Chylismia claviformis subsp. claviformis
Family: Onagraceae · Type: annual · Native
Evening primrose is a California native annual found in the Mojave Desert and its edges in creosote-bush scrub and alluvial slopes at elevations of 850 to 1,700 meters. Flowering from March to May, this plant produces white flowers with pale yellow or purple-dotted bases that generally fade to purple, measuring 3.5 to 8 millimeters long. Growing with slender stems that are glabrous or strigose, particularly near the base, it can be partially glandular-hairy toward the upper portions. Its leaves feature terminal leaflets less than 60 millimeters long, narrowly ovate in shape, with lateral leaflets typically larger and sometimes purple-dotted. The plant's hypanthium measures 3 to 5.5 millimeters long, with sepal tips remaining inconspicuous and free in the bud.
