|Trailing wild Bean|
Photo by Susan R. Crispin
Low, twining to trailing annual vine (up to 1 m) of open, moist, sandy soil; alternate trifoliate leaves sparsely hairy beneath, the leaflets often with a coarse lobe on one side; producing peduncles from leaf axils that are few-flowered, bearing pinkish, pea-like flowers and greenish pods that are coiled after seed dispersal.
Status and Rank
- State Status: SC
- State Rank: S3
- 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.
Trailing wild bean is found in sandy soil, thickets on disturbed ground, roadsides, ditch banks, beaches, and dunes.
Natural Community Types
- Emergent marsh
- Mesic sand prairie
- Lakeplain wet prairie
- Lakeplain wet-mesic prairie
- Great lakes marsh
- Sand and gravel beach
- Interdunal wetland
- Southern shrub-carr
- Southern wet meadow
- Coastal plain marsh
- Wet prairie
- Wet-mesic prairie
- Wet-mesic sand prairie
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.

To preserve this species, protect habitat and maintain wetland hydrology and natural cycle of fluctuations in emergent marsh. Agricultural run-off has negative impacts. Protect habitat from development.
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
