Layia leucopappa is a rare species of flowering plant in the family Asteraceae known by the common name Comanche Point tidytips, or Comanche Point layia.
The annual wildflower is endemic to California, where it is known only from the Tehachapi Mountains of southern Kern County in the vicinity of Tejon Ranch. Its distribution once extended onto the floor of the Central Valley, but it was eliminated from the area as the valley land was claimed for agriculture.
Layia leucopappa is an annual herb producing a light-colored, glandular stem to a maximum height just over 0.5 metres (1.6 ft). The leaves are fleshy and hairless except for ciliated edges. Smaller leaves are oval or oblong in shape and the larger ones are lobed and up to about 4 centimeters long.
The flower head contains white to cream-colored ray florets and yellow disc florets with yellow anthers.
The fruit is an achene; fruits from the disc florets are coated in white hairs and have a white pappus.
Layia platyglossa, commonly called coastal tidytips, is an annual wildflower of the family Asteraceae, native to western North America.
Blepharipappus is a North American plant genus in the family Asteraceae containing the single known species Blepharipappus scaber, known by the common name rough eyelash, or rough eyelashweed. Blepharis is Greek for 'eyelash' and 'pappus' refers to the feathery part of the plant's seeds.

Layia carnosa is a species of flowering plant in the family Asteraceae known by the common name beach tidytips, or beach layia. It is endemic to California, where it lives in beach habitat. It is known from several areas of mostly fragmented coastal habitat, and it was listed as an endangered species in California. On March 31, 2022, the category was changed from endangered species to threatened species by the US Department of the Interior Fish and Wildlife Service.
Layia chrysanthemoides is a species of flowering plant in the family Asteraceae known by the common name smooth tidytips, or smooth layia.
Layia discoidea is a rare species of flowering plant in the family Asteraceae known by the common name rayless tidytips, or rayless layia.
Layia fremontii is a species of flowering plant in the family Asteraceae known by the common name Frémont's tidytips. Both its common name, and its specific epithet are derived from John C. Frémont.
Layia gaillardioides is a species of flowering plant in the family Asteraceae known by the common name woodland tidytips.
Layia glandulosa is a species of flowering plant in the family Asteraceae known by the common names whitedaisy tidytips and white layia. It is native to western North America south from central Washington (state) to Baja California and east to Utah and Arizona, where it is common in a number of habitat types.
Layia heterotricha is a species of flowering plant in the family Asteraceae known by the common name pale yellow tidytips, or pale yellow layia.
Layia hieracioides is a species of flowering plant in the family Asteraceae known by the common name tall tidytips, or tall layia.
Layia jonesii is a species of flowering plant in the family Asteraceae known by the common name Jones' tidytips, or Jones' layia.

Layia septentrionalis is an uncommon species of flowering plant in the family Asteraceae known by the common name Colusa tidytips, or Colusa layia.
Calycadenia mollis is a species of flowering plant in the family Asteraceae known by the common name soft western rosinweed. It is native to a section of central California, from Tuolumne County do northern Tulare County. There are also isolated populations farther north in Nevada County.

Amauriopsis dissecta is a North American species of flowering plants in the daisy family known by the common names yellow ragweed and ragleaf bahia. It is native to the western United States as far north as the Black Hills of South Dakota and Wyoming, as well as in northern Mexico.
Felicia echinata, commonly known as the dune daisy or prickly felicia, is a species of shrub native to South Africa belonging to the daisy family. It grows to 1 m (3.3 ft) high and bears blue-purple flower heads with yellow central discs. In the wild, it flowers April to October.
Felicia is a genus of small shrubs, perennial or annual herbaceous plants, with 85 known species, that is assigned to the daisy family. Like in almost all Asteraceae, the individual flowers are 5-merous, small and clustered in typical heads, and which are surrounded by an involucre of, in this case between two and four whorls of, bracts. In Felicia, the centre of the head is taken by yellow, seldom whitish or blackish blue disc florets, and is almost always surrounded by one single whorl of mostly purple, sometimes blue, pink, white or yellow ligulate florets and rarely ligulate florets are absent. These florets sit on a common base and are not individually subtended by a bract. Most species occur in the Cape Floristic Region, which is most probably the area where the genus originates and had most of its development. Some species can be found in the eastern half of Africa up to Sudan and the south-western Arabian peninsula, while on the west coast species can be found from the Cape to Angola and one species having outposts on the Cameroon-Nigeria border and central Nigeria. Some species of Felicia are cultivated as ornamentals and several hybrids have been developed for that purpose.
