State Rank Reason (see State Rank above)
Bromus latiglumis has not been documented in Montana (Lesica et al. 2012; Postings as of October 23, 2019 on the Consortium of Pacific Northwest Herbaria [http://www.pnwherbaria.org] and Rocky Mountain Herbarium [http://rmh.uwyo.edu] portals). No Montana specimens have been verified (MTNHP Status Review in 2018). A reported 2010 observation is likely a mis-identification and no specimen was collected. There is potential for it to occur in Montana, and potential specimens should be reported and confirmed by 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.
General Description
This is adapted from the Flora of the Great Plains (McGregor et al. [eds.] 1986).PLANTS : Cespitose perennials 55-130(-160) cm tall. Culms mostly glabrous, internodes usually 10 or more.LEAVES : Blades 10-30 cm long, 3.5-11(-13) mm wide, glabrous to scabrous or (rarely) sparsely appressed-pubescent; sheaths glabrous to densely retrorse-pilose; auricles present and conspicuous (unless broken off); ligules mostly less than 1.5 mm long, often pubescent. INFLORESCENCE : Panicle 10-24 cm long, open, the branches spreading to ascending, somewhat flexuous. Spikelets 5-10(-12)-flowered, 15-33 mm long, 4-9 mm wide. Glumes and lemmas usually hairy. First glume mostly 5-7 mm long, 1-nerved; second glume mostly 6.5-9 mm long, 3-nerved; lowest lemma 8.5-11 mm long, awned 1-5 mm; anthers 1.5-2.8 mm long.
Diagnostic Characteristics
In Montana characteristics of Bromus latiglumis and Potential specimens should be reported and confirmed by one of our State Herbaria :
Habitat
Shaded or open woods, along stream banks, and on alluvial plains and slopes (Barkworth in FNA 2007).
