Discussion | Ipomoea imperati was collected once in Pennsylvania (on ballast in 1865). The names I. littoralis (Linnaeus) Boissier 1875, not Blume 1826, and I. stolonifera (Cirillo) J. F. Gmelin are illegitimate; both have been misapplied to plants of I. imperati. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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.
