Description
Layia hieracioides is an annual herb producing a thick, glandular, strongly scented stem to a maximum height near 1.3 meters, but often remains shorter. The thin leaves are linear to lance-shaped, with the lower ones lobed or toothed and up to nearly 15 centimeters in maximum length. The flower head has a rounded to urn-shaped base of green phyllaries covered in dark glandular hairs. The head contains short yellow ray florets only a few millimeters long around a center of yellow disc florets with purple anthers. The fruit is an achene; fruits on the disc florets have a pappus of bristles.
