Very small annual forb (5-20 cm) of dry, open habitats; the finely pubescent stem is forked and branching with narrowly elliptic opposite leaves.

Updated 4/11/2018. 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.
No habitat data are known for Michigan's sole collection of this species, which is known to generally occur in dry woods and openings. This plant has not been documented in Michigan since 1909.
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.
No Michigan associates are known. In the Chicago region, this species occurs with wild quinine, ticklegrass, field milkwort, three-awned grass, prairie cordgrass, grass-leaved goldenrod, orange-grass, and gray goldenrod.
A status survey is recommended to compile more thorough habitat information on this species. If found, it would likely benefit from management that maintains dry oak savanna such as prescribed fire and removal of excessive woody brush.
General Survey Guidelines
Random meander search covers areas that appear likely to have rare taxa, based on habitat and the judgment of the investigator.
