Description

It is an annual herb producing a flowering stem up to about 45 centimeters high. The pinnately lobed linear to lance-shaped leaves are mostly located around the base of the plant. The lobes are generally threadlike to linear. The inflorescence is a flower head borne singly lined with hairy-based phyllaries, usually 20 to 26 or more in 2 to 3 or more series. Each bract often has a red midstripe. The 16–20 millimetres (0.6–0.8 in) head bears rings of ray florets, usually yellow to pale yellow, but sometimes white.[2]
