State Rank Reason (see State Rank above)
Pyrrocoma lanceolata is widely scattered from southwest to northeast Montana. It grows in moist to wet meadows in the plains, valleys, and montane areas. In southwest Montana plants appear to share characteristics with P. uniflora plants. More information on this plant's locations, population sizes, and threats are needed.
