Phacelia crenulata is a species of flowering plant in the waterleaf family, Hydrophyllaceae. Its common names include notch-leaf scorpion-weed,[1] notch-leaved phacelia, cleftleaf wildheliotrope, and heliotrope phacelia.[2] Phacelia crenulata has an antitropical distribution, a type of disjunct distribution where a species exists at comparable latitudes on opposite sides of the equator, but not at the tropics. In North America, it is native to the southwestern United States as far east as Colorado and New Mexico, and Baja California and Sonora in Mexico.[3] In South America, it is native to southern Peru, western Bolivia, and northern Chile.[4][5]
