Tall perennial grass of rocky openings and shores; leaves narrow, flat, scabrous; inflorescence tightly contracted, awns of lemma twisted at base.
Status and Rank
- State Status: SC
- State Rank: S1
- Global Rank: G3Q
|County Name||Number of Occurrences||Year Last Observed|
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.
Few habitat data are available. The few specimens that exist were noted as being collected from mossy rock crevices, rocky openings, the sandy shore of an inland lake, and a rich shrub-dominated fen.
Natural Community Types
- Sand and gravel beach
- Volcanic bedrock lakeshore
- Northern fen
- Granite bedrock glade
- Volcanic bedrock glade
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 data are available concerning associates in Michigan.
Little is known about this species; primary conservation need at present is to validate former localities and obtain better data.
General Survey Guidelines
Random meander search covers areas that appear likely to have rare taxa, based on habitat and the judgement of the investigator.
- Meander search
