Small slender forb of open oak woods; leaves elliptic and well-spaced along the stem, with inconspicuous wings extending from the leaf base down the stem, but not reaching to the leaf below; flowers yellow with tiny sepals (3 mm) that lack marginal hairs.

Updated 5/15/2018. 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 open oak forests, upland woods, dry and mesic lakeside and riparian forests in the southern Lower Peninsula.
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.
Pennsylvania sedge, bird's-foot violet, pussy-toes, wood rush, goldenrod, harebell, round-leaved dogwood, shadbush, broad-leaved panic grass, Virginia creeper, bracken fern, and meadowsweet.
As a plant primarily of open woodlands, this species may suffer from canopy closure as well as clear cutting. Management that maintains oak savanna such as prescribed burning and brush clearing may be beneficial.
General Survey Guidelines
Random meander search covers areas that appear likely to have rare taxa, based on habitat and the judgment of the investigator.
