Layia heterotricha is a species of flowering plant in the daisy family known by the common name pale yellow tidytips, or pale yellow layia. L.heterotricha is an annual herb producing a thick, erect stem to a maximum height near 90 centimeters.

The flower head contains white to pale yellow ray florets each up to an inch long, and many yellow disc florets with yellow anthers. The fruit is an achene; fruits on the disc florets often have a long pappus. [Calscape, Jepson]
