Distribution and habitat: Brazil, endemic. It occurs in sandy soils within Caatinga vegetation of Tropical Dry Forests.

Conservation Status: Endangered (EN). Zornia afranioi is known only from northeastern Brazil and is restricted to a relatively small area of approximately 64 km ², resulting in an extremely limited AOO (EOO= 182,338.732 km ²; AOO= 64 km ²).

Notes: Zornia afranioi differs from the other species in the genus by a combination of its erect stems and its bracteoles ovate and pubescent.
