Penstemon, the beardtongues, is a large genus of roughly 280 species of flowering plants native mostly to the Nearctic, but with a few species also found in the North American portion of the Neotropics. It is the largest genus of flowering plants endemic to North America. As well as being the scientific name, penstemon is also widely used as a common name for all Penstemon species alongside beardtongues.
Sphaeralcea is a genus of flowering plants in the mallow family (Malvaceae). There are about 40-60 species, including annuals, perennials, and shrubs. Most originate in the drier regions of North America, with some known from South America. They are commonly known as globemallows, globe mallows, false mallows or falsemallows. The name of the genus is derived from the Greek words σφαῖρα (sphaira), meaning "sphere," and αλκεα (alkea), meaning "mallow."
Cercocarpus, commonly known as mountain mahogany, is a small genus of at least nine species of nitrogen-fixing flowering plants in the rose family, Rosaceae.

Several are found in the California chaparral and woodlands ecoregion.

Packera is a genus of about 75 species of plants in the daisy family, Asteraceae. Most species are commonly called ragworts or grounsels. Its members were previously included in the genus Senecio, but were moved to a different genus based on chromosome numbers, a variety of morphological characters, and molecular phylogenetic evidence.
Dalea is a genus of flowering plants in the legume family, Fabaceae. Members of the genus are commonly known as prairie clover or indigo bush. Its name honors English apothecary Samuel Dale (1659–1739). They are native to the Western hemisphere, where they are distributed from Canada to Argentina. Nearly half of the known species are endemic to Mexico. Two species of Dalea have been considered for rangeland restoration.

Psorothamnus is a genus of plants in the legume family. These are shrubs and small trees. Many are known by the general common name indigo bush. Some are referred to as daleas, as this genus was once included in genus Dalea. These are generally thorny, thickly branched, strongly scented bushes. Most species bear lupinlike raceme inflorescences of bright purple legume flowers and gland-rich pods. Psorothamnus species are native to the southwestern United States and northern Mexico. The genus is paraphyletic and it has been proposed that the genus Psorodendron be reinstated to accommodate sections Xylodalea, Capnodendron, and Winnemucca.
Astragalus lentiginosus is a species of legume native to western North America where it grows in a range of habitats. Common names include spotted locoweed and freckled milkvetch. There are a great number of wild varieties. The flower and the fruit of an individual plant are generally needed to identify the specific variety.
Diphysa is a genus of flowering plants in the legume family, Fabaceae. It belongs to the subfamily Faboideae, and was recently assigned to the informal monophyletic Dalbergia clade of the Dalbergieae. It includes 22 species which range from Arizona through Mexico and Central America to Colombia and Venezuela.
Glaucocarpum is a monotypic plant genus containing the single species Glaucocarpum suffrutescens, a rare species of flowering plant in the mustard family known by the common names toad-flax cress, shrubby reed-mustard, Uinta Basin waxfruit and waxfruit mustard. It is endemic to Utah in the United States, where it is known only from Duchesne and Uintah Counties. It is threatened by habitat degradation and destruction. It is federally listed as an endangered species of the United States.
Eriocoma is a genus of plants in the grass family (Poaceae). It includes 27 species of grasses native to western and central North America. Species range from Alaska through western and central Canada, western and central United States, to northern Mexico.
Smelowskia, sometimes called false candytufts, is a genus of flowering plants in the crucifer family Brassicaceae, native to mountains and arctic regions of Asia and western North America. They may or may not be of Beringian origin.
Conimitella is a genus of flowering plants belonging to the family Saxifragaceae.
