Genipa, the genip-trees, are a genus of flowering plants in the family Rubiaceae.
 This genus is closely allied to "Gardenia"; several "Gardenia" species were originally placed in "Genipa".
 It is not to be confused with genip ("Melicoccus bijugatus"), a completely unrelated eudicot.
 The name is derived from "genipapo", the Guianan name for "G. americana" (commonly known as huito).
 The genus is also commonly called jagua, xagua or xaqua.
Casasia is a genus of flowering plants in the Rubiaceae family.
 These shrubs or small trees occur on the Caribbean islands and in one case (Seven-year Apple, "C. clusiifolia") in Florida.
 Some of the ten accepted species were formerly placed elsewhere, e.g. in the related genip-tree genus ("Genipa"), in "Gardenia" or in "Randia".
