Tall glaucous grass; 5-6 leaves present along the stem; inflorescence very narrow and compact, resembling wheat grass (Agropyron), but with two spikelets per node; glumes very narrow, with thin translucent margins.
Status and Rank
- State Status: SC
- State Rank: S3
- Global Rank: G5
|County Name||Number of Occurrences||Year Last Observed|
Updated 7/21/2017. 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 a diversity of habitats, mostly near Lake Superior. These habitats include: rocky shores, sandy thickets, wooded dunes, and deciduous woods. It often occurs in rocky crevices.
Natural Community Types
- Volcanic bedrock lakeshore
- Mesic northern forest
- Open dunes
- Volcanic cliff
- Boreal forest
- Sand and gravel beach
- Sandstone cliff
- 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.
Northern white cedar, green alder, bunchberry, marsh bellflower, pale Indian paintbrush, shrubby cinquefoil, wild rose, and butterwort. In northern hardwood forests, it may be associated with sugar maple, Eastern hemlock, beech, yellow birch, basswood, white pine, red oak, white cedar, white birch, ironwood, American elm, balsam fir, white baneberry, red baneberry, wild leek, wild sarsaparilla, jack-in-the-pulpit, blue cohosh, enchanter's nightshade, bunchberry, blue-bead lily, Canada mayflower, Solomon's seal, false spikenard, twisted stalk, bellwort, star flower, nodding trillium, common trillium, maiden hair fern, lady fern, rattlesnake fern, spinulose woodfern, stiff clubmoss, shining clubmoss, ground pine, striped maple, leatherwood, fly honeysuckle, and maple-leaf viburnum.
Primarily requires protection of the shoreline habitat and perpetuation of natural disturbance (winter ice, storms, wind) and hydrological regimes. This community occupies a stressed, potentially unstable environment; many of the species found in this community do not tolerate later stages of succession and require management that prevents woody plant encroachment. Protect from development.
General Survey Guidelines
Random meander search covers areas that appear likely to have rare taxa, based on habitat and the judgement of the investigator.
