Brassicaceae or Cruciferae is a medium-sized and economically important family of flowering plants commonly known as the mustards, the crucifers, or the cabbage family. Most are herbaceous plants, while some are shrubs. The leaves are simple, lack stipules, and appear alternately on stems or in rosettes. The inflorescences are terminal and lack bracts. The flowers have four free sepals, four free alternating petals, two shorter free stamens and four longer free stamens. The fruit has seeds in rows, divided by a thin wall.

The genus Cheiranthus is sometimes included here in whole or in part. Erysimum has since the early 21st century been ascribed to a monogeneric cruciferous tribe, Erysimeae, characterised by sessile, stellate (star-shaped) and/or malpighiaceous (two-sided) trichomes, yellow to orange flowers and multiseeded siliques.

Erysimum nevadense is a perennial short-lived herb endemic to the Sierra Nevada of Spain, although there are some citations in the nearby Sierra de Gádor (Almería). This wallflower occurs between 1,700 and 2,700 m above sea level in subalpine scrublands and alpine meadows. It may be treated as a narrowly circumscribed single species, one of a group or complex of six separate species, or as a more broadly circumscribed species with six subspecies.
Apodemia mormo langei, the Lange's metalmark butterfly, is an endangered North American butterfly. It is a subspecies of the Mormon metalmark and belongs to the family Riodinidae. The butterfly is endemic to California, where it is known from one strip of riverbank in the San Francisco Bay Area. A 2008 count estimated the total remaining population at 131 individuals. Since 2011, this number has dropped to about 25–30.
Erysimum capitatum is a species of wallflower known commonly as the sanddune wallflower, western wallflower, or prairie rocket.
Erysimum cheiranthoides, the treacle-mustard,wormseed wallflower, or wormseed mustard is a species of Erysimum native to most of central and northern Europe and northern and central Asia. Like other Erysimum species, E. cheiranthoides accumulates two major classes of defensive chemicals: glucosinolates and cardiac glycosides.
Erysimum ammophilum is a species of wallflower known by the common name coast wallflower.
Erysimum cheiri, syn. Cheiranthus cheiri, the wallflower, is a species of flowering plant in the family Brassicaceae (Cruciferae), native to Greece, but widespread as an introduced species elsewhere. It is also treated as a hybrid under the name Erysimum × cheiri. It is widely cultivated as a garden plant.

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.
Coincya monensis is a plant species in the family Brassicaceae. Coincya monensis is native to western Europe and Morocco, but has been introduced in North America.
Erysimum scoparium is a species of flowering plant in the family Brassicaceae, native to the Canary Islands. It is a shrubby species of wallflower with purplish flowers found at high altitudes.
Erysimum crepidifolium, the pale wallflower, is a plant species in the crucifer family, Brassicaceae. It is a member of the genus Erysimum, which includes between 150 and 350 species in the Northern Hemisphere.
Physaria ludoviciana is a species of flowering plant in the mustard family Brassicaceae, with the common names of bladder pod, silver bladderpod, louisiana bladderpod, and foothill bladderpod. It used to be Lesquerella ludoviciana which is now a synonym.
Erysimum merxmuelleri is a biennial or short-lived perennial plant native from eastern Portugal to western Spain. It has been treated as one of a complex of six species making up the nevadense group, or as Erysimum nevadense subsp. merxmuelleri.
Erysimum deflexum, the bent treacle mustard, is a herbaceous plant, a member of the family Brassicaceae.
Arabis allionii is a species of flowering plant in the family Brassicaceae, native to the mountains of central and southern Europe and southern Turkey. The Royal Horticultural Society lists it as a garden plant for attracting pollinators, but gives its common name as "Siberian wallflower", suggesting that they have it confused with Erysimum × marshallii.
