Deinandra minthornii — (syn. Hemizonia minthornii) — is a species of flowering plant in the aster family known by the common name Santa Susana tarplant, or Santa Susana tarweed. It is an endangered species, listed as a Threatened species by the California Department of Fish and Game,[1] as Imperiled under the California Endangered Species Act—CESA,[2] and on the California Native Plant Society—CNPS Inventory of Rare and Endangered Plants.[2]

Distribution

Deinandra minthornii (Hemizonia minthornii) is endemic from the Santa Susana Mountains, through the Simi Hills, to the Santa Monica Mountains of the southwestern Transverse Ranges, in Los Angeles and Ventura Counties, Southern California.[3][4][5]

This plant grows in the coastal sage scrub and chaparral habitats of the coastal sage and chaparral, and the chaparral habitat of the adjacent inland the montane chaparral and woodlands. It can be found on rocky outcroppings and in sandstone crevices, from 300–500 metres (980–1,640 ft) in elevation.[3][5] There are about 20 occurrences of the plant, but several have not been observed recently.[4]
