Aniscoma acaulis is an annual herb with naked (leafless) smooth stems and an inflorescence of a single flower. The greenish-yellow phyllaries that contain the petals overlap appearing as scales, giving the plant its common name. Scales and petals have a red/pink midline that is not noticeable if viewing the flower from the top. Pipes Canyon, CA | March 29, 2015
