About Pulicaria paludosa Welw. ex Nyman, 1879
Pulicaria paludosa is a species of flowering plant in the aster family, with the common name Spanish false fleabane. It is native to Europe, especially Spain and Portugal. It is an introduced species in California, Arizona, and Clark County, Nevada, where it grows as a weed on roadsides, wetlands, riparian corridors, and other damp, disturbed areas. This herb can be annual, biennial, or perennial. It grows from a rhizomatous root system, and reaches heights ranging from a few centimeters to well over one meter. Its leaves are arranged alternately, and their blades come in a range of shapes, including linear, oblong, and oval. The entire aboveground plant is covered in soft hairs. Its inflorescence produces many flower heads. Each flower head has narrow, pointed, hairy phyllaries, a large dense center made of many yellow disc florets, and a short fringe of many rectangular yellow ray florets. Each individual ray floret is only about 2 millimeters long. The fruit produced by this plant is an achene, tipped with a pappus made of bristles.
