About

Euphorbia misera is a semi-succulent shrub in the genus Euphorbia commonly known as the cliff spurge or coast spurge. A drought-deciduous shrub, it is typically found as a gnarled, straggly plant occupying seashore bluffs, hills and deserts. Like other members of its genus, it has a milky sap, which can be found exuding out of the light gray bark when damaged. The alternately-arranged leaves are round and folded in the middle, with small hairs on them. The "flowers" (actually an inflorescence called a cyathium) can be found blooming year-round, and are colored maroon or yellow in the center with 5 white to light-yellow petal-like appendages attached outside. This species is native to the Baja California peninsula and Sonora in Mexico, and the coast of Southern California in the United States, where it is a rare species.

Where it grows

This species is distributed across the Baja California peninsula (the states of Baja California, Baja California Sur) and parts of Sonora in Mexico, and the coast of Southern California in the United States. On the Baja California peninsula, this species is a common and widespread shrub found from the vicinity of Tijuana in northwest Baja California south to the southern Sierra de la Giganta in Baja California Sur, along with adjacent Pacific and Gulf of California islands. Plants found on the San Benito Islands have sometimes been regarded as their own species, Euphorbia benedicta, based on their larger gland appendages and seeds. In Sonora, this species is found on the Gulf coast. In California, this species can be found on coastal bluffs and mesas from Corona Del Mar in Orange County to the international border in San Diego County, along with Santa Cruz, Santa Catalina, and San Clemente islands. A disjunct population is found in the Coachella Valley of Riverside County.
