Small orchid (10-20 cm) of rich woods; two ovate basal leaves; flower stalk short and stubby, bearing several small two-parted flowers, each with a rounded pink hood and pale lower lip.
Status and Rank
- State Status: T
- State Rank: S2
- Global Rank: G5
|County Name||Number of Occurrences||Year Last Observed|
Updated 1/31/2017. 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.
Found in rich deciduous woods, often near temporary spring ponds in sandy clay or rich loam soils, or in shady, rich microhabitats alongside common spring ephemerals. Vigorous colonies can spread into more open habitat.
Natural Community Types
- Southern hardwood swamp
- Mesic southern forest
- Mesic northern forest
- Floodplain forest
- Wet-mesic flatwoods
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.

This species benefits from conservation of rich forest habitat, and avoidance of excessive logging and change in hydrology. Minimize development and fragmentation. When possible, leave large tracts of unharvested forests and allow natural processes to operate unhindered. Reportedly also very susceptible to herbivory from slugs.
General Survey Guidelines
Random meander search covers areas that appear likely to have rare taxa, based on habitat and the judgement of the investigator.
- Meander search
Survey Period: From first week of May to fourth week of June
