Chylismia claviformis is a species of wildflower known as browneyes or brown-eyed primrose. It is an annual plant growing from a basal rosette of long oval leaves and producing stems often exceeding half a meter in height. Atop the stem is an inflorescence of one to many primrose blooms, each with four white or yellow petals. The pistil may be quite long and has a bulbous stigma at the tip. The stamens are somewhat shorter and they bear long hairy anthers containing white or yellow pollen. The floral axis at the junction of male and female parts is bright red to maroon or brown. This species is found across western North America from the Pacific Northwest to northern Mexico.
The upright stems of chylismia claviformis are topped by a one-sided cluster of nodding white or pale yellow flowers, brown at the center, hence the common name of brown-eyed primrose. Flowers are formed of four pointed green sepals, often angled fully backwards, close to the pedicel, and four round white petals, which wither to deep pink. At the center are eight white stamens, the hairy anthers attached at their midpoint, and a longer style, holding a spherical stigma. The reddish-brown color comes from the inside of the floral tube.
Leaves are long, up to 8 inches, and irregularly divided into a dozen or more pairs of uneven, sometimes toothed lobes, the largest at the apex. They are produced mostly around the base. The main flowering period in spring is sometimes followed by a second blooming in the fall. There are eleven subspecies of chylismia claviformis, many with distinct ranges, differing in hairiness, petal color, glandularity, and leaf characteristics.
