State Rank Reason (see State Rank above)
Euthamia graminifolia is not documented as occurring in Montana. This plant has a long history of being 'reported' for Montana, but as of 2019 no specimens have been validated. The Flora of Montana (Booth 1966) included it, but with no Montana location. Euthamia graminifolia var. major was mapped as occurring in Rosebud County, Montana (McGregor et al. 1977), but the specimen was latter annotated to be Euthamia occidentalis (Caleb Morse personal communication). The Vascular Plants of Montana (Dorn 1984) and Flora of the Great Plains (McGregor et al. 1986) state it is "reported" and "reputedly in Rocky Mts. to NM", respectively, based on past information that lacked specimens. In the Flora of North America (FNA), Montana is included in the distribution of Euthamia graminifolia (Haines in FNA 2006); however, this was in error as the author did not attribute Montana to the range of this species (Arthur Haines personal communication). Subsequently, the range used in the FNA treatment was used in the 2nd Edition of the Flora of the Pacific Northwest (David Giblin personal communication). A NY Herbarium specimen collected in 2011 was mis-identified and represents Chrysothamnus viscidiflorus (Arthur Haines and Ben Legler personal communications). The closest verified specimen was collected in north Idaho and very near to the Montana border (Bjork 2002-ID 121824/145729). A conservation status rank is not applicable (SNA) because this plant is not known to occur in Montana.
