Discussion

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.
