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.) |
Reports for Ipomoea quamoclit from Kansas, Oklahoma, Texas, and Virginia may be from horticultural plantings. A report from California is from a casual garden weed; it is not naturalized there. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
