occurs in rich woods, particularly on moist forested slopes and coves in the southern Appalachian Mountains. This species has not been seen in the state since 1922.

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.

Associated Plants

No data available for Michigan; associates would likely be such species as large flowered trillium, wild ginger, plantain-leaved sedge, and several other species typical of mesic forests.


Surveys for this species are necessary, as suitable habitat is definitely still present. If found, it would likely require maintenance of the forest canopy and protection from development and excessive timber harvesting.

General Survey Guidelines

Random meander search covers areas that appear likely to have rare taxa, based on habitat and the judgement of the investigator.
