"Layia pentachaeta" is a species of flowering plant in the daisy family known by the common name Sierra tidytips, or Sierra layia. It is endemic to California, where it grows in a number of habitats in the central part of the state from the Sierra Nevada to the Tehachapi Mountains. This is an annual herb growing a thick stem up to a meter tall, but often remaining shorter. The stem is coated in glandular hairs whose exudate gives the plant a sharp lemonlike scent. The thin leaves are linear to lance-shaped, with the lower leaves lobed and approaching 11 centimeters in maximum length. The flower head contains white or yellow ray florets and yellow disc florets with yellow anthers. The fruit is an achene; fruits on the disc florets often have a white bristly pappus.
