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

Known until recently only from a First Survey collection (1838) from Berrien County and 1916 collections along Lake St. Clair, where this species was found in wet, open places and low ground. Recently collected from a wet forest at the base of a ravine above a river floodplain.

Natural Community Types

  • Unknown

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

At the recently documented location, this species occurs with:

Trees: Acer saccharum (sugar maple), Fraxinus pennsylvanica (green ash), Quercus rubra (red oak).

Shrubs/Woody Vines: Lindera benzoin (spicebush), Parthenocissus quinquefolia (Virginia creeper), Sambucus canadensis (common elder), Solanum dulcamara (bittersweet nightshade).

Herbs: Bidens frondosa (common beggar-ticks), Boehmeria cylindrica (false nettle), Cinna arundinacea (wood reedgrass), Geum canadense (white avens), Glyceria striata (fowl manna grass), Impatiens capensis (spotted touch-me-not), Iris virginica (wild blue flag), Leersia oryzoides (cut grass), Lysimachia ciliata (fringed loosestrife), Pilea pumila (clearweed), Ranunculus hispidus var. nitidus (swamp buttercup), Samolus parviflorus (water-pimpernel), Scutellaria lateriflora (mad-dog skullcap), Sium suave (water-parsnip), Symphyotrichum lanceolatum (panicled aster), S. lateriflorum (calico aster).

Management Recommendations

The primary need for this species at present is continued status surveys to determine if additional extant populations can be discovered. Protection of hydrology is likely to be critical.

Survey Methods

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 fourth week of June to first week of September
