State Rank Reason (see State Rank above)
Echinocystis lobata occurs sporadically in the western U.S. (FNA 2015). In Montana it has been collected in the southwestern, south-central, and southeastern areas along creek bottoms and canals, on fences, in gardens, and along roads. Almost half of the known collections were documented from 1888 to 1965 with very imprecise locations. It appears to be tolerant of some disturbance though current population and location data is needed.
