General information

Phacelia argylensis, commonly named Argyle Canyon phacelia, is endemic to Argyle Canyon in Duchesne County, Utah. It grows in sandy-silty soil of washes in Green River Shale formation among pinyon-juniper, serviceberry, and Douglas Fir community at 7,595 feet elevation. In a 2018  Spring UNHP Survey, only 51 individuals were counted. In the summer of 2018, a flood occurred and wiped out all remaining individuals. Some observations have been made since then, however this species remains highly threatened by residential development, a potential railway-train route, and site erosion caused by fires.
