Discussion
According to J. E. Eckenwalder (1986), the name Ipomoea × multifida Rafinesque (as species) refers to diploid hybrid plants resulting from crosses between I. coccinea and I. quamoclit; I. sloteri refers to allotetraploid plants derived from diploid hybrids between I. coccinea and I. quamoclit.
