Clarkia lingulata

Clarkia lingulata is a rare species of wildflower known by the common name Merced clarkia. This plant is endemic to Mariposa County, California, where it is known from only two sites near the Merced River.

Contents

It is thought to have evolved very rapidly, outside the usual model of allopatric speciation, from its parental species Clarkia biloba . [1]

It is a state-listed endangered species in California. [2]

Description

Clarkia lingulata erects a spindly stem rarely exceeding 0.5 metres (1.6 ft) in height and bearing sparse narrow leaves.

The saucer-shaped flowers have four bright pink spoon-shaped petals 1 to 2 centimeters long and sometimes flecked with red. There are eight stamens with lavender anthers.

<span class="mw-page-title-main">Peripatric speciation</span> Speciation in which a new species is formed from an isolated smaller peripheral population

Peripatric speciation is a mode of speciation in which a new species is formed from an isolated peripheral population. Since peripatric speciation resembles allopatric speciation, in that populations are isolated and prevented from exchanging genes, it can often be difficult to distinguish between them. Nevertheless, the primary characteristic of peripatric speciation proposes that one of the populations is much smaller than the other. The terms peripatric and peripatry are often used in biogeography, referring to organisms whose ranges are closely adjacent but do not overlap, being separated where these organisms do not occur—for example on an oceanic island compared to the mainland. Such organisms are usually closely related ; their distribution being the result of peripatric speciation.

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 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.

<i>Clarkia delicata</i> Species of flowering plant

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.

<span class="mw-page-title-main">Harlan Lewis</span> American botanist

Frank Harlan Lewis was an American botanist, geneticist, taxonomist, systematist, and evolutionist who worked primarily with plants in the genus Clarkia. He is best known for his theories of "catastrophic selection" and "saltational speciation", which are closely aligned with the concepts of quantum evolution and sympatric speciation. The concepts were first articulated in 1958 by Lewis and Peter H. Raven, and later refined in a 1962 paper by Lewis in which he coined the term "catastrophic selection". In 1966, he referred to the same mechanism as "saltational speciation".
