Key Characteristics

Small branching forb (60 cm) of forested floodplains; leaves alternate and rounded, becoming narrower up the smooth stem; small, white, tubular flowers borne in hemispherical clusters, with two narrow, lance-shaped bracts at the base; tiny (3-4 mm) fruiting pods are triangular in cross-section.

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

Goosefoot corn-salad is found in wet sites in forested floodplains with a somewhat open overstory.

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

Black maple, basswood, beech, buckeye, american elm, spicebush, prickly gooseberry, false mermaid, kidney-leaf buttercup, blue-eyed Mary, black snakeroot, downy yellow violet, and appendaged water-leaf.

Management Recommendations

To preserve this species, protect from human disturbances such as development, deforestation, and alterations in hydrological regimes. There is little detailed habitat information for this species, thus status surveys are recommended in order to better understand ecological requirements.

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 first week of May to fourth week of June
