A samara is a winged achene, a type of fruit in which a flattened wing of fibrous, papery tissue develops from the ovary wall. A samara is a simple dry fruit, and is indehiscent. The shape of a samara enables the wind to carry the seed farther away from the tree than regular seeds would go, and is thus a form of anemochory.
Ptelea trifoliata, commonly known as common hoptree, wafer ash, stinking ash, and skunk bush, is a species of flowering plant in the citrus family (Rutaceae). It is native to North America, where it is found in Canada, Mexico, and the United States. It is a deciduous shrub or tree, with alternate, trifoliate leaves.
Ptelea is a genus of flowering plants in the citrus family, Rutaceae. The name, of Greek derivation, is the classical name of the elm tree. Carl Linnaeus used that word for this genus because of the resemblance of its fruit to that of the elm. Members of the genus are commonly known as hoptrees.

Grusonia is a genus of opuntioid cacti, originating from the North American Deserts in Southwest United States and northern Mexico, including Baja California. Authors differ on precise boundaries of the genus, which has been included in Cylindropuntia. Corynopuntia, also known as club chollas, is now a synonym, with the genus originally being described by Knuth in 1935. Molecular phylogenetic studies suggest that it should be included in Grusonia, a view accepted by Plants of the World Online as of June 2021.

Ornithostaphylos is a monotypic plant genus which contains the single species Ornithostaphylos oppositifolia, commonly known as the Baja California birdbush or Baja California manzanita. 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).
Deinandra is a genus of flowering plants in the tribe Madieae within the family Asteraceae. Such a genus is not recognized as distinct by all authorities; its species are often treated as members of the genus Hemizonia.
Zizia is a genus of flowering plants in the parsley family, Apiaceae. It was named after Johann Baptist Ziz (1779–1829), a German botanist from the Rhineland. It is native to North America.
Zizia aptera is a flowering plant native to North America. Its common names include meadow zizia, golden alexanders, heart leaved golden alexanders, and prairie golden alexanders.
Dodonaea aptera, commonly known as coast hop-bush, is a species of coastal shrub endemic to Western Australia.
Nemacladus is a genus of flowering plants in the bellflower family known generally as threadplants. Species are native to the southwestern United States and northern Mexico. These are annual herbs with very slender, sometimes threadlike, branching stems bearing small five-lobed flowers.

Ptelea crenulata, commonly known as the California hoptree, is a species of tree that is endemic to the state of California in the United States. It is found in the western Sierra Nevada and southern Cascade Range foothills, the northern California Coast Ranges, and the San Francisco Bay Area.
Gambelia is a genus of flowering plants in the Antirrhineae tribe of the plantain family commonly known as bush snapdragons. This genus is native to northwestern Mexico, particularly the Baja California Peninsula, but species are also found on the coast of Sonora, Guadalupe Island, and the Channel Islands of California. The genus is named in honor of William Gambel (1823–1849), an American naturalist, ornithologist, and botanist.
