Clarkia lingulata

Clarkia lingulata is a rare species of wildflower known by the common name Merced clarkia. This plant is endemic to Mariposa County, California, where it is known from only two sites near the Merced River.
It is thought to have evolved very rapidly, outside the usual model of allopatric speciation, from its parental species "Clarkia biloba".
It is a state-listed endangered species in California.
