Erysimum, or wallflower, is a genus of flowering plants in the cabbage family, Brassicaceae. It includes more than 150 species, both popular garden plants and many wild forms. Erysimum is characterised by star-shaped and/or two-sided) trichomes growing from the stem, with yellow, red, pink or orange flowers and multiseeded seed pods.
Eriogonum is a genus of flowering plants in the family Polygonaceae. The genus is found in North America and is known as wild buckwheat. This is a highly species-rich genus, and indications are that active speciation is continuing. It includes some common wildflowers such as the California buckwheat.
Apodemia mormo is a principally Nearctic butterfly in the family Riodinidae. It is a particularly fascinating species for ecological and evolutionary research, as evidenced by its shifting taxonomic classifications. Conflicting observations of host plants utilized, distinctive morphologies, and a wide range of occupied habitats have prompted investigation into several potential subspecies. To date, two genetic studies have been done on A. mormo, with analysis revealing that disjunct populations are genetically and phenotypically distinct. These studies support a potential need for refined taxonomies, although a larger body of data is required to make clear decisions.
Eriogonum nudum is a perennial shrub of the wild buckwheat genus which is known by the common name naked buckwheat or nude buckwheat.
The Delhi Sands flower-loving fly is a subspecies of flower-loving fly, a member of the genus Rhaphiomidas in the family Mydidae. It was the first fly added to the Endangered Species List in the United States.
Eriogonum fasciculatum is a species of wild buckwheat known by the common names California buckwheat and flat-topped buckwheat. Characterized by small, white and pink flower clusters that give off a cottony effect, this species grows variably from a patchy mat to a wide shrub, with the flowers turning a rusty color after blooming. This plant is of great benefit across its various habitats, providing an important food resource for a diversity of insect and mammal species. It also provides numerous ecosystem services for humans, including erosion control, post-fire mitigation, increases in crop yields when planted in hedgerows, and high habitat restoration value.
Smith's blue butterfly, Euphilotes enoptes smithi, is a subspecies of butterfly in the family Lycaenidae. This federally listed endangered subspecies of Euphilotes enoptes occurs in fragmented populations along the Central Coast of California, primarily associated with sand dune habitat in one case with a dune-based Maritime Coast Range Ponderosa Pine forest in the Carbonera Creek watershed in Santa Cruz County. The range of E. e. smithi is from Monterey Bay south to Punta Gorda.
The Sand Mountain blue is a lycaenid butterfly of the "blue" subfamily that is only found around the Sand Mountain Recreation Area near Fallon, Nevada. It is a subspecies of the pallid blue.
Myrtle's silverspot is a medium-sized butterfly in the brush foot family (Nymphalidae), an endangered subspecies of the zerene fritillary. It is endemic to California, where it is known from only about four locations just north of the San Francisco Bay Area, including two at Point Reyes National Seashore. Its wingspan is approximately 2.2 inches (56 mm). The upper surfaces of the wings are golden brown with numerous black spots and lines. The undersides are brown, orange and tan with black lines and silver and black spots. Larvae are dark colored with many sharp branching spines on their backs. Myrtle's silverspot is larger and paler than the closely related Behrens' silverspot, which is now limited to the vicinity of Point Arena in Mendocino County. Myrtle's silverspot is also closely related to the Oregon silverspot.
Erysimum capitatum is a species of wallflower known commonly as the sanddune wallflower, western wallflower, or prairie rocket.
Oenothera deltoides is a species of evening primrose known by several common names, including birdcage evening primrose, basket evening primrose, lion in a cage, and devil's lantern. It is native to the Southwestern United States and northern Mexico, where it grows in sandy habitats from desert to beach.
Antioch Dunes National Wildlife Refuge is a sensitive sand dune habitat located near the city of Antioch, California on the south shore of the San Joaquin River-Stockton Deepwater Shipping Channel. It serves as a refuge for three endangered species of plants and insects, and is closed to the public except for tours and events supervised by Refuge staff. The Refuge was established in 1980. It is managed by the U.S. Fish and Wildlife Service.
Chorizanthe howellii is a species of flowering plant in the buckwheat family known by the common names Mendocino spineflower and Howell's spineflower. It is endemic to coastal Mendocino County, California, where it is known only from the sand dunes and coastal scrub near Fort Bragg. It is estimated that 95% of the remaining individuals of this plant are part of a single population growing at MacKerricher State Park. It is a federally listed endangered species.
Eriogonum kennedyi is a species of wild buckwheat known by the common name Kennedy's buckwheat.
The Bonny Doon Ecological Reserve is a nature preserve of 552 acres (2.23 km2) in the Santa Cruz Mountains of California, United States. The reserve protects several rare and endangered plant and animal species within an area known as the Santa Cruz Sandhills, an ancient seabed containing fossilized marine animals.
The white flower moth is a moth of the family Noctuidae found in the United States and Canada. It is designated as Endangered under Canada's Species At Risk Act and Manitoba's Endangered Species and Ecosystems Act.
Oenothera deltoides subsp. howellii, the Antioch Dunes evening primrose, is an endangered subspecies of plant in the family Onagraceae, genus Oenothera, and species Oenothera deltoides.
Oenothera californica, known by the common name California evening primrose, is a species of flowering plant in the evening primrose family.
Eriogonum elongatum, commonly known as longstem buckwheat or wand buckwheat, is a species of wild buckwheat native to coastal southern and Baja California.
