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.) |
Ipomoea tricolor is native in Mexico and has long been cultivated in North America. The name Ipomoea violacea has been misapplied to plants of I. tricolor. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
