Sprangletop - Scolochloa festucacea
State Rank Reason (see State Rank above)
Scolochloa festucacea occurs through most of Canada and in portions of mid-western and western States. In Montana it is known from 3 locations collected from 1949 to 1999 in Flathead County. A fourth location from a specimen with a poorly defined location in Carbon county needs to be verified. Surveys to find this species have been unsuccessful.
