County Distribution Map for [SNAME]

Updated 04/16/2014. 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.

Habitat

The only plant entirely endemic to Michigan, this monkey-flower is found in cold calcareous springs, seeps, and streams through northern white-cedar as well as at the base of bluffs near the Great Lakes shoreline.

Natural Community Types

Associated Plants

Northern white cedar, balsam fir, tag alder, marsh-marigold, watercress, impatiens, jewelweed, and forget-me-not.

Management

This species requires maintenance of cold water source. Prevent disruptions to hydrology, including flow, oxygenation, turbidity.

General Survey Guidelines

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