''Orcuttia inaequalis'' is a rare species of grass known by the common name San Joaquin Valley Orcutt grass. ==Distribution== It is endemic to the Central Valley of California, where it grows only in vernal pools, a rare and declining type of habitat. Many known occurrences of the plant have been extirpated as land in the heavily agricultural Central Valley has been altered, and it was federally listed as a threatened species in 1997.〔USFWS. (Determination of endangered status for three plants and threatened status for five plants from vernal pools in the Central Valley of California ). ''Federal Register'' March 26, 1997.〕
