State Rank Reason (see State Rank above)
Muhlenbergia mexicana has not been documented in Montana. A 2001 specimen was re-determined to be Muhlenbergia glomerata , which closely resemble one another. No Montana specimens have been verified (MTNHP Status Review in 2018). There is potential for it to occur in Montana. Potential specimens should be provided to and verified at one of our State Herbaria (University of Montana, Montana State University, or Montana State University-Billings). A conservation status rank is not applicable (SNA) because this plant is not known to occur in Montana.

Callus hairs 0.2-1.5 mm long. Spikelets 2-4.4 mm long, one-flowered, pale green or purple-tinged. Glumes subequal, 2-4.4 mm long, 1-nerved, the midnerves extending into an awn 0.5-1.5 mm long; lemmas 2-3.8 mm long, 3-nerved, awned to about 6 mm long; paleas about length of lemma; anthers 0.3-0.5 mm long.
