Lasthenia glabrata is a North American species of flowering plant in the daisy family known by the common names yellowray goldfields and yellow-rayed lasthenia. It is endemic to California, where it is a resident of vernal pools and other moist areas in a number of habitat types. It is widespread across much of the state, from San Diego County to Tehama County. Lasthenia glabrata is an annual herb growing up to 50 cm (19.5 in) tall. The thin stem has a few pairs of oppositely-arranged, smooth-edged linear leaves each up to 15 centimeters (5.9 inches) long. The plant flowers in solitary or loosely clustered flower heads with 7-15 yellow ray florets surrounding numerous disc florets. The fruit is an achene a few millimeters long with no pappus.
