Sphenopholis obtusata (Michx.) Scribn.
Common Name: PRAIRIE WEDGEGRASS
Coefficient of Conservatism: 8
Coefficient of Wetness: 0
Wetness Index: FAC
Physiognomy: Nt P-Grass

Dry open forests (e.g., oak-hickory), shores, prairie-like areas. The inflorescence is dense and contracted, rather resembling that of Koeleria macrantha, while in S. intermedia it is more open and lax. 

Both the Houghton and Keweenaw Co. records were gathered by O. A. Farwell in 1926; each specimen, however, being one of Farwell's notorious "½" numbers, there is substantial suspicion of label error. Otherwise the species has never been seen in the Upper Peninsula.
