Clintonia is a genus of flowering plants in the lily family Liliaceae. Plants of the genus are distributed across the temperate regions of North America and eastern Asia, in the mesic understory of deciduous or coniferous forests. The genus, first described by Constantine Samuel Rafinesque in 1818, was named for DeWitt Clinton (1769–1828), a naturalist and politician from the U.S. state of New York. For this reason, plants of the genus are commonly known as Clinton's lily. The common name bluebead refer to the distinctive fruit of members of the genus. Since fruit color varies somewhat across species, the common name bead lily is used as well.
The Coronado Islands are a group of islands located 13 km (8 mi) off the northwest coast of the Mexican state of Baja California. Battered by the wind and waves, the rocky islands are mostly uninhabited except for a small military detachment and a lighthouse keeper. Despite their barren appearance, they serve as a refuge for seabirds and support a sizable number of plants, including 6 endemic taxa found only on the islands. The waters around the islands support a considerable amount of diverse marine life.

A large, evergreen shrub in the heather family, this species is near-endemic to northwestern Baja California, with a small population just north of the border in San Ysidro, California. It produces a much-branched inflorescence of white, urn-shaped flowers, and has leathery leaves that appear opposite or in whorls. These characteristics separate it from its close relatives in the region, which include manzanitas (Arctostaphylos), summer holly (Comarostaphylis) and mission manzanita (Xylococcus).
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" 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. It is threatened in some localities by the development of its coastal habitat, which tends to be prime locations for high-end residential and commercial developments.
