| Erigeron parishii | |
Erigeron parishii is a species of flowering plant in the family Asteraceae known by the common names Parish's daisy and Parish's fleabane. [1] [2]
Erigeron parishii is native to San Bernardino County and Riverside County in southern California. [3] [2] It is a federally-listed threatened species losing habitat to development and the limestone mining industry on the north slope of the San Bernardino Mountains.
Erigeron parishii is a small perennial herb reaching a maximum height of about 30 centimeters (12 inches). The taproot can penetrate the carbonate soils to a depth of 50 cm (19.5 in). [4] Its stem and foliage are covered in silvery-white hairs and most of the leaves are basal and measure 3 to 6 centimeters (1.2 to 2.4 inches) long. [1]
The erect stems have inflorescences of one to ten flower heads, each between one and two centimeters (0.4-0.8 inches) wide. The flower head has a center of golden yellow disc florets and a fringe of up to 55 lavender, pink, or white ray florets. [1]
Erigeron parishii usually grows on limestone substrates, or granite topped with a layer of limestone. [5] It apparently requires very alkaline soils. [4] [1]
The same rock that the plant favors is also sought after for human use and limestone mining is the most significant threat to its habitat. [4]
Erigeron parishii has a relatively high genetic diversity for a narrow endemic, a measure that will decrease with the habitat fragmentation that currently threatens it. [6]

Erigeron petrophilus is a species of flowering plant in the family Asteraceae known by the common names rockloving erigeron or cliff fleabane. It is native to the mountain ranges of California from Siskiyou County south as far as San Luis Obispo County and El Dorado County. It also grows in southwestern Oregon.
Erigeron reductus is a species of flowering plant in the family Asteraceae known by the common name lesser California rayless fleabane. It is endemic to California, from Trinity County south as far as Alameda County and El Dorado County.
Erigeron sanctarum is an uncommon species of flowering plant in the family Asteraceae known by the common names saints fleabane and saints daisy. It is endemic to California, where it is known from San Luis Obispo and Santa Barbara Counties including two of the Channel Islands.
Erigeron supplex is a rare species of flowering plant in the family Asteraceae known by the common names supple daisy or supple fleabane. It grows along the coastline and in the Coast Ranges in California, north of San Francisco Bay. It probably remains only in Sonoma and Marin Counties. There is a report of it growing well inland in Shasta County, but this is from a farm and probably a cultivated specimen.
Erigeron tener is a North American species of flowering plant in the family Asteraceae known by the common name slender fleabane. It is native to the western United States, largely in the Great Basin, in the states of California, Arizona, Nevada, Utah, Oregon, Wyoming, Idaho, and Montana.
Erigeron maniopotamicus is a rare species of flowering plant in the family Asteraceae known by the common name Mad River fleabane. It is endemic to northwestern California, where it is known from only four locations in Humboldt and Trinity Counties.
Erigeron serpentinus is a rare species of flowering plant in the family Asteraceae known by the common names serpentine fleabane and serpentine daisy. It is endemic to Sonoma County, California, where it is known from three occurrences in and around The Cedars, in the Coast Ranges east of Salt Point and west of Healdsburg. There are an estimated 1100 individuals in existence. The Cedars is a canyon habitat with serpentine soils surrounded by non-serpentine terrain; it is home to several rare serpentine-endemic plant species. This daisy was discovered there and described to science in 1992.
Erigeron rhizomatus is a rare species of flowering plant in the family Asteraceae known by the common names Zuni fleabane and rhizome fleabane. It is native to western New Mexico and eastern Arizona in the United States. It is a federally listed threatened species.
