Leaves growing farther up the stem are smaller and have more lobes on their blades.  The inflorescence contains several flower heads, each lined with dark green phyllaries.  The head contains many golden yellow disc florets and generally either 8 or 13 yellow ray florets each over a centimeter long.  The fruit is an achene tipped with a pappus of bristles.
