Raillardella pringlei is an uncommon species of flowering plant in the aster family known by the common name showy raillardella. It is endemic to the southern Klamath Ranges of northern California, where it grows in moist forest habitat on serpentine soils. It is a rhizomatous perennial herb growing in a clump of rosetted basal leaves. The leaves are linear to lance-shaped with smooth or faintly toothed edges, up to 15 centimeters long, and mostly hairless. The plant produces an inflorescence generally 25 centimeters to half a meter tall consisting of a solitary flower head or an array of up to three heads. The head is bell-shaped, sometimes widely so. It contains many orange to red-orange disc florets each about a centimeter long, and a fringe of several orange or reddish ray florets each up to 2 centimeters in length. The fruit is a long, narrow achene which may be 2 centimeters in length including its pappus of plumelike bristles.
