¹A previous lectotypification of this name by Pennington [in Jarvis et al. (ed.)] Regnum Veg. 127: 40. 1993) as Plumier (Burman ed.) Nov. Pl. Amer. tab. 110. 1757, is here superseded because this element was not cited in Linnaeus’ original description of Cupania americana. Linnaeus instead, cited Plumier, Nov. Pl. Amer. Gen. 45. 1703. (Tab 19.1), which is a highly inadequate illustration to be used as the type for C. americana, therefore, an epitype is necessary. Cupania americana is herein treated in the wide sense and includes several of the species recognized by Radlkofer in his treatment of the family Sapindaceae (1931-1934). Further studies are necessary before infraspecific taxa could be recognized within this species complex.
