Description

Layia pentachaeta is an annual herb growing a thick stem up to a meter (3 ft) 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.
