Cyrillaceae
 The Cyrillaceae are a small family of flowering plants in the order Ericales native to warm temperate to tropical regions of the Americas. The family comprises two genera each with a single species Cyrilla racemiflora and Cliftonia monophylla.In the past many botanists included a third genus Purdiaea in the family though recent research has shown this genus is better placed in the closely related family Clethraceae.
