Endemic to Cuba growing in sandy plain near Camagüey.

CUBA. Sine loc., C. Wright 3086 (K). Camargüey: La Ciega, Caobillas, J. Acuña 1540 (HAC); Sabana de Croms, Bro. León & M. Victorin 17641 (HAC); Guaímaro, al norte de Monte Grande, R. Berzaín et al. (HAJB31501).

Note.

This species has been identified as Ipomoea cavanillesii , a synonym of I. cairica . It has nothing to do with I. cairica and from the structure of the sepals and the leaf shape, it is probably closest to Ipomoea eggersiana .
