State Rank Reason (see State Rank above)
Artemisia rigida is not documented in Montana. Artemisia rigida was included in the Vascular Plants of the Pacific Northwest - Volume 5 (Cronquist 1955). This was the basis for its inclusion in the Vascular Plants of Montana (Dorn 1984). Artemisia rigida was also included in a sagebrush guidebook produced by Montana Fish, Wildlife & Parks (date unknown). In the Flora of North America Montana is included in the distribution of Artemisia rigida; yet, the basis for this report is unknown (Shultz in Flora of North America 2006). Extensive searches for plant specimens or reported observations have turned up nothing (Lesica et al. 2012; MTNHP Status Review in 2018). A conservation status rank is not applicable (SNA) because this plant is not known to occur in Montana.
