Material of this species was identified in FRPS as Solanum coagulans Forsskål, a species from eastern Africa and Arabia which has unequal anthers. The name S. incanum Linnaeus has commonly been used for this species, but recent neotypification of that name calls for applying it to a species from northeast Africa and the Arabian Peninsula that has more pubescent leaves with narrower apices and smaller fruits. The application of S. undatum or S. cumingii to this species is uncertain.
