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.

Leptoloma cognatum of Michigan Flora.

Dry prairies, old fields, sandy open ground.

The spikelets are narrowly elliptic (unlike most species of Panicum, which genus it somewhat resembles), and often have stripes of silky appressed pubescence.

Records (mostly recent) from north of the middle of the Lower Peninsula are often from along roadsides or in other dry disturbed, sandy areas, and are likely introduced.
