Description

Lessingia hololeuca is an annual herb varying in maximum size and shape from flat and just a few centimeters high to an erect 40 centimeters tall. It is mostly woolly in texture. The lower leaves approach 13 centimeters long and may have several deep lobes; the upper leaves much smaller and unlobed. The flower heads appear singly or in crowded clusters. Each head has a bullet-shaped involucre lined with woolly, purple-tipped phyllaries. The head is discoid, containing no ray florets but many funnel-shaped pink, lavender, or purple disc florets with lobes that resemble ray florets. The fruit is an achene with a whitish pappus of bristles.
