Hickman's potentilla

Hickman’s potentilla (Potentilla hickmanii) is an endangered perennial herb of the rose family. This rare plant species is found in a narrowly restricted range in coastal northern California, primarily along a confined location of northern Monterey County, secondarily in extremely small colonies in San Mateo County and Sonoma County. This small wildflower, endemic to western slopes of the outer coastal range along the Pacific Ocean coast , produces bright yellow blossoms throughout the spring. The species is also known by the common name Hickman's cinquefoil.

This plant, along with many other threatened species in the northern California Floristic Province, has been designated as a species meriting protection by the U.S. Government, State of California, local governments and private conservation groups. These designations have led to blueprints for protection of Hickman's potentilla in the form of official endangerment classifications and a species Recovery Plan, the latter promulgated by the U.S. Environmental Protection Agency. Even with all these efforts, the total current population is estimated to be fewer than 4500 organisms.citation needed]
