Clarkia biloba is a species of flowering plant in the evening primrose family known by the common name twolobe clarkia and two lobed clarkia.[1]
Clarkia biloba is endemic to California, where it is known from the Sierra Nevada foothills; one subspecies can also be found in the San Francisco Bay Area. It grows in chaparral, oak woodlands, and yellow pine forest habitats.[1]
As the putative progenitor species of Clarkia lingulata it is often used in examples of evolution outside the usual model of allopatric speciation.[2] As such this plant is one of the best plant examples when considering "quantum speciation," a concept closely aligned with peripatric speciation, parapatric speciation and sympatric speciation.
