State Rank Reason (see State Rank above)
Lappula cenchrusoides occurs in eastern Montana, and is being treated as a synonym of Lappula fremontii var. fremontii. Many populations were reported as common and as occurring in habitats that are common within Montana, such as clay soils in rolling grassland and in sagebrush steppe. Most Montana occurrences have been reported since 1973 which could reflect taxonomy more than its presence/absence. The taxonomy of Montana's specimens need to be clarified and more current information on locations, population sizes, habitat, and threats needs to be brought forth to further refine its status.

The two rows of bristles (sometimes 3) on the nutlets are similar to L. squarrosa, but the latter has a longer corolla (2-3 mm) and shorter nutlets (3-4 mm long). Lappula occidentalis (often reported as L. redowskii) only has one row of bristles on the nutlets.
Known (2012) in ND and SD west of the MO River, nealy all of WY, and northeast UT (Rocky Mountain Herbarium website).
