About Clarkia delicata (Abrams) A.Nelson & J.F.Macbr.
Clarkia delicata (Abrams) A.Nelson & J.F.Macbr. is a rare species of flowering plant in the evening primrose family. It has two common names: Campo clarkia and delicate clarkia. This plant is native to northern Baja California and the adjacent area of San Diego County, California, where it grows in woodland and chaparral habitats of the Peninsular Ranges. It is an annual herb that grows an erect stem reaching a maximum height of just over half a meter. Its leaves are oval or widely lance-shaped, grow up to 4 centimeters long, and are attached to the stem by very short petioles. An inflorescence occupies the top of the stem: lower flowers in the cluster open while upper buds remain closed. When the flower blooms, the sepals stay fused, and the flower emerges from one side of this fused structure. Each unlobed oval petal is about a centimeter long and ranges in color from pink to pinkish-lavender. The flower has 8 stamens: some have large orange anthers, and others have smaller, paler anthers. It also has a protruding stigma that bears four large, fuzzy lobes.
