Clarkia lewisii is an uncommon species of flowering plant in the evening primrose family known by the common name Lewis' clarkia. It is endemic to California, where it is known from the hills and mountains of Monterey and San Benito Counties.
It is an erect annual herb generally under half a meter in height. The lance-shaped leaves are a few centimeters long have petioles shorter than 7 mm, with blades 2-5 cm long.. The inflorescence bears opening flowers and closed, hanging flower buds. The flower's tube measures 1.5-4 mm and has a ring of hairs at the rim. As the bud opens the pink or purple sepals stay fused as the petals bloom from one side. The fan-shaped petals are up to 3 centimeters long, pink to lavender with white and red coloration near the bases. There are 8 stamens and a protruding stigma. The ovary is four-grooved, with the stigma extending beyond the anthers. The fruit is cylindrical, measuring 1.5-7 cm. [1]
Clarkia unguiculata is a species of wildflower known by the common name elegant clarkia or mountain garland. This plant is endemic to California, where it is found in many woodland habitats. Specifically it is common on the forest floor of many oak woodlands, along with typical understory wildflowers that include Calochortus luteus, Cynoglossum grande and Delphinium variegatum. C. unguiculata presents a spindly, hairless, waxy stem not exceeding a meter in height and bears occasional narrow leaves. The showy flowers have hairy, fused sepals forming a cup beneath the corolla, and four petals each one to 2.5 centimeters long. The paddle-like petals are a shade of pink to reddish to purple and are slender and diamond-shaped or triangular. There are eight long stamens, the outer four of which have large red anthers. The stigma protrudes from the flower and can be quite large. Flowers of the genus Clarkia are primarily pollinated by specialist bees found in their native habitat "Clarkias independently developed self-pollination in 12 lineages."
Clarkia davyi is a species of flowering plant in the evening primrose family known by the common name Davy's fairyfan, or Davy's clarkia. It is endemic to California, where it grows in coastal habitats such as beaches and bluffs. This is an annual herb producing a thin stem which grows along the ground or somewhat upright. It is lined with small oval-shaped leaves one or two centimeters long. While in bud the flower is enclosed in four fused thick sepals. It blooms into a petite bowl-shaped corolla of four pink petals which often have lighter bases. Each petal is 5 to 11 millimeters long.

Clarkia australis is a species of flowering plant in the evening primrose family known by the common name Small's southern clarkia. It is endemic to California, where it grows in the forests of the central Sierra Nevada. It is an uncommon species threatened by such forest activities as logging. This annual herb produces a slender, erect stem approaching a meter in height. The leaves are widely linear in shape and borne on short petioles. The top of the stem is occupied by the tall inflorescence, which bears hanging buds that open from the lowest upward so that there are several closed buds above open flowers. The sepals do not remain fused as the flower opens. The petals are diamond-shaped and sometimes lobed and curling at the tip. They are mottled or spotted lavender, purple, and reddish in color, and each is up to 1.5 centimeters long. There are 8 long stamens tipped with large anthers bearing blue-gray pollen. The stigma protrudes past the anthers.

It is endemic to California, where it is known from the forests of the southern Klamath Range and the southernmost Cascade Range foothills. It is an annual herb growing an erect, slender stem. The leaves are oval in shape and borne on short petioles. The top of the stem is occupied by the inflorescence, in which the lowest flowers open first and hanging, pointed flower buds occur at nodes at the top. The sepals separate as the flower blooms, revealing purplish pink petals. Each petal is between 1 and two centimeters long, elongated triangular to semicircular in shape, and sometimes flecked with dark purple. There are 8 stamens with anthers bearing blue-gray pollen, and a protruding stigma.

It is native to northern Baja California and adjacent San Diego County, California, where it grows in the woodland and chaparral of the Peninsular Ranges. This is an annual herb producing an erect stem just over half a meter in maximum height. The leaves are oval or widely lance-shaped, up to 4 centimeters long, and borne on very short petioles. The top of the stem is occupied by the inflorescence, in which the lower flowers open while the upper buds hang closed. The sepals remain fused as the flower blooms from one side. Each unlobed oval petal is about a centimeter long and pink to pinkish-lavender. There are 8 stamens, some with large orange anthers and some with smaller, paler anthers. There is also a protruding stigma with four large, fuzzy lobes.
Clarkia dudleyana is a species of flowering plant in the evening primrose family known by the common name Dudley's clarkia. It is endemic to California, where it can be found in the mountains of the Transverse Ranges and the southern Sierra Nevada foothills. It grows in woodland, forest, and chaparral habitats under 1500 meters in elevation. This annual herb produces an erect stem sometimes exceeding half a meter in height. The leaves are lance-shaped, up to 7 centimeters long, and borne on short petioles. The top of the stem is occupied by the inflorescence, which has opening flowers below closed, hanging buds. As the flower blooms the pink to reddish-purple sepals remain fused, opening along one side only. The petals are up to 3 centimeters long, fan-shaped, pinkish lavender in color and sometimes flecked with red. There are 8 stamens, some of which have large lavender anthers and some that have smaller, paler anthers. The stigma protrudes farther than the stamens.
Clarkia epilobioides is a species of flowering plant in the evening primrose family known by the common name canyon clarkia. It is native to California, Arizona, and Baja California, where it grows in shaded habitat in woodland and chaparral. It is an annual herb producing a slender, erect stem sometimes exceeding half a meter in height. The leaves are narrowly to widely lance-shaped and less than 3 centimeters long. The top of the stem is occupied by the inflorescence. Each hanging bud has four red sepals which remain fused all together or in pairs as the petals emerge during blooming. The petals are one half to one centimeter long, oval in shape, solid white or cream in color, often fading pink as they age. There are eight protruding stamens and one stigma.
