Clappia suaedifolia is the sole species in the North American genus of flowering plants in the family Asteraceae, Clappia.

[3][4] Clappia suaedifolia is native to Texas and Tamaulipas.

It is a succulent, branching shrub or subshrub up to 30 cm (12 inches) tall.

[5][6][7] The genus is named for Dr. Asahel Clapp, of New Albany, Indiana.

[3] Annotations on the type specimen of Haplopappus nealleyi in the US National Herbarium,[8] on which the genus Stanfieldia and sole species Stanfieldia nealleyi were also based,[9] suggest that these later names may be synonyms of Clappia suaedifolia.
