Please try our next iteration of the Michigan Flora Online here. Beginning on February 1, 2023, michiganflora.net will point to this new site.
The new site offers several benefits over the existing website, including real coordinate mapping, giving a clearer view of the density of documentation as well as more precision about plant distributions and their link to landforms. We will also have the ability to update species pages more regularly, both in terms of new collections and as more existing Michigan specimens are georeferenced. In addition, we have a better photo display, and offer indented keys.

Roadsides, railroads, and disturbed ground generally; also in more natural habitats such as shores. A common weed introduced from the west and first collected in 1875 in Ionia Co., though known from the shores of Lake Superior as early as the 1880’s and conceivably in small part native.
The florets of the lateral spikelets of each group of 3 in this species are reduced to inconspicuous bristles; these spikelets are short-pediceled, the awn-like glumes on the pedicel thus forming a Y-shaped structure with the bristle-like reduced floret at the fork. The awns of the narrow fertile central floret are similar to the glumes of all three spikelets, and the entire spike appears to be a large mass of upwardly scabrous awns, making most unmanageable specimens when the dry rachis separates between each group of spikelets.
