Discussion | Cordylanthus nidularius is the only member of the genus with decumbent stems. The species is similar to C. tenuis; it differs in its white (versus pale yellow) corollas and decumbent (versus erect to ascending) stems. It grows on the eastern slopes of Mt. Diablo.

Cordylanthus capitatus is often associated with Artemisia tridentata and may be hemiparasitic on it. Cordylanthus capitatus is distinguished by having only two anthers, each with one fertile pollen sac; infertile vestiges of the second pollen sac usually are present. The species can be recognized by its short-capitate inflorescences, the single, spathelike, deeply cleft calyx lobe, and the purple-red corollas with yellow tips.
