Description

This is an annual herb producing an erect stem to a maximum height just over one-half meter (1 ft 8 in). The stem and foliage are dotted with dark glandular hairs and the plant is sometimes scented. The thin leaves are linear to oval-shaped, with the lower ones often lobed, approaching 10 centimeters (4 in) in maximum length.[3][2]

The flower head has a base of green, hairy, glandular phyllaries. The face is fringed with 3–14 (typically 5) broad, 3-lobed ray florets which are usually white, but sometimes yellow. The center contains yellow disc florets with yellow anthers. The fruit is a hairy achene; fruits on disc florets have a pappus of stiff white hairs.[3][2]

The species is similar to Blepharipappus scaber, which has white disc flowers.[4]
