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.

The leaves are lance-shaped, up to 8 centimeters long, and coated in silky hairs. The plant produces an inflorescence up to about 15 centimeters tall consisting of a solitary flower head which is cylindrical to somewhat bell-shaped. The head is enclosed in the fused outer scales of the flowers, which look similar to the phyllaries of many other species' flower heads. The head contains many yellow disc florets up to a centimeter long each, and no ray florets. The fruit is a long, narrow achene which may be 2 centimeters in length including its plumelike pappus.
Senecio blochmaniae is an uncommon species of flowering plant in the aster family known by the common names dune ragwort and Blochman's ragwort. It is endemic to the Central Coast of California, where it is known only from the direct coastline of San Luis Obispo and Santa Barbara Counties. It grows in sand dunes and sandy areas on coastal floodplains. It is a subshrub producing several arching stems often well exceeding a meter tall from a thick taproot. The stems are covered in many leaves, which are linear in shape, thick, and measure up to 12 centimeters long. The lower leaves become dry and curl up. The flower heads are lined by about 13 green-tipped phyllaries. They contain many yellow disc florets and each has usually 8 narrow yellow ray florets about a centimeter long.
Packera bolanderi is a species of flowering plant in the aster family known by the common names Bolander's ragwort and seacoast ragwort. It is native to the west coast of the United States from Washington to northern California, where it grows in wet coastal forests and woodlands. There are two varieties of the species which differ slightly in morphology and habitat occupied; these varieties have been considered separate species by some authors. The var. bolanderi has thicker leaves, occurs farther south, and occupies more open types of habitat, than does var. harfordii. This plant in general is a perennial herb producing one to three stems up to half a meter tall. The basal leaves have blades up to 12 centimeters long which are divided into several lobes and borne on long, thin petioles. 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.

It is endemic to the Sierra Nevada of California, where it grows in the moist meadows on the western slopes of the range. It is a perennial herb growing up to 1.2 meters tall from a caudex and fibrous root system. The solitary erect stem is lined evenly with leaves up to about 18 centimeters long, their blades deeply lobed or dissected into narrow, pointed segments. The herbage is hairy to woolly in texture. The inflorescence bears several flower heads which are lined with green-tipped phyllaries. They contain many yellow disc florets and each has usually 8 or 13 narrow yellow ray florets about a centimeter long, sometimes longer.
