Acaciella angustissima is recorded for the first time from Cuba. In its native range, it is widespread from the southern USA across Mexico, Central America and the Andes to Argentina. In Cuba, it has been found near Camagüey city, in anthropogenic habitats, indicating recent unintentional introduction. The Cuban plants match the typical variety, A. angustissima var. angustissima.
