(see State Rank Reason below)
MNPS Threat Rank
State Rank Reason (see State Rank above)
Between 1902 and 2016 Piperia elegans has been observed at 202 locations in northwest Montana. Populations seem to be common and tolerant of some disturbances, such as from grazing and logging.

Inflorescence: An often crowded, spikelike raceme (Douglas et al. 2001), 9–30 cm in length; bracts 5–8 mm in length (Lesica 2012).(Lesica’s contribution adapted from Lesica 2012. Manual of Montana Vascular Plants. BRIT Press. Fort Worth, TX.)
