Pulicaria paludosa
Pulicaria paludosa is a species of flowering plant in the aster family known by the common name Spanish false fleabane. It is native to Europe, particularly Spain and Portugal, and it is known as an introduced species in California, where it grows as a weed on roadsides and other damp, disturbed areas. It is an annual, biennial, or perennial herb growing a few centimeters tall to well over a meter tall from a rhizomatous root system. The leaves are alternately arranged with blades in a variety of shapes from linear to oblong or oval. The herbage is coated  in soft hairs. The inflorescence bears many flower heads. Each head has narrow, pointed, hairy phyllaries, a large dense center of many yellow disc florets, and a short fringe of many rectangular yellow ray florets, which are only about 2 millimeters long each. The fruit is an achene tipped with a pappus of bristles.
