MAT PANIC GRASS
A. A. Reznicek
Panicum meridionale of Michigan Flora.
Sandy open oak forests, drying shores, and fields.
Very narrow-leaved and small plants collected from sandy habitats mostly in southwestern Michigan appear quite distinctive. Other plants fitting the key are more variable, and we may be including some depauperate material of other species here. Stephenson (1984) suggests this taxon is an intermediate between D. implicatum and D. columbianum, but it has narrower leaves and smaller spikelets than either of these species. Gleason & Cronquist (1991) placed it with Panicum leucothrix, which, however, is considered a restricted Coastal Plain species by Freckmann & Lelong (2002) (under Dichanthelium acuminatum subsp. leucothrix). An 1888 O. A. Farwell specimen from a “cliff” in Keweenaw Co. is not mapped.
