Clarkia jolonensis is an uncommon species of flowering plant in the evening primrose family known by the common name Jolon clarkia. It is endemic to Monterey County, California, where it is known from the woodlands of the Central Coast Ranges.
This is an erect annual herb growing a hairless, waxy stem up to about half a meter in maximum height. The leaves are lance-shaped and a few centimeters long. The top of the stem is occupied by an erect inflorescence with opening flowers below an erect array of closed, hanging flower buds. The sepals of the bud remain fused as it opens into a bloom. The fan-shaped lavender petals are often flecked with red and tinted with pink, each measuring one or two centimeters long. There are 8 stamens, some of which have large lavender anthers, and some bearing smaller, paler anthers.
This plant is very similar to, and historically confused with, Clarkia lewisii , which differs from C. jolonensis in that the former has a curved inflorescence with closely packed nodding flower buds, while the latter has an erect, widely spaced inflorescence. [2] Some of the few known occurrences of this plant may actually be its sister species, making it rarer than officially listed. [2]
Clarkia gracilis is a species of wildflower known by the common name slender clarkia. This plant is native to the US states of California, Oregon, and Washington, where it is found in coastal, foothill, valley, and low-elevation mountain habitats. The plant is variable across subspecies but is generally an erect slender stem with a few sparse, narrow leaves several centimeters long. It bears an inflorescence of drooping buds which open into bowl-shaped flowers with pinkish lavender petals 1 to 4 centimeters long and bearing a red or white splotch which can appear in the center or at the base of the petal, depending on the subspecies.
Clarkia cylindrica is a species of flowering plant in the evening primrose family known by the common name speckled fairyfan, or speckled clarkia.
Clarkia arcuata is a species of flowering plant in the evening primrose family known by the common name glandular clarkia. It is endemic to California, where it grows in the chaparral and woodlands of the foothills of the Sierra Nevada and southern Cascade Range. It is an annual herb producing a slender, erect stem often exceeding half a meter in height. The leaves are narrow, usually linear or lance-shaped, and up to 6 centimeters long. The inflorescence bears a few flowers, which dangle when they are buds and grow erect as they open. The sepals stay fused as the petals open and emerge from one side. They are coated in glandular hairs. The petals are up to 3 centimeters long, pink-lavender in color, sometimes with a reddish blotch at the base. They form a bowl-shaped corolla. There are 8 stamens and a protruding, four-chambered ovary. The fruit is an elongated capsule which may reach 3.5 centimeters 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.
Clarkia biloba is a species of flowering plant in the evening primrose family known by the common name twolobe clarkia and two lobed clarkia.
Clarkia borealis is a rare species of flowering plant in the evening primrose family known by the common name northern clarkia. 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.
Clarkia delicata is a rare species of flowering plant in the evening primrose family known by the common names Campo clarkia and delicate clarkia. 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 exilis is a small herbaceous annual plant of western North America. It is an uncommon species in the evening primrose family known by the common names Kern River clarkia and slender clarkia.
Clarkia franciscana is a rare species of flowering plant in the evening primrose family known by the common name Presidio clarkia. It is endemic to the San Francisco Bay Area of California, where it is known only from two populations at the Presidio of San Francisco and three occurrences in Oakland. The plant is known only from serpentine soils.
Clarkia heterandra is a species of flowering plant in the evening primrose family known by the common name mountain clarkia. It is endemic to California, where it is from the forests and woodlands of several of eastern and western mountain ranges.
