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.) |
In the flora area, Ipomoea purpurea may be native in southeastern United States and introduced elsewhere. Populations in California, Oregon, and Washington may not be truly naturalized. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
